[SYMPTOM]
 
 
 
 
     When mixing KI10 and  KL10  compiled  code,  LINK  will
catch  the  conflict  and  give  an  error  message, but the
message will complain about mixing KA10  and  KI10  compiled
code.
 

                        **********


[DIAGNOSIS]
 
     LINK doesn't understand REL files containing  the  KL10
flag.
 

                        **********


[CURE]
 
     Until LINK is taught about KL10 REL files,  just  treat
them like KI10 REL files.

                        **********


[SYMPTOM]
 
 
 
 
     When loading a large program, or one containing PSECTs,
LINK can go into a loop.  If /ERR:0 is set, a LNKMOV message
referring to a non-existent or junk area name will  probably
be seen.
 

                        **********


[DIAGNOSIS]
 
     If the first address LINK sees is above 400000, then it
starts  loading  relative  to  the  first address seen in an
attempt to save disk overflow time for speed.  If an address
below  the  first  one is seen later, then LINK gives up and
overflows to disk.
 
     Unfortunately, the disk overflow routine it calls is  a
local  routine  in  LINK's  memory manager that is otherwise
only called when LINK is trying to expand and discovers that
it  must  write  a  new  area to disk in order to do so.  In
fact, the routine assumes that it  was  called  under  those
conditions,  and  makes  other calls to finish the expansion
process that it thought was in progress before returning  to
its caller.
 
     That assumption is not valid in this case, so  none  of
the memory manager's registers etc. are set up.  This causes
the other calls back into the memory manager to "finish" the
expansion to loop.
 

                        **********


[CURE]
 
     Before calling  the  disk  overflow  routine,  set  the
memory  manager's register containing the number of words to
expand to zero,  thus  causing  it  to  return  immediately,

                        **********


[SYMPTOM]
 
 
 
 
     LINK may fail with the LNKCEF message  at  the  end  of
loading, just after the LNKSST message has been typed.
 

                        **********


[DIAGNOSIS]
 
     If the area into which the undefined symbol table is to
be  loaded  is not paging to disk, and if the area cannot be
expanded enough to contain the first word of  the  undefined
symbol  table  without  overflowing  to disk, then LINK will
fail with the LNKCEF message.  There is simply  no  code  to
start the appropriate area paging at that point.
 

                        **********


[CURE]
 
     Add code to consider the case.

                        **********


[SYMPTOM]
 
 
 
 
     Illegal Instruction when  loading  an  extremely  large
program.   This  will  only happen when running a version of
LINK whose high segment starts above 400000, as it  does  on
TOPS-20.
 

                        **********


[DIAGNOSIS]
 
     LINK's POP loop to move memory areas up can only handle
an  area of 377777 words or less.  If one of the areas grows
beyond this, then LINK will split the move up into  multiple
moves.   Unfortunately,  the  code  to do this PUSHes a word
onto the stack that is never POPed back off.
 

                        **********


[CURE]
 
     POP the extra word off at the end of the loop.

                        **********


[SYMPTOM]
 
 
 
 
     Illegal memory reference or LNKPUF error in LNKXIT when
loading  a  program using overlays, after the LNKCSF message
has been typed.  The LNKCSF  message  will  only  appear  if
/ERR:0 is set.
 

                        **********


[DIAGNOSIS]
 
     If the routine GSDLT is called with the GS area already
gone,  then  it  can  leave the UB pointer of the next lower
area pointing beyond .JBREL.
 

                        **********


[CURE]
 
     Make GSDLT check to see if the GS area is already gone.

[SYMPTOM]
 
 
 
 
     LINK can get an address check error  from  the  monitor
when  writing an EXE file.  This will only happen if LINK is
paging to disk.
 

                        **********


[DIAGNOSIS]
 
     LINK's calculation of the new upper window  bound  when
advancing  to  the next window is incorrect, causing a later
OUT UUO to get an address check.
 

                        **********


[CURE]
 
     Correct the calculation to not  add  one  to  a  number
which is already correct.

                        **********


[SYMPTOM]
 
 
 
 
     LINK does not  ignore  the  starting  address  of  the  user's
FORTRAN  program  when  /DEBUG:FORTRAN is specified.  FORDDT always
wants control before the FORTRAN program.
 

                        **********


[DIAGNOSIS]
 
     LINK correctly guarantees that FORDDT is loaded after the file
(if  any)  on  which  /DEBUG:FORTRAN  is  specified,  thus  causing
FORDDT's starting address to override that file's starting address.
But  if any later modules with starting addresses are loaded, these
then override FORDDT.
 

                        **********


[CURE]
 
     Force starting addresses from all  subsequent  modules  to  be
ignored.

                        **********


[SYMPTOM]
 
 
 
 
     LINK gets an address check if all of the following  conditions
are met:
 
     1.  Loading a program small enough that LINK doesn't  need  to
         page to disk
 
     2.  Loading no data into pages 0 or 1
 
     3.  Specifying /SAVE to get an EXE file
 
In this case, LINK is also not outputting the  program  version  to
the EXE file.
 

                        **********


[DIAGNOSIS]
 
     The special routine to handle EXE file writing  when  no  data
exists in pages 0 or 1 does not get JOBDAT from the LC area if LINK
didn't have to page to disk.  The resulting dump-mode IOWD to write
JOBDAT to the EXE file causes the address check.
 
     Also, the length in the IOWD is set up to output one word  too
little.   Since  .JBVER  (the  location  in  JOBDAT  containing the
program version) is the last location in  JOBDAT,  it  doesn't  get
written.
 

                        **********


[CURE]
 
     Check if not paging and if so, get JOBDAT from  the  LC  area.
Also  output  all  of  JOBDAT  so the program version gets written.
Note that this edit has been superseded by edit  1134,  and  should

                        **********


[SYMPTOM]
 
 
 
 
     If a COMMON block is referenced before it is defined (as in an
assembly  program followed by a FORTRAN program), LINK allocates the
size of the COMMON incorrectly.
 

                        **********


[DIAGNOSIS]
 
     After defining the COMMON block, LINK calls  SY.RF  to  update
any  now-definable  symbols.   It then allocates the memory for the
COMMON block from  its  symbol  definition.   Unfortunately,  SY.RF
destroys  the  pointer  to the COMMON block symbol, causing LINK to
get the wrong size.
 

                        **********


[CURE]
 
     Save the  symbol  table  pointer  over  the  SY.RF  call,  and
document SY.RF as not saving P1-P4 to help prevent this kind of bug
in the future.

                        **********


[SYMPTOM]
 
 
 
 
     LINK can get an address check error on TOPS-10 or write
a  bad  EXE file that is excessively large on TOPS-20 if all
of the following conditions occur:
 
     1.  The program being loaded contains  no  low  segment
         code  or  PSECTs  other  than  the  job  data area,
         although it may contain high segment code.
 
     2.  The user has requested a runtime DDT  symbol  table
         to  be  loaded  into  the  low segment (this is the
         default on TOPS-20).
 
     3.  LINK is writing an EXE  file,  either  because  the
         program  is  too  large  to  load  into  memory, or
         because the user has requested  it  with  /SAVE  or
         /SSAVE.
 
 

                        **********


[DIAGNOSIS]
 
     In this case, LINK has set its lowest  location  loaded
(LOWLOC)  to  the  base  of  the high segment if there, or a
random positive number if not.  Unfortunately, it  does  not
update  this  quantity  when  it decides to place the symbol
table below anything yet loaded, and the EXE file  generator
believes the incorrect value and blows up.
 

                        **********


[CURE]
 
     When generating the runtime symbol table, check to  see
if  it is being placed below any code yet loaded, and update
LOWLOC if so.

                        **********


[SYMPTOM]
 
 
 
 
     LINK may die with various memory  management  errors  (illegal
memory  references,  ?LNKRUC,  etc.)  any  time after the map phase
(e.g., in the plotting phase), under the following conditions:
 
     1.  Loading an overlaid program
 
     2.  Giving names to some, but not all, links
 
     3.  Asking for a map
 
 

                        **********


[DIAGNOSIS]
 
     When LINK is finished printing the map, it frees the memory it
used   to  sort  the  index  of  link  names  (module  names  in  a
non-overlaid program).  In freeing  this  memory,  LINK  tells  its
memory  manager  to  free enough words to sort all link (or module)
names.  Unfortunately, the last index printed  in  the  map  of  an
overlaid  program  is that of link names, which may be shorter than
the total number of links loaded if some were not given names.   In
this  case,  LINK  frees  more  words than it originally allocated,
leaving free memory messed up.  Any later routine allocating memory
may thus die with memory management errors.
 

                        **********


[CURE]
 
     Treat the overlay link indexes as special cases, and only free
the last index of module names at the end of the map.

                        **********


[SYMPTOM]
 
 
 
 
When searching an indexed library created with MAKLIB,  LINK
can  get an LNKIRB (LNKILI in version 3A and earlier) error.
This is only possible  if  some  module(s)  in  the  indexed
library  contain no entry points.  This error will not occur
if such module(s) are removed, or if the  index  is  created
with FUDGE2.
 

                        **********


[DIAGNOSIS]
 
     When LINK is searching an indexed library,  it  assumes
that  each  module present in the library is also present in
the index.  This was true with libraries created by  FUDGE2,
but  MAKLIB compresses modules that have no entry points out
of the index.
 
     LINK makes this assumption in two ways.   First,  after
loading  some  module, if LINK wants to load the next module
in the index, it assumes that it can just  continue  reading
the  REL file, without doing any positioning.  Second, after
loading some module, if LINK decides NOT to  load  the  next
module  in  the  index, it remembers the address of the next
module anyway, on  the  assumption  that  its  input  stream
pointers  now  point  there,  having  just finished with the
module before it.
 
     Since this assumption is no longer  true  with  MAKLIB,
LINK  can  get confused and start reading at the wrong place
in the library, thus getting LNKIRB errors.
 

                        **********


[CURE]
 
     Remove  all  of  the  special  checks  that  make  this
Digital Equipment Corporation       28-AUG-79    Page  56
PCO Log Report


assumption.  Instead, have the low level input routines keep
track of where LINK is in the current REL file, and make the
indexed library processor use this information.

[SYMPTOM]
 
 
 
 
     Loading very large programs  can  cause  ?LNKILC  errors  with
status  20016  (end of file) when a request to load a word early in
the program (such as initializing FORTRAN COMMON) is followed by  a
request to load a word within a few pages of 512P.
 

                        **********


[DIAGNOSIS]
 
     In the case above, LINK must move the window into the overflow
file from the beginning of the memory image to somewhere near 512P.
In this case, no check is made to keep the window in bounds.  Since
all  of  LINK's  subsequent  code  depends  on  memory images never
exceeding 512P, it reads in the new window from past the end of the
overflow file.
 

                        **********


[CURE]
 
     If the window is about to cross the 512P  boundary,  slide  it
back so the end of the window just fits inside 512P.

                        **********


[SYMPTOM]
 
 
 
 
     The observed symptom was LINK going into a loop after  loading
the  first  link  after  the  root  in an overlaid COBOL version 12
program.  However, a wide  variety  of  errors  are  possible,  all
related  to  LINK's  dynamic  area  free list getting trashed.  The
dependency on COBOL is caused  by  use  of  .REQUEST/.REQUIRE  (REL
block types 16 and 17) which COBOL version 11 did not use.
 

                        **********


[DIAGNOSIS]
 
     At the end of  loading  the  root,  LINK  frees  its  list  of
.REQUEST/.REQUIRE     blocks,     following    their    processing.
Unfortunately, the pointer to the now free list  was  not  cleared,
causing  LINK  to  free the same blocks again at the end of loading
the next link.
 

                        **********


[CURE]
 
     Zero the pointer to the .REQUEST/.REQUIRE list  after  freeing
its contents.

                        **********


[SYMPTOM]
 
 
 
 
     LINK can get an address check  error  when  loading  an
extremely  large  program,  or  when loading in a restricted
amount of core on TOPS-10.
 

                        **********


[DIAGNOSIS]
 
     When LINK decides to overflow the LC  or  HC  areas  to
disk,  it  tries  to  move  about  half of the area into the
overflow file.  If half of the  area  is  less  than  LINK's
default  internal  window  size,  then LINK tries to move at
least that much into the file.  Unfortunately, if the entire
area  is also smaller than LINK's internal window size, then
LINK tries to shrink the area by more pages  than  the  area
contains.   This results in an OUT UUO with a positive IOWD,
with the resulting address check.
 

