If the patch suggesting this ("[RFA (GCC)] Patch to remove default ELF
definition of ASM_FILE_END" [1]) had engendered any discussion, I was
going to mention that the "GCC: (GNU) ..." stuff can in fact be very
useful when debugging problems involving binary-only libraries from
vendors.  See for example

http://maillist.perforce.com/pipermail/perforce-user/2001-April/005616.html

Good point.  But it can be done without nearly so much gunk in target
headers.  I'll put it back, I have to rev the patch anyway for GDB's
sake.

Right.  I've got a modified patch which unconditionally emits this
stab from dbxout.c.  I'm going to run it through the gdb test suite,
then post it.

I looked at the stabs reader in gdb, and it appears not to care
whether or not the gcc2_compiled stab is after the N_SO; it just
toggles a global variable upon reading an N_OPT stab with string equal
to GCC2_COMPILED_FLAG_SYMBOL.  It does seem semantically better to put
it after the N_SO.  Daniel, do you have an opinion here?

Why don't we just emit this directly in dbxout.c, rather
than conditionalizing it in odd macros?

Right, but he eliminated the STAB as well.
If he just doesn't eliminate the STAB, all should be well.

It's used in weird ways, like determining whether to use structure
returns in hand function calling on some systems, etc.

This one little flag starts pervading all kinds of places.

Personally, I wouldn't care if we break STABS accidently.
I'm in the middle of adding all kinds of dwarf2 stuff to GDB from the
GDB rewrite in C++ I had done (location expression evaluation at
runtime, rather than trying to turn them into other types of gdb
locations, using the call frame info to the frame stuff, etc), as well
as support for the -feliminate-dwarf2-dups.
STABS is the bane of my C++ maintainership in GDB.

But i'm sure someone would be annoyed, so i just wanted to make sure
the gcc2_compiled STAB stays, or someone alerts the GDB mailing list
that it's going away, and whatever breaks as a result needs to be
fixed.

In other words, just inter-group communication.

Re: killing ASM_IDENTIFY_GCC [branch]

[Jim Wilson]

Your patch is wrong.

In config/dbxelf.h you delete the ASM_IDENTIFY_GCC_AFTER_SOURCE macro.
This is required for proper operation of gdb.

Note the distinction between a gcc2_compiled label, emitted by
ASM_IDENTIFY_GCC, which is bad, and the gcc2_compiled stab, emitted by
ASM_IDENTIFY_GCC_AFTER_SOURCE which is good.

The proper place to put extra info for gdb is in the debug info not the symbol
table.  Thus the stab is good, but the label is bad.

I see that various other config files are defining ASM_IDENTIFY_GCC to emit
a stab instead of a label, these need to be kept also.  It is rather curious
that some files claim the gcc2_compiled stab has to be before the N_SO, and
others claim that it has to be after the N_SO.  I believe the Solaris choice is
the right one, which means after the N_SO.  Probably when the Solaris port was
fixed, the same fix was not propagated to other ports that also needed it.
Changing dbxout.c to unconditionally emit the gcc2_compiled stab after the N_SO
is probably OK.  It seems pretty unlikely that an extra stab would confuse
other debuggers.

Is this from eyeballing the code, or is this from running the gdb testsuite?
As far as I know (from many discussions with Stu Grossman), the gcc2_compiled
label is not used at all anymore.  Gdb did try to use it long ago, but it
turned out to be far too hard to use, because the info was in the wrong place.

What does get used is a gcc2_compiled stab that gcc emits.  In fact, on a
Sun Solaris system, we don't emit the gcc2_compiled label by default, so
eliminating it is extremely unlikely to break anything.  See ASM_IDENTIFY_GCC
and ASM_IDENTIFY_GCC_AFTER_SOURCE in gcc/config/dbxelf.h.

So the way that this is supposed to work is gcc emits the gcc2_compiled stab
for gdb, and the gcc2_compiled label is completely useless.  Thus eliminating
the gcc2_compiled label should not break gdb.

One flaw with the current system though is that we only emit the gcc2_compiled
stab on systems that include dbxelf.h, and not all ELF systems do.  Certainly
no COFF systems do, but those are less interesting nowadays.  If this shows
up as gdb testsuite problems, then it shouldn't be hard to fix by adding
the gcc2_compiled stab to targets that need it.

Hmmm.

Could we get away with changing the gcc2_compiled.: symbol to a N_OPT
stab on all platforms?  I see logic to accept this in dbxread.c and I
think it wouldn't cause nearly so many problems.

A little more investigation shows I missed the small part of the
source that sets the value of a global variable that *is* used
(because it's really in dbxread.c, not stabsread.c, where one would
expect it).

grep stabsread.c and dbxread.c for processing_gcc_compilation.  There are a few
small, but somewhat important differences, in where the info is
getting placed, and how it gets processed.

This patch will break STABS in gdb.

For one thing, it appears that line numbers for symbols will stop
working completely (don't even ask, actually noticing this made me
want to throw up).  Local symbols look like they'll be borked in some
says, as do a few other things.

There is a lot of annoying stuff in processing STABS in gdb.  I could work
around most of it by saying "if we aren't on a sun, and we have STABS
debug info, we are processing gcc compiled stuff" (since it's sun's dbx stuff that
all these problems/workarounds are implemented for). However, I can't
do this unless the sun ones are moved to DWARF2 as the default with
this change as well (so that stabs no longer occurs, and stabs that
does occur will have the symbol, or be sun compiled stuff).
Unless Sun's compiler also outputs gcc2_compiled these days, i don't know.

killing ASM_IDENTIFY_GCC [branch]

[Zack Weinberg]

A couple weeks back it was pretty much agreed that ASM_IDENTIFY_GCC
should go away, but no one bothered to actually do it.  So I did.
I also knocked out the .ident "GCC: (GNU) ..." stuff which is equally
useless (albeit harmless) and .version "01.01" in most places.
Commentary in elfos.h indicates that some assemblers insist on the
.version directive, so I left it in where I wasn't sure GAS was in
use; also in c4x.h where it is actually used constructively.

The patch deletes an amazing amount of cruft; it seems A_I_GCC and
A_I_LANGUAGE have been problematic since forever.

We get a small object-file size reduction - these were compiled with
-pg so that ASM_IDENTIFY_GCC would cause the maximum amount of
trouble:

before:
        .file   "tmp-dum.c"
        .version        "01.01"
gcc2_compiled.:
        nop
        .comm   xxy_us_dummy,4,4
        .ident  "GCC: (GNU) 3.0 20010410 (prerelease)"

223 bytes saved per object file is not trivial in an embedded
environment, especially when strip doesn't know to remove .comment and
.note sections.  I've got an unstripped libc.so.6 here, and it has 60K
of "GCC: (GNU) 2.95.3 20010315 (Debian release)" and "01.01" strings.

This is against the branch; if approved I'll apply to mainline too.
Bootstrapped i386-linux with, I think, no regressions.
