There are experimental patches on my gpc Web page. The last time I checked patched gpc worked quite well on i386 Linux (all tests passed) and on AMD64 (two tests failed). Matthias Klose tried some other Linux platforms -- on MIPS build failed the other have similar results as 3.3.

Thanks for the patches. With some offsets, the diffs apply all.

When building gpc-20030830 with gcc-3.4, I get the following error:

Try the following patch (if you want just remake you have to remove libgpc.a):

Thanks, the compiler now builds, but -O3 seems to be broken.

I also applied the "update16.diff" patches. Was that OK ?

Anyway, I would like to see assembler output (what gpc -S -O3 produces) -- the output from cross-compiler at first glance looks OK.

Hello.s is included.

AFAIKS Darwin backend is doing something very strange when inlining Pascal initialization routines (tries to call them like external ones).

Do you think we should report this to the gcc list ?

If problem is limited to initialization (as a little experiment suggest), then the following patch is w good workaround. It forbids inlining initialization routines -- such inlining is useless anyway.

Thanks for the patch. It does solve the problem.

By the way, after building and installing I have to run ranlib on libgpc.a.

I am now running the testsuite to see if there are any more problems.

I am now running the testsuite to see if there are any more problems.

No problems with the testsuite, except known ones: nlgpp2.pas and fproc.pas (nonlocal goto's) and systemtest.pas (malloc bug in Darwin).

...

<snip> TEST fproc.pas: /var/tmp//ccdFaUpQ.s:unknown:Can't emit reloc {- symbol "LSJR11"} @ file address 800. /var/tmp//ccdFaUpQ.s:unknown:Can't emit reloc {- symbol "LSJR11"} @ file address 796. /var/tmp//ccdFaUpQ.s:unknown:Undefined local symbol L3$pb failed <snip> TEST nlgpp2.pas: /var/tmp//cc4oD0DK.s:unknown:Can't emit reloc {- symbol "LSJR11"} @ file address 1056. /var/tmp//cc4oD0DK.s:unknown:Can't emit reloc {- symbol "LSJR11"} @ file address 1052. /var/tmp//cc4oD0DK.s:unknown:Undefined local symbol L3$pb failed

Same problem on powerpc-apple-darwin with Ada, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10129. To be solved (...) in gcc-3.4, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13093.

Running the testsuite with EXTRA_PFLAGS=--longjmp-all-nonlocal-labels works around the nonlocal goto failures, but used to cause an "Undefined local symbol L3$pb". This has now been fixed in gcc-3.4.