                        **********


[CURE]
 
     Remove the code that attempts to do this,  since  there
is  no  harm  in the window being too small (it will grow as
required).  It is necessary to output at least one page, but
this  will  never cause the above problem, since the area to
be output is always at least one page long.
 
     This edit removes part of edit 750,  and  restores  the
affected  area  of code to the way it looked in LINK version
3A and earlier.

                        **********


[SYMPTOM]
 
 
 
 
     When LINK is asked to write an EXE file, the  last  few
pages  of the low segment may not get written into the file.
This will only happen if the last thing in the  low  segment
is  a  PSECT  that  ends  with a BLOCK statement.  The words
represented by the BLOCK may be lost.
 

                        **********


[DIAGNOSIS]
 
     LINK will only write the low segment as far  as  HL.S1,
the  pointer  to the last location in the low segment, tells
it to.  Unfortunately, this location  is  incorrect  if  the
last thing in the low segment is a PSECT.
 

                        **********


[CURE]
 
     Make sure that this word is at least as big as the  end
of the highest PSECT loaded.

[PCO Write-up]



                        **********


[SYMPTOM]
 
 
 
 
     Could be anything,  including  LNKRUC  errors,  illegal
memory  references,  etc.   The  observed  symptom was a bad
PSECT name typed out as part of the  LNKPOV  message.   This
will  only  happen when loading a program that contains more
than ten PSECTs.
 

                        **********


[DIAGNOSIS]
 
     When LINK's PSECT table fills up, LINK  deallocates  it
and  allocates a new larger one.  Edit 706 (included in LINK
4) added a new PSECT table, thus requiring LINK to  free  up
and  reallocate two tables.  Unfortunately, the new code got
confused, thus freeing up the same block twice.
 

                        **********


[CURE]
 
     Instead  of  doing  two  allocations  followed  by  two
deallocations, do two allocation/deallocation sequences, and
fix the register usage to keep all the required  information
around.

[SYMPTOM]
 
 
 
 
     When edit 772 is installed, LINK can die  with  I/O  to
unassigned channel errors when writing an EXE file.
 

                        **********


[DIAGNOSIS]
 
     The left half of P2 and P4 are left set up  with  junk,
so address compares fail.
 

                        **********


[CURE]
 
     Zero the left halves.

[SYMPTOM]
 
 
 
 
     If a segment is exactly a multiple of 1000 words  long,
then  the  LINK map will report that it is one P (or K on KA
systems) longer than it really is, and the number  of  words
free in the segment will be reported as 512 instead of zero.
 

                        **********


[DIAGNOSIS]
 
     LINK rounds up to the next 1P boundary by oring in 777,
and  then  adding  one.   This gives incorrect results for a
number already on a page boundary.
 

                        **********


[CURE]
 
     Round up  by  adding  777,  then  truncating  to  a  1P
boundary.

                        **********


[SYMPTOM]
 
 
 
 
     When loading an overlaid program and asking for a plot of  the
overlay  tree,  LINK  dies  with various errors, usually an illegal
memory reference.  This error is more common when the overlay  tree
is printed in line printer format, or if the tree is very large.
 

                        **********


[DIAGNOSIS]
 
     LINK is trying to expand memory while plotting the  tree,  and
tries to move the LC area for more room.  However, plotting is done
after everything else, so no LC area exists.  On TOPS-20,  this  is
compounded  by LINK's memory manager believing that it has expanded
as much as possible, even though the plotting code has shrunk back.
 

                        **********


[CURE]
 
     Change LINK's memory manager to give LNKCEF if it has expanded
as  much  as  it  can,  and there are no areas that can be moved or
paged out.  On TOPS-20, see that LINK really does not  shrink  back
until  final  program  placement,  so  that  the  memory  manager's
assumptions are true.  Finally,  add  a  new  message,  LNKPOT,  to
inform the user when LINK is plotting the overlay tree.

                        **********


[SYMPTOM]
 
 
 
 
     LINK allocates too much  room  for  modules  after  any  COBOL
module  used with /LOCALS or ALGOL module, when all the modules are
in a single REL file that is  not  being  loaded  with  /SEARCH  or
/INCLUDE.  This causes programs to load much larger than necessary.
 

                        **********


[DIAGNOSIS]
 
     COBOL symbols and ALGOL OWNs are not counted  in  the  segment
break in REL block 5 (END), so that LINK must count them separately
and add them in at the end of the module.  Unfortunately, when  the
conditions  above  are  met,  LINK neglects to zero them when it is
through.  Thus, the lengths get added in to each subsequent  module
in the REL file.
 

                        **********


[CURE]
 
     See that the counts get zeroed immediately after use.

                        **********


[SYMPTOM]
 
 
 
 
     No complaints from LINK when loading high segment  code  in  a
link  other  than the root in an overlaid program.  This frequently
happens when a user attempts to  build  an  overlaid  program  with
COBOL modules compiled with the /R COBOL switch.
 

                        **********


[DIAGNOSIS]
 
     LINK's overlay facility depends  completely  on  all  code  in
links other than the root residing in the low segment.  However, no
load-time check is made to save  users  much  grief  and  confusion
later.
 

                        **********


[CURE]
 
     Add a check, and new message LNKHCL.

[SYMPTOM]
 
 
 
 
     Large areas of the program being loaded will  be  lost;
there  will  be  zeros  where there should be code and data.
This will only happen  when  loading  a  program  that  uses
PSECTs, or any large program that does not load some segment
monotonically (e.g., LOC or RELOC  statements  are  used  to
skip  around  in the address space being loaded).  This will
only happen in LINK version 4 or later.
 

                        **********


[DIAGNOSIS]
 
     Part of edit 716 removed code to read in data that  had
already been loaded above the point where data was currently
being placed.  Unfortunately, if the data is not read in, it
will be lost.
 

                        **********


[CURE]
 
     Remove that portion of edit 716;  replace the  original
code.

                        **********


[SYMPTOM]
 
 
 
 
The command string
 
     /INCLUDE:A D.REL
 
does not load module A from D.REL.
 

                        **********


[DIAGNOSIS]
 
There are two operations performed by the /INCLUDE switch.   First,
the switch's arguments (if any) are added to the list of modules to
be loaded when a file is in `include mode'.  Second,  /INCLUDE  may
also set `include mode'.
 
In old versions of LINK, /INCLUDE did both operations all the time.
Thus,
 
     /INCLUDE:(A,B,C) D,E,F
 
loaded only modules A, B and C from REL files  D,  E  and  F.   The
problem  was that if, say, a user wanted all modules in E.REL to be
loaded, there was no way to turn off the `include mode'  action  of
the sticky /INCLUDE.
 
Therefore, an edit was made to partially decouple the  two  actions
of  /INCLUDE, so that specifying /INCLUDE with arguments only added
module names to the list of those  to  include,  but  did  not  set
`include mode'.  A /INCLUDE switch without any arguments would then
set `include mode' for a file.  Thus, in  the  above  example,  one
could type
 
     /INCLUDE:(A,B,C) D/INCLUDE,E,F/INCLUDE
 
and get the desired results of looking for modules A, B  and  C  in
REL files D and F, but loading all modules in E.
 
Unfortunately,  this  action  is  counter-intuitive,  and  required
Digital Equipment Corporation       28-AUG-79    Page 129
PCO Log Report


numerous   and  seemingly  redundant  specifications  of  /INCLUDE.
Another problem was that after the edit,  /INCLUDE  specified  with
arguments  for a specific file (such as D/INCLUDE:A) would also set
`include mode'.   This  made  the  action  of  /INCLUDE  even  more
difficult to understand.  In particular, the obvious case mentioned
in the symptom above no longer worked.
 

                        **********


[CURE]
 
Put /INCLUDE back the way it was so that it  always  sets  `include
mode'  along  with adding any specified module names to the list to
be checked.  However, also add a new switch /NOINCLUDE  which  will
temporarily  turn  off `include mode' without affecting the list of
modules to  include.   To  clarify  the  new  setup,  consider  the
following examples:
 
/INCLUDE:A D
 
          will load only module A from B.REL
 
/INCLUDE:(A,B,C) D,E,F
 
          will load only modules A, B and C from REL files D, E and
          F
 
/INCLUDE:(A,B,C) D,E/NOINCLUDE,F
 
          will load only modules A, B and C from REL files D and F,
          but will load all of E.REL.
 
/INCLUDE:(A,B,C) D,/NOINCLUDE E,F,/INCLUDE G
 
          will load only modules A, B and C from REL files D and G,
          but will load all of REL files E and F
 
Note that /NOINCLUDE takes no arguments;  its only intended use  is
to temporarily turn off `include mode' for certain files.
 
Also, since the switch table in LNKPAR is changed by this edit,  it
is  suggested that all of LINK's modules be recompiled, rather than
just those explicitly edited by the following FILCOM.

[PCO Write-up]



                        **********


[SYMPTOM]
 
 
 
 
LINK doesn't handle the CPU type bits in the title REL block  (type
6) correctly.  Some of the possible symptoms are:
 
     1.  Saying .DIRECTIVE KA10,KI10 in a MACRO program causes LINK
         to  indicate in the map that the module was built for a KL
         only.
 
     2.  `LNKKIA Cannot mix KI and KA compiled code'  results  even
         when the mismatch is due to a KL specification.
 
Edit 766 only compounded the problem, by treating KIs  and  KLs  as
the same.
 

                        **********


[DIAGNOSIS]
 
The field in the title REL block allows specification of a  set  of
CPUs  on  which  the module may run, not just a single CPU.  LINK's
tables and checks believe that the CPU field is  a  single  number,
one for each CPU type.
 

                        **********


[CURE]
 
Make LINK understand the CPU type bits as defined in the title  REL
block.  This involves a number of changes:
 
     1.  Remove edit 766 if it was installed (the FILCOM shows  the
         removal of edit 766).
 
     2.  Keep a mask of all CPUs on which the program being  loaded
         will run, and update it as modules with CPU specifications
         are read in.  If loading a module with a CPU specification
         keeps  the entire program from running on any type of CPU,
Digital Equipment Corporation       28-AUG-79    Page 136
PCO Log Report


         give the message
 
              ?LNKCCD CPU conflict detected in module [module]
 
     3.  Remove the LNKKIA message.
 
     4.  Print all applicable CPU types specified for a  module  in
         the map (unless all CPUs were specified).
 
     5.  Indicate in the page header of the map after  the  program
         name,  all  CPUs  on  which  the  entire  program will run
         (unless all CPUs).  This is the logical  AND  of  the  CPU
         specifications of all loaded modules.

[SYMPTOM]
 
 
 
 
     After edit 772 is installed, users will not be able  to
define  undefined  symbols  correctly  with  DDT.   A closer
examination will reveal that the symbol table (pointed to by
.JBSYM)  and  the  undefined  table  (pointed  to by .JBUSY)
overlap.
 

                        **********


[DIAGNOSIS]
 
     After the code rearrangement in edit 772,  the  pointer
to  the  start  of the symbol table is no longer incremented
past the end of the undefined table.
 

                        **********


[CURE]
 
     Re-introduce the increment code.   This  edit  requires
that edits 770 and 772 be installed in LINK first.

                        **********


[SYMPTOM]
 
 
 
 
Version 4 of LINK broke the /VERSION  switch.   If  the  switch  is
specified  on an input file or with no file at all, .JBVER does not
get set.  Also, /VERSION does not override  version  specifications
(by LOCing to .JBVER) in REQUIREd files.
 

                        **********


[DIAGNOSIS]
 
The original problem in version 3A of LINK was that /VERSION had to
be  typed  to  6 characters, since SCAN also had a /VERSION switch.
Development for LINK version 4 attempted to solve  the  problem  by
doing  away  with  LINK's  /VERSION  switch, and trying to grab the
value of SCAN's /VERSION switch at all the right times.
 
There are two problems with this method:
 
     1.  There are many places where LINK internally  creates  SCAN
         blocks  (e.g.,  for REQUEST/REQUIREd files).  All of these
         places need to be changed  to  follow  SCAN's  conventions
         regarding  initial  switch  values (-1), since /VERSION is
         the first SCAN switch  that  LINK  cares  about  in  these
         cases.
 
