Our positron branch has the fix for this in it. We should dig it out and
submit it.

Mike, any news on that? You can still make it in time for the 5th anniversary
of this PR! :)

Still fails on both ppc-darwin and i386-darwin, for 4.3.2, 4.4.0 and current
trunk:
$ cat a.c
extern int puts (const char *);
extern void abort (void);
int main ()
{
__label__ l1;
void foo ()
{
void bar ()
{
puts ("goto l1");
goto l1;
}
bar ();
}
foo ();
abort ();
l1:
puts ("label l1");
return 0;
}
$ gcc -O3 a.c && ./a.out
goto l1
label l1
$ gcc -O0 a.c && ./a.out
goto l1
(It also fails with Apple's gcc.)

No problem that it still fails. It will be fixed after the next big-bang, in
thirty billion years.

I have a fix for this in progress see also PR 51784.
JFTR, I suspect the issue is moot in clang/llvm because they don't support
nested functions AFAICT - but use 'blocks' instead.
BTW, is there any access to the 'positron' branch - was it ever on an FSF
server?

apple-branch is what's on the FSF server. The positron branch should be on the
Apple open source website, though, just grabbing the top of the tree (latest
version of gcc-4.2) I think would be preferable. There is a version in the
llvm repo, though, it does have all the llvm goop in it as well.

Created attachment 26370
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26370
initial fix
this shares some changes with the fix to PR51784 (and that is somewhere to read
about the issues that prevent an easier fix).
AFAICT, the bugs are still present in the Apple OS tree - at least they are
with 4.2.1/5577 - which postdates the comments here.
Anyway, this is a starting point - I expect that there is scope to tidy it up.
As things stand we need to differentiate the load-picbase from the
reload-picbase on PPC because more of the work is done in the md. On x86 it's
hidden away in i386.c - which made it easier to fix there.

I have done a clean bootstrap of r183305 on powerpc-apple-darwin9 with the
patch in comment #25.
Regtesting in progress (allow for ~20 more hours), but gcc at -m32 has only 28
failures (including 16 for gcc.dg/simulate-thread/atomic-* instead of usually
12: I cannot say presently if it is due to some slow down due to the patch or
because I am using the machine while usually it is only devoted to the test
suite).
