Subject: help with fortran linkage
Message-Id: <"CSI 5679-2881"@CompuServe.COM>
Ken,
I better ask your help on this. My fortran linkage apparently doesn't
work with your new register allocation scheme, and rather than try to figure
out why, I hope you can tell me how I should have done it in the first place.
This SED script applies to your new file, CCGEN2.C; it shows how I generate
a function call to a fortran function. The short description is, first
I push a dummy word onto the stack, then push the arguments in reverse
order, then backpatch the argument into the dummy word, and finally point
Register 16 at the arg count word before doing the PUSHJ. The awkward part
is specifying that I want Register 16 in particular...
Michael
Cut here for SED script CCGEN2.SED:

Message-Id: <"CSI 5679-10860"@CompuServe.COM>
Hi Ken,
Since I haven't heard from you on the utility of the SED scripts I've
been sending you to convey the diffs between your KCC revisions and mine,
I'll go ahead and send you the rest of them on the assumption that you
can use them. There will follow 9 messages containing SED scripts, one
per module. You will also need the 4 I've sent previously to produce a
complete merge of our two revision paths.
If by any chance you haven't received the last few messages, it could
be because I'm still sending them to klh@sri-nic.arpa; I notice your more
recent messages have come from klh@nic.ddn.mil, so I'll try that address
for these messages.
Michael

No, as far as urgency, I was only anxious to know if the scripts I was
sending were usable. I suppose the next order of priority, by my lights,
would be how to fix the fortran linkage; but it's not urgent, I just won't
be able to make the new compiler public yet. Since I haven't heard any
complaints from outside the dept. about the bugs Benny's finding, I have
to assume that fortran linkage is more important to the rest of the co.
Thanks,
Michael

Subject: making smaller links
Message-Id: <"CSI 5680-11841"@CompuServe.COM>
Ken,
Various people have been bugging me to try and cut down
on the memory requirements of KCC, both of the generated code
and of the compiler itself. I've been looking at the runtime
environment, to try and figure out why it pulls in a substantial
part of LIBC even if the user doesn't call anything. It's
obvious that somebody went to a lot of trouble to ensure that,
for instance, the USYS functions don't make calls to the STDIO
functions, but here and there a call must've slipped thru.
What I'd like to do is set up URT.C so I can compile it
conditionally to produce one of several runtime modules:
the first might be just what we have now. The next would be
free of any references that load in the STDIO stuff. Then
there'd be one that was free of any USYS I/O stuff (that'd be
a big win for us, getting rid of that 6K chunk of buffer in
the low seg unles it was needed). Then finally I might have
one that did virtually nothing except call main.
To do this, besides tracking down whatever calls to printf
etc. are made in error messages and the like, I'd have to make
a few non-trivial changes to URT. For one thing, I'd like to
move the call of "atexit(cleanup)" from urt.c to fopen.c,
and have fopen do it the first time it's called (setting a flag).
Otherwise, urt will pull in cleanup into every link, which will
pull in fclose, which pulls in fopen, malloc, printf and the
whole bunch. Does that change seem ethical to you?
To do the same thing with the USYS I/O functions (but leave
them available on demand), I might have to give up the ability
to redirect stdin and stdout, and expand indirect files. The
idea would be to have _openuf() do something similar the first
time it's called, setting up for it's own termination cleanup.
Otherwise _exit() will pull in close(), which will pull in
the rest of the USYS functions.
I'd appreciate your thoughts on the subject.
Michael

RE: a shared library high segment like FORTRAN uses. Did you
look into this and reject it for some reason?
No, I didn't look into it because I don't know much about FORTRAN.
Maybe I should look into this. I think, though, that even if this
helps, it won't satisfy some folks. The idea of conserving system
resources (cycles, words) is pretty firmly entrenched here. After
all, that's what they sell. Can't sell it if we're using it up
ourselves. Don't want to have to purchase additional HW, either!!!
I can sort of see their point of view, though. I mean, why bother to
try to reduce the size of the generated code at all, if we're gonna
pull in ~75K of library code no matter what we do?
Vis: the suggestions in my last message: I've been able to make some
of them work, in a tentative fashion. I can make a runtime without
the STDIO functions at the cost of being able to append to stdout
(the calls to fstat, setbuf and setvbuf in init_uio() have to go).
Then I can make a runtime without the UIO functions or buffers at
the cost of not calling init_uio() at all, meaning I haven't got
stdin, stdout, stderr initialized but I can still pull in the UIO
functions if I need them.

RE: Or would you rather wait until I've integrated your changes?
Well, on the one hand, the "merged" compiler, incorporating both
your changes and ours, is in a sort of limbo since it needs its
fortran linkage fixed. On the other hand, if you don't incorporate
the changes first, we'll have them to do over again. Since the scripts
I sent apply to the files you most recently sent (and they have line
numbers and such in them), wouldn't it be easier for you to apply the
scripts before making any more changes? We'll still have the fix for
fortran to do, but hopefully that'll be small and confined.
RE: modem.
I don't know what Benny sent you, but if it accepts the Hayes (tm)
command set, you can do what you want to in "soft switches" (ie registers):
just send it the string "ATS0=0"<return> from your telecom program. That
tells it to answer the phone only after an infinite number of rings.
Of course, it has to be redone every time you turn the sucker on...