     2.  SCAN's usage of /VERSION is different from  LINK's.   SCAN
         treats  /VERSION as a file-specific switch, so that typing
         /VERSION in front of a file specification would cause  the
         switch  to  apply  to  all  subsequent  files on the line,
         whether input or output.  However, LINK treats the  switch
         having a meaning only with respect to the file on which it
         is specified.
 
Though the first problem could be solved with a patch,  the  second
is   not  solvable  within  the  current  specifications  of  SCAN.
Therefore, another method is necessary.
 

                        **********

PCO Log Report


[CURE]
 
Put LINK's own /VERSION switch back in, as it  was  in  version  3A
(i.e., remove edit 740).  However, to solve the original problem of
having to type /VERSION  to  6  characters,  make  LINK's  /VERSION
switch unique in any abbreviation.  Thus, /V, /VE, /VER, /VERS, and
/VERSI are all valid abbreviations of /VERSION.
 
Note that the attached FILCOM shows the edit as if edit  1105  were
installed.  If this is not the case, simply remove the lines marked

                        **********


[740] in the DVINP. routine in LNKFIO.MAC instead of  those  marked

[SYMPTOM]
 
 
 
 
None, but if LINK's start  address  were  ever  moved  to  the  low
segment, ENTER error messages would be printed as LOOKUP messages.
 

                        **********


[DIAGNOSIS]
 
Setting up the  flag  meaning  an  ENTER  error  is  done  with  an
erroneous  HRL  instruction.   Currently,  this  loads LINK's start
address from vestigial  JOBDAT.   Since  the  flag  has  the  value
400000,  this  works only as long as LINK's start address is in the
high segment.
 

                        **********


[CURE]
 
Load the flag correctly.

[PCO Write-up]



                        **********


[SYMPTOM]
 
 
 
 
     LINK fails with an  error  like  "?nnnLHC  not  found".
This  will  only  happen  when loading a two segment program
large enough to force the high segment to overflow to  disk,
and only if the user types /SAVE/EXEC or /SAVE/DEBUG.
 

                        **********


[DIAGNOSIS]
 
     LINK uses the same pointers to store the low  and  high
segment  overflow  file  specs  as  it  does  to  store  the
corresponding save file specs.  This used to  be  OK,  since
LINK would always write a save file for a particular segment
on /SAVE if it overflowed to disk, because that  would  mean
that  it  existed.   With EXE save file generation, however,
both segments are saved into the "low segment" EXE file,  so
that  the  high  segment  pointer  is  left  pointing to the
overflow file if the high segment  code  overflows  to  disk
during the load.
 
     This is a problem because LINK's RUN  UUO  code  always
tries to run the high segment save file, and is only willing
to run the low segment file if  there  is  no  high  segment
file.   If  the  high  segment overflows to disk, this means
that LINK will try to run its temporary overflow file, which
has been deleted.
 

                        **********


[CURE]
 
     If generating EXE save files, always issue a RUN UUO to
the EXE file.

                        **********


[DIAGNOSIS]
 
     LINK  figures  out  where  to  GETSEG  its  other  high
segments  from  by  asking  the monitor where its first high
segment came from, then GETSEGging the other  high  segments
from  the  same  place.  Unfortunately, in monitors prior to
7.01, the  monitor's  database  that  remembers  where  high
segments  come from does not include SFD information, so the
path that LINK gets from the monitor is  incorrect  if  LINK
was run from an SFD.
 

                        **********


[CURE]
 
     If LINK finds itself running under a monitor  prior  to
7.01,  have  it  GETSEG  its  other  high segments using the
arguments that the user typed in the "R"  or  "RUN"  command
that  invoked  LINK,  and  which  are left in the ACs by the
monitor  when  LINK  starts.   These  arguments  should   be
sufficient  to  find  LINK's other high segments, since they
were sufficient to find LINK itself.   This  means  that  if
LINK  came from an SFD, then it was from some SFD accessible
by specifying the default path, since the monitor's  command
decoder  (and  the  arguments  left in the ACs) do not allow
SFDs to be specified explicitly.
 
     Note  that  this  change  means  that  LINK   will   do
non-physical-only  GETSEGs under monitors prior to 7.01, and
thus will not be secure  if  protected  execute-only.   LINK
will  be  secure under 7.01, because it will continue to ask

the monitor where its original EXE file  came  from  and  do
physical-only  GETSEGs to the resulting full path if running
under a 7.01 or later monitor.

[SYMPTOM]
 
 
 
 
     No symptoms have  been  observed  because  no  programs
require  it,  but the runtime symbol table generated by LINK
does not quite match the spec.   In  particular,  the  title
entry  for the module PAT.. (which is inserted by LINK) does
not have the negative length of PAT..'s symbol table in  the
left half of the value word.
 

                        **********


[DIAGNOSIS]
 
     There is no code to put it out.   It  was  probably  an
oversight.
 

                        **********


[CURE]
 
     Store the negated size of PAT..'s symbol table  in  the
left  half of the value word of the module name entry in the
runtime symbol table.

                        **********


[SYMPTOM]
 
 
 
 
Edit  650  broke  LINK's  ability  to  load  large  programs  in  a
relatively small amount of memory by specifying /MAXCOR.
 

                        **********


[DIAGNOSIS]
 
If LINK requests memory from an area that is not big  enough,  LINK
tries first to expand it to make the request fit in.  Prior to edit
650, LINK did this, but forgot to take into account the size of the
request  itself,  which  would  then  result  in  a LNKNEC message.
However, edit 650 made LINK always count the size of  the  request,
even  for  pageable  areas.  For these, callers of LNKCOR know that
the request may fail, and will then move the window to the  desired
address,  and  so the added amount of the request can cause LINK to
expand past the /MAXCOR value unnecessarily.
 

                        **********


[CURE]
 
Do not add in the size of the current request if the area for which
the  request  was  made  is  pageable,  i.e., the LC, HC, LS and AS
areas.

              **********


[SYMPTOM]
 
 
 
 
If the low segment of a FORTRAN or ALGOL program exceeds the origin
of  the associated OTS (object-time system) that will be brought in
at run-time, LINK forces the OTS to be loaded into the low  segment
(if  possible).   However,  this  determination  is made before the
system libraries are searched,  which  could  then  cause  the  low
segment  to  cross  the  OTS  origin.  This causes GETSEG errors or
other problems at run-time.
 

                        **********


[DIAGNOSIS]
 
The decision to load the OTS into the  low  segment  must  be  made
prior to the system library search, since totally different modules
from the library might be required for  the  low  segment  version.
However,  if the decision is made to GETSEG the OTS at run-time but
the low segment then grows past the OTS origin, it is too  late  to
back out to prevent a run-time error.
 

                        **********


[CURE]
 
Change the check so that a low-segment version of the OTS is loaded
if  the  low  segment has grown to within 40 (decimal) pages of the
OTS origin.  This is about  twice  the  size  of  the  low  segment
portion  of the sharable OTS, and will therefore guarantee that the
load will succeed.
 
Note however that this is only a  load-time  decision,  and  it  is
still  possible  for  the  user's  run-time  memory requirements to
exceed the room left below the OTS.  This can  generally  be  found
simply  by  trial  and  error,  and the /OTS switch used to force a
sharable OTS (if less memory is needed) or a  low-segment  OTS  (if
more memory is needed).

                        **********


[SYMPTOM]
 
 
 
 
     There are several problems that users may run  into  if
LINK tries to create an EXE file, as follows:
 
     1.  LINK will get an address check if the  low  segment
         ends on the last word of a page, and if the program
         is not so large that  LINK  needs  to  overflow  to
         disk.
 
     2.  LINK will get an address check if loading a PSECTed
         program.  This will occur if the lowest code loaded
         is at 2000 or above, and  the  program  is  not  so
         large that LINK needs to overflow to disk.
 
     3.  Any  absolute   code   loaded   beyond   the   last
         relocatable  code will be lost, and will not appear
         in the EXE file.
 
     4.  LINK will write a bad EXE  directory  when  loading
         overlays  if  the user gives a /SPACE switch with a
         small (less than a page) argument.
 
     5.  LINK will write a bad EXE directory if the  program
         being  loaded  is so complex that the EXE directory
         is longer than two pages.
 
     6.  The EXE file that LINK writes will be  bad  if  the
         user  loads any PSECTs at higher addresses than the
         high segment.  The high  segment  will  be  written
         into the EXE file twice.
 
     7.  LINK can write an EXE file that  does  not  contain
         page 0.  Instead, what should have been page 1 will
         be written as page 0, page 2  will  be  written  as
         page 201 and so on for some or possibly the rest of
         the EXE file.  This will happen if page 202 is  the
         lowest page that the user has loaded anything into.
 
     8.  PSECT attributes  specified  by  the  user  in  the
         source  program  will  be ignored by LINK, and will
         not appear in the EXE directory.

PCO Log Report


 
     9.  If the user is loading PSECTs and  requests  a  DDT
         symbol table, the symbol table written will contain
         junk.  LINK incorrectly writes each PSECT into  the
         symbol  table  as  a null module name once for each
         module that uses that PSECT.
 
    10.  LINK can get a ?LNKCNW error when loading PSECTs if
         the  user  has  requested a DDT symbol table.  This
         will happen if the last  program  loaded  does  not
         define  any more symbols after the first appearance
         of a PSECT statement for some PSECT that  LINK  has
         never seen before.
 
    11.  LINK can  overwrite  an  overlaid  PSECT  with  the
         symbol  table.   This will happen if the user tells
         LINK to  place  the  DDT  symbol  table  after  the
         overlaid   PSECT,   using   the  /SYMSEG:PSECT:name
         switch.
 
 

                        **********


[DIAGNOSIS]
 
     Several logic errors in the EXE file writing code.
 

                        **********


[CURE]
 
     Rework the faulty routines, as shown  in  the  attached
FILCOM.   Note  that  this  edit  requires  edit  1110,  and
supersedes edits 774 and 776 if installed.

                        **********


[SYMPTOM]
 
 
 
 
     LINK can get an address check if all of  the  following
conditions are met:
 
     1.  The lowest code or data loaded occurs between  2000
         and 377777.
 
     2.  The program being loaded is small  enough  so  that
         LINK does not have to overflow to disk.
 
     3.  LINK is writing an EXE  file,  either  because  the
         program  is  too large to fit in memory, or because
         the user requested an EXE file with /SAVE.
 
 
     Also, LINK will fail to write out  the  correct  .JBVER
(location  137)  if  the  lowest  location loaded is 2000 or
above.
 
     If edit 776 has been installed, users will not see  the
above problems.  Instead, LINK will set up an incorrect page
0 (JOBDAT) when all of the following conditions are met:
 
     1.  LINK has overflowed to  disk,  either  because  the
         program  was too large to fit in memory, or because
         disk overflow was  forced  by  the  first  location
         loaded being above 400000.
 
     2.  The program being loaded is small  enough  so  that
         LINK  is  able  to  read all of it (from the lowest
         location loaded on  up)  back  in  at  the  end  of
         loading.
 
     3.  LINK is writing an EXE file.
 
 

                        **********


[DIAGNOSIS]
Digital Equipment Corporation       28-AUG-79    Page 258
PCO Log Report


 
     LINK always tries to write JOBDAT from  the  DY  buffer
(JOBPTR)  if  the lowest location loaded (LOWLOC) is 2000 or
above, on the assumption  that  disk  overflow  has  already
occurred.   However,  if the program is small enough so that
disk overflow has not occurred, and if disk overflow was not
forced  by  the lowest location being 400000 or higher, then
JOBDAT is in the LC area instead of the DY  area.   In  that
case,  LINK will pick up a zero address and try to write its
own JOBDAT into the EXE file.
 
     The missing .JBVER is due to an erroneous  output  IOWD
in the same area of code.
 
     If edit 776 has been installed, then an error  in  that
edit  will  cause  LINK to write out the page containing the
lowest location  loaded  as  the  JOBDAT  area,  instead  of
writing the correct JOBDAT area.
 

                        **********


[CURE]
 
    Do not try to get JOBDAT out of the DY area unless it is
really there, and correct the output IOWD.
 
     Note that this problem was fixed in LINK by edit  1132,
and  that  this  PCO  is  simply  a  small patch to fix this
particular problem without having to  install  all  of  edit
1132.   This edit will never appear in any future release of
LINK, since edit 1132 will be shipped instead.
 
     This  edit  also  supersedes   LINK   edit   776   (PCO
10-LINK-254),  which  was  an  incorrect  fix  for this same
problem.  Edit 776 should be removed before the installation
of this edit.

                        **********


[SYMPTOM]
 
 
 
 
LINK may lose up to 17 words of data in the program, replacing them
with zeros, if all of the following conditions are met:
 
     1.  The block of data being loaded crosses a page boundary  in
         the loaded program's address space
 
     2.  Data has already been loaded at higher  addresses  in  the
         same segment
 
     3.  The segment is paging to disk
 
 

                        **********


[DIAGNOSIS]
 
When the above conditions are true, LINK's window into the overflow
file  for the segment can become only one page long.  In this case,
an optimization made by edit 716 causes  LINK  not  to  expand  the
window, but just to leave it alone.
 
Those words in the block  following  the  page 263undary  are  then
stored past the end of LINK's window and lost.
 

                        **********


[CURE]
 
Change the optimization check to require the window to be at  least
two pages long if the request crosses a page boundary.

                        **********


[SYMPTOM]
 
 
 
 
     LINK can get an I/O to unassigned channel  error  while
writing  an  EXE file.  This will happen if the last word of
either the low or high segment (counting the symbol table if
one  is loaded) falls on the last word of a page, and if the
program being loaded is not so large that LINK needs to page
that segment to disk.
 

                        **********


[DIAGNOSIS]
 
     When LINK finishes writing its current  segment  window
into  the  EXE file, it tests to see if it has just finished
with the segment, and if not, assumes that  the  segment  is
paging  and  calls the paging routines to advance the window
to the next piece of the segment.  Unfortunately, the  check
to  see  if the segment is finished is off by one, so if the
segment  ends  on  the  last  word  of  a  page,  LINK  will
erroneously  think  that  it  has  not yet finished with the
segment, and call the paging routines to advance the window.
If  LINK  is  not  paging,  this  will  lead  to  an  I/O to
unassigned channel error, since the overflow files have  not
been opened.
 

                        **********


[CURE]
 
     Correct the test for end of segment, as  shown  in  the
attached FILCOM.

[PCO Write-up]



                        **********


[SYMPTOM]
 
 
 
 
     When loading a module containing mixed low segment  and
PSECT code, LINK will lose any low segment code appearing in
the source file before the first PSECT code.
 

                        **********


[DIAGNOSIS]
 
     A set of REL blocks (type 24) appear early in  a  PSECT
REL  file  to  describe  all  of the PSECTs appearing in the
module.  Unfortunately, one of the things LINK does when  it
sees  a  REL  block  type  24 is perform a set default PSECT
action, as if it had seen a REL block type 22.  If the first
code  (REL  block type 1) appearing in the REL file does not
load into a  PSECT, and  thus  is  not  preceded  by  a  set
default  PSECT  block, then LINK will end up loading it into
whatever PSECT was described by the last REL block  type  24
seen.   The  loaded  code  will then be overwritten when the
code that really belongs in that PSECT is loaded.
 

                        **********


[CURE]
 
     Change the processing of  REL  block  type  24  to  not
change  LINK's  default load PSECT (RC.CUR), as shown in the
attached FILCOM.

                        **********


[SYMPTOM]
 
 
 
 
     LINK can get an illegal memory reference when loading a
FORTRAN program.  This can happen if the FORTRAN program has
a data element in a COMMON block and an ENTRY  of  the  same
name,  and  if  the  program  is  being loaded without local
symbols (default on TOPS-10).
 

                        **********


[DIAGNOSIS]
 
     In this case, FORTRAN generates three adjacent RADIX-50
symbols  in  a REL block type two in the REL file:  a global
definition for the ENTRY name, a local  definition  for  the
COMMON  data element name, and an external request that adds
the base of the COMMON block to the previous symbol,  namely
the  COMMON  data element name.  When LINK sees the external
request, it checks to see if the symbol it is trying to  fix
up  is  the  same  as  the  last  symbol  loaded, and if so,
processes the fixup.
 
     Unfortunately, when LINK is  not  loading  locals,  the
last  symbol loaded when the external request is seen is the
global definition for the ENTRY name.  Since this symbol has
the  same name as the object symbol of the external request,
LINK thinks all is OK and adds the base of the COMMON  block
to  the  value  of  the entry name.  It then gets an illegal
memory  reference  when  attempting  to   track   down   all
references to the symbol it just defined and fix them up.
 

                        **********


[CURE]
 
     When not loading locals, clear the pointer to the  last
symbol  loaded  every  time  a  local  is  skipped,  so  any
following symbol fixups will be ignored.

                        **********


[SYMPTOM]
 
 
 
 
     After edit 767 is installed, LINK can write  EXE  files
that  contain  extra pages after the end of the low segment.
This can only happen if the lowest  location  loaded  is  at
400000 or higher, e.g.  if PSECTs are being used.
 

                        **********


[DIAGNOSIS]
 
     The  EXE  file  writer  writes  out  the  entire   area
containing  the low segment, on the assumption that the area
contains only enough room  to  hold  the  segment.   If  the
lowest  location  loaded  is  above 400000, however, the low
segment area can  end  up  being  larger  than  the  minimum
necessary to hold the segment.
 

                        **********


[CURE]
 
     Move the EXE file writer's check for end of segment  to
before the check for end of segment area.
 
     This edit is an extract of part of edit 1132,  and  has
been made only to keep users who wish to fix this particular
problem from having to install all of edit 1132.  This  edit
will  not  be  present  in any future release of LINK, since
edit 1132 will be present instead.  Note also that this edit
supercedes  edit  1136 (another extract of edit 1132), which
should  be  removed  if  it  has  been  installed  prior  to
installing this edit.

[SYMPTOM]
 
 
 
 
     Various, including looping, losing the  runtime  symbol
table,  and  writing  a very large overflow file.  This will
only happen if a /SET:.HIGH. switch is  used  after  a  high
segment  already  exists  to change the current value of the
high segment relocation counter, and only if edit  1132  has
been installed.
 

                        **********


[DIAGNOSIS]
 
     An  error  in  edit  1132  caused  the   high   segment
relocation  counter  to  be  pointed to the low segment if a
/SET switch is ever used to change its value.  This confuses
the rest of LINK tremendously, leading to various errors.
 

                        **********


[CURE]
 
     Never cause the  high  segment  relocation  counter  to
point to the low segment.

                        **********


[SYMPTOM]
 
 
 
 
     The runtime symbol table can end  with  a  symbol  name
rather  than  a module name.  This happens if the user types
/NOINITIAL and then some switch that defines a symbol  (such
as /SET or /COMMON) before loading anything.
 

                        **********


[DIAGNOSIS]
 
     In this case, the switch processing  routines  add  the
symbols to the LS area before JOBDAT or any other module has
been loaded.  When the LS area is scanned backwards to build
the  runtime  symbol  table, the last thing seen is a symbol
rather than a module name.
 

                        **********


[CURE]
 
     If LS.ADD is called  to  insert  a  symbol  before  any
module  names  have  appeared,  generate  a fake module name
using the name of the symbol being inserted.

                        **********


[SYMPTOM]
 
 
 
 
If LINK must run the loaded program from an .EXE file  (either  too
large  or  /SAVE/EXECUTE  specified), PA1050 is left in memory even
though the loaded program does not use TOPS-10 UUOs.
 

                        **********


[DIAGNOSIS]
 
PA1050's simulation of the RUN  UUO  does  not  clear  away  PA1050
itself, under the assumption that pages 700 and up do not matter to
user programs.
 

                        **********


[CURE]
 
Rewrite LINK's run code to not use the RUN UUO, but to do the  work
itself.   Unmap  all  of  memory unless /DEBUG:DDT is specified, in
which case do not unmap UDDT.
 
Note that since universal files are changed as  a  result  of  this
edit,  all  of  the  LINK  sources  must  be  recompiled  following
installation of the edit.

                        **********


[SYMPTOM]
 
 
 
 
When LINK edit 1144 is  installed,  the  EXEC's  DEBUG  command  or
explicit  specification  of  /DEBUG:DDT to LINK does not set up the
DDT symbol table pointers or load local symbols.  This only happens
if  LINK  can load the program directly into memory (i.e., does not
have to write an .EXE file).
 

                        **********


[DIAGNOSIS]
 
The method of determining whether DDT was mapped in as a result  of
/DEBUG:DDT  was  changed by edit 1144, but the load-and-go code was
not modified to reflect the change.
 
Also, one too many intructions were removed from the code  to  load
DDT,  causing  LINK  to  forget  to load local symbols for the next
file.
 

                        **********


[CURE]
 
Check properly whether DDT was loaded, and force loading of  locals
for the next file.

                        **********


[SYMPTOM]
 
 
 
 
Various symptoms are possible.  Some examples are:
 
     1.  When loading a PSECTed program  with  large  gaps  between
         PSECTs,  LINK  will  create  the  pages in the gaps if the
         program is loaded into memory but not if  the  program  is
         written with /SAVE.
 
     2.  `?LNKRME REMAP error' results if the high  segment  origin
         of  a  two-segment  program is set lower than the combined
         length  of  LINK's  low  segment  and  the  program's  low
         segment.
 
 

                        **********


[DIAGNOSIS]
 
 
     1.  LINK cannot in  general  load  a  program  sprinkled  with
         non-existent  pages.   There  is  only monitor support for
         LINK to set up non-existent pages below the  high  segment
         (the   REMAP   UUO).   Programs  with  non-existent  pages
         elsewhere must be written to an .EXE file.
 
     2.  In this case, LINK is requesting that the REMAP  UUO  move
         the  prospective  high segment down.  This is not possible
         since this would overlay the low segment.
 
The common problem is that LINK's checks for deciding to  write  an
.EXE   file   instead  of  loading  the  program  into  memory  are
insufficient.
 

                        **********


[CURE]
 
Digital Equipment Corporation       28-AUG-79    Page 341
PCO Log Report


Restructure the code in LNKXIT so that all checks used to determine
whether to load the program or write an .EXE file are in one place.
Then add the above cases to the checks.  Since these cases are more
general than the current condition of not enough memory, change the
LNKNCL and LNKNCX messages to LNKPCL and LNKPCX.
 
The effect of this edit  is  to  cause  LINK  to  force  .EXE  file
generation  for  those cases in which LINK cannot leave the program
in memory.
 
There are several points to consider when installing this edit.
 
     1.  The FILCOMs show the edit installation assuming that edits
         1113  and  1132 were previously installed.  If this is not
         the case, simply ignore the references to these edits.
 
     2.  The majority of  the  changes  in  LNKXIT.MAC  are  simply
         moving  code around to centralize the checks for a complex
         program.   The  FILCOM  therefore   contains   information
         indicating  how  to move the code around, so that deleting
         and retyping of the moved code should not be necessary.

                        **********


[SYMPTOM]
 
 
 
 
     LINK  can  write  an  incorrect  EXE  file  under   the
following conditions:
 
     1.  The lowest location loaded is at 400000 or above.
 
     2.  The lowest location loaded  is  not  loaded  first,
         i.e., the load is not monotonic.
 
     3.  LINK is paging to disk.
 
     4.  The last location loaded  is  fairly  near  to  the
         first location loaded.
 

                        **********


[DIAGNOSIS]
 
     Under the above conditions, the lowest location  loaded
will  be  in  the  middle  of  the  LC area window.  If that
happens, LINK will move the bottom of the LC  window  up  to
point  to the lowest location loaded, but will not bother to
adjust the size of the LC area or the top of the window,  so
the  physical  and virtual limits of the LC area disagree as
to how  large  the  area  is.   This  disagreement  violates
assumptions made in the EXE file writer.
 

                        **********


[CURE]
 
     When moving up the bottom of the virtual  window,  move
up  the  bottom  of the area as well by giving the bottom of
the area to the DY area.

                        **********


[SYMPTOM]
 
 
 
 
LINK gives the ?LNKFRE message for the  log  file  if  all  of  the
following conditions are met:
 
     1.  The user's default path is in an SFD.
 
     2.  A log device has been  assigned  the  logical  name  LOG:,
         requesting that LINK write a log file.
 
     3.  The /LOG switch is given to LINK to give the  log  file  a
         name.
 
 

                        **********


[DIAGNOSIS]
 
If a log file is requested at LINK start-up time by assigning a log
file device a logical name of LOG:, LINK begins the log file with a
temporary name of nnnLNK.LOG.  If a /LOG switch is later  specifed,
LINK  remembers  to  rename the log file to the correct name at the
end of loading.
 
Unfortunately, LINK's initialization routines create  the  file  by
hand  but  do  not  save the file's path over the ENTER UUO.  Thus,
when LINK attempts to find the file later with the RENAME  UUO,  it
uses  the junk left by the previous ENTER UUO.  This causes LINK to
not find the file.
 

                        **********


[CURE]
 
Change the log file initialization routines to use LINK's own  file
routines  instead  of  doing the work by hand.  These routines save
the path pointer over the ENTER UUO, allowing the subsequent RENAME
UUO to find the log file again.

     Overlaid programs may fail with an illegal UUO or other
error  indicating  that zeros were loaded where code or data
should have gone.  This will only happen after edit 1132 has

     The new EXE file writer looks at RC.HL in the RC  block
to  determine  how  much  to save.  The overlay code in LINK
does not bother to keep it up to date.
 

                        **********

     Keep  RC.HL  up  to  date  in  the  overlay  processing

[SYMPTOM]
 
 
 
 
     If a PSECT header  REL  block  (type  24)  contains  an
invalid  PSECT  index, LINK will loop, get an illegal memory
reference, or generate a bad program.
 

                        **********


[DIAGNOSIS]
 
     There is no consistency check.  This is a common error,
because  a  PSECT  index  of zero is sufficient to make LINK
fail.
 

                        **********


[CURE]
 
     Give a LNKIPX error in this case.  Note that this  edit
requires edit 1137 to LINK.

                        **********


[SYMPTOM]
 
 
 
 
     There are several problems with the PSECT  Break  block
(REL block type 24), as follows:
 
     1.  LINK re-arranges the PSECT indices for  the  module
         being  loaded based on the order of the PSECT Break
         blocks in the REL file, so that if the PSECT  Break
         blocks  are  not  put  into  the REL file sorted by
         PSECT index, then any following  Set  PSECT  blocks
         (type  22)  or  Polish  blocks (type 11) containing
         PSECT indices will get the wrong PSECT.
 
     2.  LINK requires a PSECT Break block with a blank name
         to be the first one seen for each module.
 
     3.  Unlike all of the other REL blocks  that  reference
         defined PSECTs, the PSECT Break block takes a PSECT
         name instead of a PSECT index.
 
     4.  The  PSECT  Break  block  inadvertently  takes  the
         action of a Set PSECT block (i.e., sets the default
         PSECT) during its processing.
 
 

                        **********


[DIAGNOSIS]
 
     The PSECT Break block used to do something else  in  an
early  implementation  of  PSECTs.   It  was  only partially
converted to the final design.
 

                        **********


[CURE]
 
     Re-work the PSECT Break processing code in LINK.   This
Digital Equipment Corporation       28-AUG-79    Page 394
PCO Log Report


REL  block  will now expect a PSECT index instead of a name,
although a name will still work for compatability.

[SYMPTOM]
 
 
 
 
     PSECT .HIGH.  is not equivalent to TWOSEG.  If  a  user
tries to specify PSECT .HIGH., LINK gets internal errors.
 

                        **********


[DIAGNOSIS]
 
     The REL file input routines add 400000  to  relocatable
quantities  from this PSECT twice:  once because they are in
a PSECT that starts at 400000, and once because they are  in
the high segment.
 

                        **********


[CURE]
 
     Re-work the REL file input routines  (RB.1)  to  handle
this  case  correctly.   As  part of this edit, preserve the
PSECT attributes for the .HIGH.  PSECT.

[SYMPTOM]
 
 
 
 
     The program break in the end block (REL block  type  5)
is  relocated  with respect to whatever PSECT is the current
default.  It should be relocated with respect to .LOW..
 

                        **********


[DIAGNOSIS]
 
     The T.5 routine calls  the  standard  relocating  input
routines, which relocate with respect to the current PSECT.
 

                        **********


[CURE]
 
     Clear the current  PSECT  before  reading  the  program
break.

                        **********


[SYMPTOM]
 
 
 
 
     Defining an undefined symbol with DDT can cause DDT  to
destroy  random low addresses.  Examination of the undefined
symbol table pointed to by .JBUSY=117 will  reveal  additive
fixups to the locations destroyed.
 
     This will only happen if the symbol  defined  with  DDT
was  used  in  the  source  program  as  part  of  a  Polish
expression.
 

                        **********


[DIAGNOSIS]
 
     LINK is  putting  out  Polish  requests  for  undefined
symbols as if they were additive fixups, with the address to
be added to as the offset to the  Polish  string  in  LINK's
internal  FX  area.   It is doing this because it checks for
some things that  it  doesn't  know  how  to  put  into  the
undefined  table, and avoids them.  When Polish was added to
LINK, this check was not extended, so LINK thinks Polish  is
OK to put out.
 

                        **********


[CURE]
 
     Instead of checking for the things  LINK  doesn't  know
how to put into the undefined table and avoiding them, check
for the few things that LINK does know how to do  and  avoid
everything else.

[SYMPTOM]
 
 
 
 
     UDDT cannot find any symbols when a program  is  loaded
with  both  /SAVE  and  /DEBUG in the same command string to
LINK.  Also, the DDT command does not work if the  resulting
EXE  file  is later set up with a GET command.  Instead, the
user will get an illegal instruction at 770000.
 

                        **********


[DIAGNOSIS]
 
     LINK does not set up DDT's symbol table pointers if  is
creating  an  EXE  file.   Instead, it (incorrectly) sets up
.JBDDT.
 

                        **********


[CURE]
 
     Set up the right things at the right times.  Note  that
this  edit  is  an  extract  of edit 1144, and should not be
installed if edit 1144 has been installed.  This  edit  will
not  be  present in any future release of LINK, because edit
1144 will be shipped instead.

                        **********


[SYMPTOM]
 
 
 
 
     With edit 1155 installed, users must specify an  origin
for  the  .HIGH.  psect.  If they don't, LINK fails with the
LNKRPN message.
 

                        **********


[DIAGNOSIS]
 
     LINK sets the flags  in  the  .HIGH.   block  from  the
user's  input.   If  the user didn't specify an origin, then
LINK marks .HIGH.  as not having a known origin.  This is OK
for  most  psects,  but LINK will supply a default value for
.HIGH.'s origin if  the  user  didn't  specify  one,  so  it
doesn't really apply to .HIGH..
 

                        **********


[CURE]
 
     Don't set the  relocatable  psect  bit  in  the  .HIGH.
descriptor block.

                        **********


[SYMPTOM]
 
 
 
 
     Some symbols may appear in the map and the runtime  DDT
symbol  table  with  incorrect values, typically zero.  This
will only happen to symbols that appear late  in  the  load,
and that are defined in terms of other external symbols.  In
addition, bit 11 of some word in the  program  being  loaded
may get zeroed.
 
     This can only happen under the following circumstances:
 
     1.  The user has requested LINK to print a map.
 
     2.  The program being loaded is so large that LINK  has
         to overflow its LS area to disk.
 
This error is very dependent on memory layout,  and  can  be
made  to  disappear by playing with the /MAXCOR or /HASHSIZE
switches, or by varying the job's virtual limit.
 

                        **********


[DIAGNOSIS]
 
     If the LS area is paging to disk, then LNKMAP reads  it
into  an  internal  window  a  piece  at  a time in order to
process it and print the map.  If  the  last  partial  piece
does  not  take  up  the entire window, then LINK zeroes the
unused part and returns it to free space, so it can be  used
for other purposes.  Unfortunately, the test to check for an
unused part is wrong, so LINK always thinks  that  at  least
the last page of the window is unused.  If the last piece of
the LS  area  exactly  fills  the  window,  then  LINK  will
erroneously  zero  the  first  page of the next area (the FX
area).
 
     Clearing the first page of the FX area  can  obliterate
some  symbol fixups that were destined for the last piece of
the LS area, resulting in symbols with incorrect  values  in
the  map  and  the  DDT  symbol table.  In addition, if LINK
Digital Equipment Corporation       28-AUG-79    Page 434
PCO Log Report


attempts to process an all-zero block as a valid  fixup,  it
will  clear  the undefined bit (1B11) in what it thinks is a
triplet in the LS area, but which is actually some  word  of
the program being loaded.
 

                        **********


[CURE]
 
     Correct the test so that LINK will not try to  zero  or
return  anything if the last piece of the LS area completely
fills the window.

[PCO Write-up]



                        **********


[SYMPTOM]
 
 
 
 
When  loading  programs  that  contain  complicated  symbol   fixup
requests,  various  internal  errors (such as illegal memory reads)
may occur.  This will happen only when not loading  local  symbols,
or  when  local  symbols  have been removed from the .REL file (via
/NOLOCAL to MAKLIB).
 

                        **********


[DIAGNOSIS]
 
This problem is caused by the way that fixups to partially  defined
symbols  are  done.  A common case is a local symbol defined as the
value of an external symbol plus a constant.  This  is  handled  by
specifying  a  word pair in a symbol .REL block (type 2) that first
defines the local with the value of the constant.  Then IMMEDIATELY
FOLLOWING  this,  another  word  pair  requests the external with a
fixup request to the previous local.  The fixup is  only  valid  if
the  symbol  requested  for fixup was the last symbol definition in
the .REL file.  If it was not, the request should be ignored.
 
Unfortunately, if LINK is not loading locals, one of these  special
fixup  requests  may `see' a very old symbol as the last loaded one
that just happens to match.  LINK  then  believes  that  the  fixup
should be done rather than ignored, usually leading to disaster.
 

                        **********


[CURE]
 
Whenever a check of a  special  fixup  request  matching  the  last
symbol  loaded fails, forget what the last loaded symbol was.  This
is valid since  the  rule  that  the  symbol  definitions  must  be
adjacent cannot be met until another symbol is actually loaded.

                        **********


[SYMPTOM]
 
 
 
 
     If a Polish block does  not  contain  a  default  PSECT
index  in  the  first halfword, but does contain an embedded
PSECT index later on, LINK  will  take  the  embedded  PSECT
index  as  the  default  PSECT  index.   This is actually an
illegally formatted Polish block, but a plausible one for  a
new compiler to generate.
 

                        **********


[DIAGNOSIS]
 
     LINK identifies the default PSECT for a Polish block as
the   first   set   PSECT  byte  seen  in  the  block.   The
documentation states that a Polish block  that  uses  PSECTs
must have a set PSECT byte as the first half word.
 

                        **********


[CURE]
 
     Identify the default PSECT  for  the  Polish  block  by
checking  the first byte of the Polish block to see if it is
a set PSECT byte, and snarfing it if so.  If  not,  remember
that this Polish block is not allowed to contain PSECTs, and
give the LNKIPX error if a set PSECT byte is seen  later  in
the block.

                        **********


[SYMPTOM]
 
 
 
 
There are several problems  with  LINK's  memory  management
near  the end of loading, when LINK is setting up the user's
program in memory.  Note that the errors  listed  below  can
only  happen  if  LINK  is  NOT generating an EXE file.  The
specific symptoms fixed by this edit are as follows:
 
     1.  LINK can leave zeros in place of a large portion of
         the  user's  high segment when it leaves the loaded
         program set up in memory.  This error is much  more
         likely  if  the command string to LINK contains the
         /MAXCOR switch.
 
     2.  If the low segment ends with a module that declares
         a  larger  program  break  than it actually loaded,
         then LINK may load the  program  with  insufficient
         memory  to  run.   This  will  cause illegal memory
         references when the program runs.
 
     3.  LINK can get an illegal memory reference  near  the
         end of loading.  Closer inspection will reveal that
         the failure occurred on a BLT instruction.
 
     4.  After edit 1146 has been installed,  LINK  is  very
         slow  loading  small  programs  on TOPS-20.  It can
         also be slow on TOPS-10 if  the  user  specified  a
         /CORE  switch  with  an argument which was so large
         that LINK was forced to go virtual.
 
 

                        **********


[DIAGNOSIS]
 
     1.  If LINK decides that it has enough memory to  leave
         the  program  loaded  into memory, it will allocate
         two large arrays, one for the low segment  and  one
         for  the  high  segment.  To fill these arrays with
         the program,  it  will  BLT  that  portion  of  the
Digital Equipment Corporation       28-AUG-79    Page 453
PCO Log Report


         program already somewhere in memory into its proper
         place in the array(s).  If either segment is paging
         to  disk, then LINK will fill the rest of the array
         for that segment by reading the data  in  from  the
         overflow file.
 
         The problem arises when LINK  had  to  overflow  an
         area  to  disk earlier in the load, but now decides
         that it will all fit into memory after all (this is
         unlikely   unless   the   user   has   artificially
         restricted the amount of memory available  to  LINK
         via the /MAXCOR switch).  In this case, the portion
         of the segment currently in memory is just a window
         into  the  overflow  file which contains the entire
         segment, and LINK will  try  to  move  this  window
         buffer   into   the  array  at  the  proper  place.
         Unfortunately, the window is  usually  pointing  to
         the  very  end  of  the overflow file, and contains
         several pages that are actually off the end of  the
         file.   This causes a problem because the array was
         allocated based on the actual size of the  overflow
         file,  and  does not provide for the extra pages in
         the window buffer.  When LINK  tries  to  move  the
         entire  window  into the segment array, it will BLT
         past the end of the  array  and  overwrite  several
         pages  following the array, usually either the next
         segment or illegal memory.
 
     2.  LINK is not taking the extra memory into account in
         its  decision to load the program into memory or to
         write an .EXE file.
 
     3.  When LINK allocates an array for the program's high
         segment  as described in (1), it allocates the size
         based on the  entire  size  of  the  high  segment,
         including  any area allocated but not loaded at the
         end of the high segment.  If not  paging  the  high
         segment  to  disk,  it  then  moves the entire high
         segment into its new area with a  BLT  instruction,
         based  on the size of the new area.  Unfortunately,
         the old area that contained the  high  segment  did
         not  include the non-loaded area at the end, so the
         BLT can be moving  more  data  than  the  old  area
         contained.   If  the  old  area was near the top of
         memory (which it usually will be), this excess will
         result in an illegal memory reference.
 
         Illegal memory references can also be  produced  by
         problem (1).
 
     4.  After LINK has finished  moving  both  segments  to
Digital Equipment Corporation       28-AUG-79    Page 454
PCO Log Report


         their  new homes and compressing out the free space
         between them, it tries to reduce the  size  of  the
         low  segment  to  the minimum necessary, then clear
         the last partial-page gaps  remaining  between  the
         segments.   Unfortunately,  the  code to reduce the
         size of LINK's low  segment  is  not  even  reached
         unless the program being loaded has a high segment,
         and even then the test to decide whether to  reduce
         the  low  segment  size  is backwards, so LINK will
         never actually shrink.   This  means  that  it  can
         potentially  end  up  clearing  many "extra" pages,
         instead of just a few partial pages.
 
         This extra clearing will not cause much problem  on
         TOPS-10  systems,  since  the  low  segment usually
         isn't too much bigger than it needs to  be  (unless
         forced  to  be  so  by  the  user  with /CORE).  On
         TOPS-20, however, LINK's low segment starts out  at
         maximum  size,  and  stays  that way throughout the
         load.  Under these conditions, this BLT will  clear
         about  300  extra pages, which can more than triple
         the time needed to load a small program.
 
 

                        **********


[CURE]
 
     1.  Only move the valid portion of  the  window  buffer
         into the segment array.
 
     2.  Modify the memory check to include this case.
 
         Note however that if execution was  also  requested
         in the load but there is still not enough memory to
         run the program, then the monitor message  `?nP  of
         core  needed'  will result.  This can only be fixed
         by increasing the  job's  physical  and/or  virtual
         limits.
 
     3.  Allocate the new high segment array based  only  on
         the  portion  of  the  high segment before the last
         non-loaded part.  This is already the way that  the
         low segment allocation is done.
 
     4.  Fix the flow of control to always get  to  the  low
         segment  reduction check, and then fix the sense of
         the check.

all  in  the  same  section of code, and could not have been
easily split out into different edits.

                        **********


[SYMPTOM]
 
 
 
 
     Even after edit 1146 is installed, the TOPS-10  version
of  LINK  will  not  say LNKPCL and write an EXE file if the
user requests a write-enabled high segment or a write-locked
low segment.  The monitor group suggests that these might be
implemented some day, and requests that  LINK  not  disallow
such a construct.
 

                        **********


[DIAGNOSIS]
 
     Edit 1146 didn't think PSECT attributes  were  relevant
to TOPS-10.
 

                        **********


[CURE]
 
     Remove the TOPS-20 conditional,  and  special-case  the
TOPS-10 high segment.

                        **********


[SYMPTOM]
 
 
 
 
     The routines in LNKXIT.MAC having to do with generation
of  the  runtime  symbol  table  and  the  associated memory
management are some of the worst in  LINK.   They  are  very
difficult  to  understand  and maintain, are poorly written,
and have been the source  of  many  edits  to  correct  bugs
reported  via  SPRs  (including 8 new edits in the year that
LINK v4 has been out).
 
     This PCO is a re-work of that section of LNKXIT.MAC  in
LINK   in   an   attempt  to  improve  its  reliability  and
maintainability.  Some of the specific  problems  that  have
been fixed by this edit are as follows:
 
     1.  If LINK does not have sufficient room to generate a
         complete  runtime symbol table (and thus issues the
         LNKISS message), then the table generated  will  be
         incorrect.   The last word of the table will not be
         a module name,  and  there  will  therefore  be  no
         linked list of module names in the symbol table.
 
     2.  Field image LINK will not allocate a patch area  if
         the  user  asks (via /SYMSEG) for the symbols to go
         into a psect that is empty except for the  symbols.
         Edit  772  fixed  this  problem, but introduced the
         problem  that  the  contents  of  .JBUSY  will   be
         incorrect  if  the  program  contains any undefined
         symbols.   Edit  1121  fixed  this   problem,   but
         re-introduced the original problem.
 
     3.  LINK ignores other psects and the /UPTO switch when
         writing  the  undefined  symbol  table.  This means
         that the undefined  table  can  overwrite  whatever
         follows  it,  or can cause LINK to blow up if there
         are so many undefined symbols  that  the  undefined
         symbol table extends beyond 777777.
 
     4.  LINK can generate a bad runtime  symbol  table  for
         some  links  of an overlaid program if loading in a
         restricted amount of memory.

     5.  The contents of the left half of .JBCOR  (the  last
         location   loaded   with   non-zero  data)  can  be
         incorrect if the symbols are appended to  a  psect.
         The symbols will not be counted as non-zero data.
 
     6.  Any code or data immediately beyond the end of  the
         runtime  symbol  table  can be lost up to the first
         page boundary beyond the end of the  symbol  table.
         This  can  only occur if the segment into which the
         symbol table is being inserted  has  overflowed  to
         disk.
 
     7.  The segment containing the symbol table will be too
         long  if  the  program  contains  undefined symbols
         requiring additive fixups, and if the  symbols  are
         appended  to a psect.  The segment will be extended
         by  two  words  for  each  additive  fixup  request
         appearing in the undefined table.
 
     8.  After edit 1132 has been installed, LINK  will  get
         an  I/O  error  to  its  low  segment overflow file
         (nnnLLC.TMP) if the LC area is overflowing to disk,
         LINK  is  writing  an EXE file, and location 777777
         has been loaded with non-zero data (e.g., the  last
         word of the symbol table).
 
     9.  LINK will write an incorrect, very small .SYM  file
         if  the  user  asks for a new-style symbol file via
         /SYFILE:TRIPLET, and LINK's internal  LS  area  has
         NOT overflowed to disk.
 
    10.  LINK will not allocate a patch area in an  overlaid
         program,  despite  code in LNKOV1 which attempts to
         do so.  Even when this is fixed, the runtime symbol
         table LINK generates for overlaid programs does not
         contain the PAT..  module or symbol, so  the  patch
         area cannot be found.
 
    11.  The left half of the value word of the first module
         in  the runtime symbol table will contain zero.  It
         should contain the negated number of words  in  the
         part of the symbol table describing that module.
 
    12.  After edit 770 has been installed, the contents  of
         .JBUSY  and  possibly other JOBDAT locations can be
         incorrect.  This will only happen  if  the  program
         being  loaded contains undefined symbols, a runtime
         symbol table is being generated, and  the  LC  area
         overflows to disk at the wrong time.
 
    13.  When LINK is writing the runtime symbol  table,  it
Digital Equipment Corporation       28-AUG-79    Page 477
PCO Log Report


         thinks  it  has  run  out of room and truncates the
         table one location before  it  has  to.   In  other
         words,  it  always  leaves  a  zero  word after the
         runtime symbol table, even if it  has  to  truncate
         the table to do so.
 
    14.  After edit  1132  has  been  installed,  LINK  will
         truncate  the runtime symbol table too soon or skip
         writing it entirely in certain instances  of  psect
         overlap.   The  cases  that fail occur when another
         psect starts in the middle of the  psect  to  which
         symbols are being appended.
 
    15.  If LINK  comes  close  to  running  into  the  high
         segment  when  writing the runtime symbol table, it
         will stop and truncate the table 100  words  before
         it has to.  It will not do this if the symbol table
         threatens  to  overlap  any  psect  but  the   high
         segment.
 
    16.  The /UPTO switch can cause problems when loading an
         overlaid program.  LINK tries to ignore this switch
         for overlaid programs,  since  the  runtime  symbol
         table  is placed at runtime by the overlay handler.
         However, the switch is not completely  ignored,  so
         that LINK will stop generating symbols for any link
         whose symbol table size exceeds the argument to the
         /UPTO switch.  For example, /UPTO:10 will guarantee
         that the overlay file will not contain more than 10
         words of symbol table information for any link.
 
    17.  LINK will leave a temporary file  names  nnnLAS.TMP
         in  the  user's  default  path  if  the  AS  (Algol
         symbols) area  overflows  to  disk,  but  the  user
         prevents  generation  of  an Algol .SYM file (e.g.,
         via /SYFILE:RADIX50).
 
    18.  The LNKXIT module is much larger than it  needs  to
         be,  and  frequently reveals bugs related to memory
         management  when  generating  the  runtime   symbol
         table.
 
 

                        **********


[DIAGNOSIS]
 
     1.  When LINK runs out of  room  to  write  the  symbol
         table, it just stops, without any attempt to insure
Digital Equipment Corporation       28-AUG-79    Page 478
PCO Log Report


         that the table is terminated by a module name.
 
     2.  The same register  (P2)  is  assumed  to  hold  two
         different numbers, depending on whether the program
         being    loaded    contains    psects    or    not.
         Unfortunately, some places still want the non-psect
         number, even when psects are  being  loaded.   This
         doesn't  work,  since  the  number  is  not  in the
         register, and was never stored anywhere else.
 
     3.  The undefined symbol table  writer  does  not  call
         SYMOUT  (which  checks  psect  bounds  and  /UPTO).
         Instead, it simply stores the symbol table data  by
         hand, without making any of the necessary checks.
 
     4.  When LNKOV2 calls LSLOOP in LNKXIT  to  generate  a
         runtime symbol table for each link, it insures that
         the LC area has not overflowed to  disk.   However,
         if  the  overflow occurs during LSLOOP's execution,
         LNKOV2 will ignore it and take  whatever  data  has
         not  been  paged  out  as the entire runtime symbol
         table for the link.
 
     5.  LINK does not update its internal  pointer  to  the
         last   location   containing   non-zero  data  when
         appending the runtime  symbol  table  to  a  psect.
         This is apparently because the number needed is not
         conveniently available at that point in LNKXIT.
 
     6.  LINK assumes that it is appending the symbol  table
         to the end of a segment, and that there can thus be
         nothing in the overflow file for the segment beyond
         the  symbol  table.   It  therefore writes pages of
         symbols out to the overflow file without trying  to
         save   the   old   contents  of  the  pages.   This
         assumption fails when using psects, since the psect
         to  which  the  symbol  table is being appended can
         appear anywhere within the segment.
 
     7.  LINK estimates the length of  the  undefined  table
         before  writing  it,  and  if  the  table  is being
         appended to  a  segment,  it  updates  the  segment
         length  by  the  size  of the table.  This estimate
         does not include additive fixups, however, and when
         LINK   finds   one  of  these,  it  goes  back  and
         increments   the    segment    length    by    two.
         Unfortunately,  the  segment  length  should not be
         incremented when the undefined  symbols  are  being
         appended  to  a psect in the middle of the segment,
         so  the  segment  length   is   being   incorrectly
         incremented in this case.
Digital Equipment Corporation       28-AUG-79    Page 479
PCO Log Report


 
     8.  The .EXE file writer assumes that  the  pointer  to
         the first free word beyond the program is a pointer
         to  the  last  used  word  of  the   program   when
         processing  overflow files.  This causes it to call
         the paging routines  with  a  request  for  a  page
         beyond  777 if the last used word in the program is
         777777.  This large page number causes  the  paging
         routines  to  issue an invalid IN UUO, resulting in
         an I/O error.
 
     9.  When the LS area has not overflowed to  disk,  LINK
         deletes  it  as  it scans through it generating the
         runtime symbol table.  Unfortunately, the  contents
         of  this  area are needed for the sixbit .SYM file,
         which is not  generated  until  after  the  runtime
         symbol table has been completed.
 
    10.  LNKOV1 does not update enough pointers to  get  the
         patch  area allocated.  Even if it did, the code to
         generate the PAT..   symbol  is  not  reached  when
         generating   the   symbol  table  for  an  overlaid
         program.
 
    11.  LNKXIT's internal pointer to the last  module  name
         written   to  the  symbol  table  (TTLPTR)  is  not
         initialized correctly before generating the  symbol
         tables for overlay links.
 
    12.  Edit 770 removed a necessary call to CHKPAG,  which
         checks  to see if JOBDAT has been paged out, and if
         so, puts it into a buffer in the DY area.  If  this
         is  missed,  LINK will store into what it thinks is
         JOBDAT, but is actually some random place in LINK's
         low segment.
 
    13.  The truncation check is off by one.
 
    14.  LINK assumes that the psect with  the  next  higher
         psect  origin  beyond  the one to which symbols are
         being appended is the  one  to  use  as  a  cutoff.
         However, if the next higher psect starts within the
         psect to which symbols  are  being  appended,  then
         LINK  will think that it has run out of room before
         writing anything.
 
    15.  There was apparently some attempt  to  implement  a
         100  word  gap area after the runtime symbol table.
         However, the implementation was  not  complete,  so
         the  relevant  code is only reached if the limiting
         psect is .HIGH..
Digital Equipment Corporation       28-AUG-79    Page 480
PCO Log Report


 
    16.  Since the runtime symbols for an  overlaid  program
         are  put into the overlay file and not into memory,
         LNKXIT loads them into a  dummy  area  starting  at
         address  0.   However,  the  symbol deposit routine
         still looks at /UPTO, so  it  will  stop  when  its
         internal   "fake"   address   reaches   the   /UPTO
         parameter.
 
    17.  LINK never tries to delete the nnnLAS.TMP file.  It
         will  only go away if is renamed to be a .SYM file,
         which will only happen if the user wants  an  Algol
         .SYM file.
 
    18.  LNKXIT does much of its own memory  management  and
         disk  overflow  handling  when creating the runtime
         symbol table.  This causes LNKXIT to  be  huge  and
         complex,  and  leads to bugs when it does decide to
         call LNKCOR for some  action,  because  the  memory
         management  data  base  maintained by LNKCOR is not
         always updated correctly when LNKXIT does things by
         hand.
 
 

                        **********


[CURE]
 
     Re-work the runtime symbol generation code  in  LNKXIT,
maintaining  existing  routines or code where possible.  The
specific fixes to each problem (where applicable) are listed
below.
 
     1.  Reserve the last two words of the symbol table  for
         the  last  module name, and, if the symbol table is
         about to be truncated, skip ahead  until  a  module
         name  is found, so that the table can be terminated
         properly.
 
     2.  Re-work that section of  code  so  that  everything
         always  looks  like  a  psect,  thus  removing many
         special case checks and the need  to  carry  around
         two sets of numbers.
 
     3.  Generalize SYMOUT  so  that  the  undefined  symbol
         table  generator  can  call it, and then make every
         place that wants to write something to  the  symbol
         table go through it.
 
Digital Equipment Corporation       28-AUG-79    Page 481
PCO Log Report


     4.  Check for the LC  area  overflowing  to  disk  when
         generating  the  symbol  table for an overlay link,
         and complain to the  user  of  insufficient  memory
         (the ?LNKCEF error) if this occurs.
 
     5.  Move the update of  .JBCOR  to  after  all  of  the
         symbols  have  been  written,  so  that the data is
         always  available,  and  so  that  the  psect   and
         non-psect  cases  need  not  be  distinguished  and
         handled differently.
 
     6.  Check the size of the overflow file,  and  read  in
         any  valid  data  beyond  the  symbol  table before
         generating the symbol table.
 
     7.  Don't update the segment  length  until  after  the
         entire  symbol  table has been written, so that the
         exact length can be computed.
 
     8.  Subtract one from  the  first-free  pointer  before
         using it as a last-used pointer.
 
     9.  Do not delete the LS area until  after  the  sixbit
         .SYM file (if any) has been written.
 
    10.  Allocate the area, and make the code  that  inserts
         PAT..   into  the symbol table a subroutine, so the
         overlay symbol table generator can call it.
 
    11.  Initialize TTLPTR correctly.
 
    12.  Re-work the code so that LINK cannot possibly start
         to page at that point.
 
    13.  Correct the test to not be off by one.
 
    14.  Change the routine that decides how far the runtime
         symbol  table  can  be  allowed to extend.  The new
         algorithm looks for the  first  psect  origin  that
         lies  beyond  where  the  symbol  table starts, and
         ignores zero length psects during its search.
 
    15.  Remove the code to reserve 100 words beyond the end
         of  the  symbol  table.   The symbol table will now
         always be allowed to run right  up  into  (but  not
         overlap) the next psect.
 
    16.  Initialize the /UPTO parameter to  a  large  number
         before writing the overlay symbol tables.
 
    17.  Insert code to delete the nnnLAS.TMP  file  if  the
Digital Equipment Corporation       28-AUG-79    Page 482
PCO Log Report


         user does not want it.
 
    18.  Remove the routines  to  do  memory  management  by
         hand,  and  replace  them by calls to LNKCOR except
         where absolutely necessary to do something by hand.
 
 
     This PCO has been made for informational purposes only.
Due  to  the  size  and  complexity of this edit, no attempt
should be made to install it as a patch to LINK  version  4.
This  edit  requires  edits  770,  772, 773, 774, 776, 1110,
1111, 1113, 1121, 1127, 1132, 1144, 1145, 1146, 1152,  1155,
and 1160 to have been previously installed.

     LINK can forget to allocate pages containing  a  common
block  declared  with  the  /COMMON  switch.  This will only
occur if no modules are loaded after the /COMMON switch, and
only if LINK is writing an EXE file.
 

                        **********


[DIAGNOSIS]
 
     The /COMMON switch updates the  current  value  of  the
.LOW.  relocation counter, but not the highest location ever
loaded.  If no other module is ever seen, then  the  highest
location loaded counter will remain incorrect.
 

                        **********


[CURE]
 
     Update the  highest  location  loaded  (RC.HL)  in  the
/COMMON switch processor.

                        **********


[SYMPTOM]
 
 
 
 
LINK's error message facility has a number of problems:
 
     1.  Specifying /VERBOSITY:SHORT can result  in  a  variety  of
         fatal  memory  errors  following  a  message  that, in its
         medium form, prints a large amount of variable text.
 
     2.  After edit 1144, defining the logical name  LOG:  as  TTY:
         results in an address check.
 
     3.  Various messages added to LINK by the  psect  project  for
         version  4  did  not include long messages (available with
         the /VERBOSITY:LONG switch) to explain them.  This has the
         additional  side  effect  that  the  LINK  manual does not
         explain these messages, since the appendix describing  all
         messages was generated directly from LINK's sources.
 
     4.  The listing of LNKERR, which lists all messages  in  LINK,
         does not agree with the actual messages in LINK.  As noted
         above, this has adversely affected the LINK manual.
 
     5.  LINK's messages,  especially  the  ones  that  cannot  use
         LINK's  internal  message facility, are in general hard to
         find when debugging and when  attempting  to  keep  LNKERR
         up-to-date.
 
     6.  LINK is missing first line messages and long  explanations
         for  the  more  recent  LOOKUP/RENAME/ENTER  error  codes.
         Again, this has impacted the LINK manual.
 
     7.  Several of  LINK's  messages  print  the  module  or  file
         associated  with  a particular error, but not both.  Also,
         many messages that ought to include  this  information  do
         not.
 
     8.  After edit 1144, the blank line in the log file  following
         the  processing  of  a  link  in  an  overlaid  program is
         missing.
 
     9.  The  code  to  handle  common   portions   of   the   long
         LOOKUP/RENAME/ENTER   messages  was  put  under  REPEAT  0
Digital Equipment Corporation       28-AUG-79    Page 553
PCO Log Report


         (turned off)  without  including  the  text  in  the  long
         messages.
 
    10.  Several of LINK's messages do not get written to  the  log
         file as they should, or are not under control of the /LOG,
         /LOGLEVEL,  /ERRORLEVEL  or  /VERBOSITY  switches.    Some
         examples   are  the  LNKUGS,  LNKRER,  LNKRLC  and  LNKLSS
         messages.
 
    11.  Long (multi-line) messages are not very  readable  in  the
         log  file.  Typically, the heading of a list does not line
         up with the data under it.
 
 

                        **********


[DIAGNOSIS]
 
 
     1.  If a JMP code is used in an  .ETC.  macro  representing  a
         non-fatal  error,  LINK is supposed to follow the JMP to a
         message continuation  list  and  subsequent  return  after
         printing  the  message.   However, if the /VERBOSITY:SHORT
         switch is specified, LINK attempts to speed error  message
         processing  by skipping any .ETC. codes.  This causes LINK
         to return to a random word following the message.
 
     2.  Edit 1144 made log file initialization always  use  LINK's
         generalized  file initialization routines.  Unfortunately,
         edit 604 made these routines fail for terminals other than
         the controlling one.
 
     3.  The long messages were inadvertently left out.
 
     4&5.The difficulty of finding LINK's messages in  the  sources
         has generally led to LNKERR getting out of date.
 
     6.  LINK's table must be periodically updated as  new  monitor
         error codes are added.
 
     7.  There is no  general  facility  to  print  common  message
         segments,  so  each  maintainer  or  developer  has had to
         remember to include the module and file in all appropriate
         messages.   This  has  made  it difficult to keep all such
         messages consistent.
 
     8.  The feature that printed a blank  line  in  the  log  file
         relied  on  a bug in LINK that was fixed by edit 1144.  In
         particular, the blank line feature required a  bit  to  be
Digital Equipment Corporation       28-AUG-79    Page 554
PCO Log Report


         saved  by a byte pointer that was not intended to save it.
         Since edit 1144 caused the byte pointer to save only  what
         it was supposed to, the blank line bit got lost.
 
     9.  The  common  message  feature  was  turned   off   without
         realizing its effect on the long LOOKUP/RENAME/ENTER text.
 
    10.  The affected messages do not use LINK's  internal  message
         facility,  but  instead  do  everything  by  hand.   These
         messages neglect to take the  log  file  into  account  if
         necessary.
 
    11.  Many of LINK's more complex messages contain imbedded tabs
         to  line  up  columns of data.  This works on the terminal
         because each new line starts at a tab stop.  However,  the
         combination  of the time-stamp, level and severity numbers
         and error code in the log file does not end on a tab stop.
         Thus, subsequent tabs in the text do not line up.
 
 

                        **********


[CURE]
 
 
     1.  Make LINK's error message routines only ignore those .ETC.
         codes that do not affect program control.
 
     2.  Fix  LINK's  file  initialization  routines  to  correctly
         detect the job's controlling terminal.
 
     3.  Include long message text for all messages.  This  affects
         the following messages:
 
                LNKDEB  LNKDLT  LNKEGD  LNKELF  LNKIMI  LNKIMM
                LNKIRC  LNKIRR  LNKISS  LNKIUU  LNKLFC  LNKLFI
                LNKLNS  LNKLSS  LNKNSA  LNKONS  LNKRER  LNKRLC
                LNKRME  LNKUGS  LNKVAL  LNKXCT
 
     4&5.Label all  of  LINK's  error  messages  with  well-defined
         labels.   Also, use a special OPDEF in place of OUTSTR for
         those  messages  that  cannot  use  the  regular   message
         facility.   This  makes  all messages easy to find both in
         the listing and in  debugging  versions  of  LINK.   Then,
         update LNKERR so that it agrees with the real messages.
 
     6.  Update   LINK's   tables   to    include    all    current
         LOOKUP/RENAME/ENTER  errors.   This  affects the following
         messages:
Digital Equipment Corporation       28-AUG-79    Page 555
PCO Log Report


 
                LNKFEE  LNKFLE  LNKFRE  LNKGSE
 
     7.  Add a facility to print common segments of  messages,  and
         use  it  to  print  the  module  and  file currently being
         processed wherever possible.  This affects  the  following
         messages:
 
                LNKAIC  LNKB4R  LNKCCD  LNKCMC  LNKCMF  LNKDRC
                LNKDSC  LNKDSL  LNKDSO  LNKFCD  LNKFOV  LNKFSF
                LNKHCL  LNKHSL  LNKI4D  LNKI4S  LNKI4T  LNKICB
                LNKIPO  LNKIPX  LNKIRB  LNKIRC  LNKIRR  LNKISD
                LNKISN  LNKISO  LNKMDS  LNKMSR  LNKOFN  LNKPBI
                LNKRBS  LNKSRB  LNKSRP  LNKSTL  LNKT13  LNKTMA
                LNKUAR  LNKURC
 
     8.  Add a new function to .ETC. to print a blank line  in  the
         log file, since the bit used before cannot work.
 
     9.  Include    the    common    portions    of    the     long
         LOOKUP/RENAME/ENTER messages directly in the long text for
         each  separate  message.   This  affects   the   following
         messages:
 
                LNKFEE  LNKFLE  LNKFRE  LNKGSE
 
    10.  Make the following messages use  LINK's  internal  message
         facility  so  that  these  messages get written to the log
         file when necessary:
 
                LNKEGD  LNKLFB  LNKLFC  LNKLFI  LNKLIN  LNKLSS
                LNKRER  LNKRLC  LNKUGS
 
 
    11.  Restructure the log file format slightly so that the  text
         portion of each message begins on a tab stop.
 
As a result of a general clean-up  of  LINK's  messages  also  done
along with this edit, the following message mnemonics were changed:
 
       LNKIBC, LNKTEC --> LNKAIC        LNKEOI, LNKEID --> LNKEIF
       LNKANC --> LNKANM        LNKCEF --> LNKMEF
       LNK999 --> LNKEGD        LNKICI --> LNKIMI
       LNKITT --> LNKICB        LNKIFD --> LNKOFD
       LNKIPL --> LNKIRR        LNKLIM --> LNKLIN
       LNKLNC --> LNKLNM        LNKODV --> LNKOFS
       LNKSLS --> LNKOSL        LNLRPN --> LNKSRP
       LNKRUC --> LNKRUM
 
Also, the following messages were deleted:

                        **********


[SYMPTOM]
 
 
 
 
     LINK will accept /UPTO:symbol, but will ignore it.
 

                        **********


[DIAGNOSIS]
 
     The switch tables say it will take a symbol  name,  but
there is no support code anywhere else to implement it.
 

                        **********


[CURE]
 
     Add the support code, including the new LNKUUA message.
As  part of this edit, /START:symbol was made to not look up
the symbol until LINK  sees  /GO,  in  case  the  symbol  is
defined in a later module.  Also, a bug that caused LINK not
to define the symbol %OWN for Algol programs if LINK  issued
the LNKUSA message has been fixed.
 
     This edit requires edit 1174, and thus  should  NOT  be
installed as a patch.

[SYMPTOM]
 
 
 
 
     If a command string to  LINK  contains  /VERSION  in  a
global  context, then any local switches associated with the
same file spec will be lost.  This  will  only  happen  with
LINK  3A or earlier, or with LINK 4 after edit 1122 has been
installed.
 

                        **********


[DIAGNOSIS]
 
     The /VERSION switch  processing  routine  always  calls
STRLSW,  which  is  not  legal for switches seen in a global
context.
 

                        **********


[CURE]
 
     Add a new entry to the /VERSION processing routine that
does not call STRLSW, and get to it if /VERSION is seen in a
global context.
 
     This edit requires edit 1122.

[SYMPTOM]
 
 
 
 
     In order to support concealed mode,  FOROTS  version  6
needs  LINK  to  search  SYS:FORLIB  in /SEGMENT:LOW mode if
loading in /OTS:SHARABLE mode.
 

                        **********


[DIAGNOSIS]
 
     It's in the design spec.
 

                        **********


[CURE]
 
     Implement it.  Note that this edit requires edit 1201.

                        **********


[SYMPTOM]
 
 
 
 
     LINK  accepts  /SEGMENT:PSECT,  but  blows  up   during
loading.
 

                        **********


[DIAGNOSIS]
 
     The  PSECT  keyword   to   /SEGMENT   was   implemented
accidentally  when /SYMSEG:PSECT was implemented, since both
switches use the same keyword  list.   The  /SEGMENT  switch
processing  routine  is  not  expecting  this,  however, and
destroys the flag word when it sees it.
 

                        **********


[CURE]
 
     Split the switch keywords into two different lists.

                        **********


[SYMPTOM]
 
 
 
 
     If a user loads a program that extends beyond  location
777777,   then  LINK  will  not  issue  any  error  message.
Instead, LINK  will  produce  a  bad  image  with  no  error
message, loop, or fail with an illegal memory reference.
 

                        **********


[DIAGNOSIS]
 
     There are no checks for this anywhere in LINK.   It  is
difficult to check, since addresses are truncated to 18 bits
in the lowest level input routine.
 

                        **********


[CURE]
 
     Make the low-level routine  save  the  full-word  value
that  it  read,  and then use this value check for loading a
program that extends beyond 777777.  If  this  is  detected,
LINK will issue the new LNKPTL message.

                        **********


[SYMPTOM]
 
 
 
 
     The  overlay  files  created  by  LINK  version  4  are
appreciably  larger  than  those created by LINK version 3A.
The extra disk space just contains zero.
 

                        **********


[DIAGNOSIS]
 
     Between LINK 3A and 4, LINK's internal  page 718ze  was
changed   from   200   words  to  1000  words.   However,  a
calculation of required disk space in LNKOV1 referenced  the
symbol  for the internal page size, assuming that it was the
same as the disk block size.  Since this is no longer  true,
the rounding being performed uses unneeded disk blocks.
 

                        **********


[CURE]
 
     Correct the rounding to use the symbol for  disk  block
size.   Note that even with this edit installed, the overlay
file will not be of identical size,  since  some  of  LINK's
internal  tables  that  get  stored in the overlay file have
changed in size since LINK 3A.

                        **********


[SYMPTOM]
 
 
 
 
     After edit 1203 has been installed, LINK will not allow
block type 5s (Program End block) that contain only one data
word.  This type of block is generated by the Algol and SAIL
compilers.   Also,  LINK  thinks  that  a  program  break of
exactly 1,,0 is illegal.
 

                        **********


[DIAGNOSIS]
 
     Before edit 1203, LINK read the block  type  5  with  a
call  to  RB.2.   This routine (1) just assumed zero for the
second data word if it wasn't there, and (2) never  returned
a  program  break  of  1,,0.   Edit 1203 changed this to two
calls to RB.1, both of which went to the LNKRBS error if the
data  word  was not present.  In addition, some new code was
added to let a program break of 1,,0 through, but this break
is then disallowed by an immediately following check for the
LNKPBI message.
 

                        **********


[CURE]
 
     Just assume zero if the  second  call  to  RB.1  fails.

[SYMPTOM]
 
 
 
 
     After edit 1174 has been installed, LINK will fail with
an  illegal UUO immediately after issuing the LNKDRC warning
message.
 

                        **********


[DIAGNOSIS]
 
     An error in that edit causes LINK  to  start  executing
its  error  codes  as if they were instructions.  Since they
aren't, an illegal UUO soon follows.
 

                        **********


[CURE]
 
     Correct that part of edit 1174.

[SYMPTOM]
 
 
 
 
Various loose ends following the error  message  clean-up  of  edit
1174:
 
     1.  The LNKAIC and RLC  messages  are  not  very  readable  in
         LNKERR.MAC.
 
     2.  The  LNKGFE  long  message  should  be  in   IFN   TOPS-20
         conditionals.
 
     3.  References in LNKERR  to  the  message  segment  [address]
         should be [octal], and the associated messages should tell
         the user that these quantities are addresses.
 
     4.  Indexed message 7 refers to a SAV file, even  though  .EXE
         files have been around a long time.
 
     5.  The changing of references of `core'  to  `memory'  missed
         the one in indexed message 10.
 
     6.  LNKERR.MAC incorrectly states that  the  messages  LNKFEE,
         LNKFLE  and  LNKFRE  are  unconditionally  of level 31 and
         severity 31.
 
     7.  Some messages resulting from  the  failure  of  a  LOOKUP,
         ENTER, RENAME, RUN or GETSEG UUO are missing a space.
 
     8.  The TOPS-20 long message for LNKEOV refers  to  the  saved
         file, when the failure was actually for the overlay file.
 
     9.  Some labels inside of unsupported  conditionals  were  not
         changed to the new format.
 
 
This edit should not be installed in the field, since  it  requires
nearly every other LINK edit to be installed first.

                        **********


[SYMPTOM]
 
 
 
 
     LINK will give a LNKISD warning when certain  types  of
programs  are assembled with MACRO 53A.  Programs that cause
this are  those  that  contain  a  partially-defined  global
symbol which is used in more than one psect.
 

                        **********


[DIAGNOSIS]
 
     In this case, MACRO 53A generates a  duplicate  partial
definition   for   each   different   psect   in  which  the
partially-defined symbol was used.  The partial  definitions
will  eventually  turn  out to have the same value, but LINK
doesn't wait to see if they will or not before printing  its
warning.   It  is  not  feasible  to make MACRO 53A act like
MACRO 53 and earlier did, since this behavior was introduced
as a side effect of fixing a serious bug with psects.
 

                        **********


[CURE]
 
     Remove  the  ISD  message  from  LINK.   When  multiple
partial  definitions  are  detected, save them all away.  As
they become defined, compare them against the value  of  the
first definition seen (the "real" definition), and print MDS
messages if the values differ.

                        **********


[SYMPTOM]
 
 
 
 
Quality assurance tests done  on  LINK's  sources  using  PIP's  /V
switch (list unmatched angle brackets) find various unmatched angle
bracket problems.
 

                        **********


[DIAGNOSIS]
 
There are two sets of problems.
 
     1.  Several comments sprinkled throughout the sources  include
         angle  brackets  that are used for relational expressions.
         Every one of these leads to potential  problems  if  these
         lines are someday put inside conditionals.
 
     2.  Edit 1132 missed the matching closing  angle  bracket  for
         the FTOVERLAY conditional in the vicinity of XOVNWD.  This
         only causes problems if FTEXE is turned off (this  is  not
         supported).
 
 

                        **********


[CURE]
 
Fix the various unmatched angle brackets.

                        **********


[SYMPTOM]
 
 
 
 
     LINK can leave  location  140  to  the  first  location
loaded  with  relocatable  code out of the EXE file, even if
these locations were loaded with absolute code.   This  will
only  happen  if  LINK  is  writing its own EXE file, and if
LINK's internal LC area has overflowed to disk.
 

                        **********


[DIAGNOSIS]
 
     LINK's EXE file writer  finds  the  lowest  significant
location  beyond  JOBDAT by looking at the current values of
the .LOW. and .ABS. relocation counters.  Unfortunately, the
current  value  of the .ABS. counter is always zero, so that
the  EXE  file  writer  will  miss  the  first   significant
location(s) if they were loaded with absolute code.
 

                        **********


[CURE]
 
     Use the highest location seen, RC.HL, instead of RC.CV.
This edit is NOT applicable to field image LINK version 4.
