Category: Driver Group: 5.04.1 >Status: Open Resolution: None Priority: 5 Submitted By: Joe English (jenglish) Assigned to: Nobody/Anonymous (nobody) Summary: Still fails to build with GCC 3.2 on Mandrake Initial Comment: Following the instructions listed in other bug reports, I bootstrapped GHC 5.04.1 on a machine with an older GCC, then installed that on the target machine (Mandrake 9.0, GCC 3.2). But the mangler is still busted: compiling anything with -O gives errors like: | Prologue junk?: .globl __stginit_PrimPacked | .type __stginit_PrimPacked,@function | __stginit_PrimPacked: | pushl %ebp | movl %esp, %ebp Compiling with '-O -fasm' works, but GHC 5.04.1 still can't recompile itself since parts of it require '-O -fvia-C'. I also tried downloading the current version of ghc-asm.lprl from the CVS repository and using that; still get the same errors. ---------------------------------------------------------------------- >Comment By: Simon Marlow (simonmar) Date: 2002-12-03 11:35 Message: Logged In: YES user_id=48280 Re-opened; we really need a workaround for this one. ---------------------------------------------------------------------- Comment By: Joe English (jenglish) Date: 2002-11-28 00:00 Message: Logged In: YES user_id=68433 Yep, adding -mno-omit-leaf-frame-pointer did the trick. Problem solved! ---------------------------------------------------------------------- Comment By: Joe English (jenglish) Date: 2002-11-26 21:18 Message: Logged In: YES user_id=68433 I think I've found the problem: the mangler relies on -fomit-frame-pointer, but gcc-3.2mdk turns -momit-leaf-frame-pointer on by default. The latter flag (apparently) overrides the former, so non-leaf functions end up with unexpected junk in the prologue. I'll try -mno-omit-leaf-frame-pointer and see if that works. (I don't have access to my Mandrake box at the moment; but I can get ghc to *break* in the same way on a Red Hat 8.0 system with `ghc -c -O -optc -momit-leaf-frame-pointer`, so that's a promising sign :-) ---------------------------------------------------------------------- Comment By: Joe English (jenglish) Date: 2002-11-26 18:24 Message: Logged In: YES user_id=68433 Nope, that's not it either. Using ghc -O -v -pgmc "gcc-3.2 -march=i386 -mcpu=i386" gives the same result. Back to the drawing board... ---------------------------------------------------------------------- Comment By: Joe English (jenglish) Date: 2002-11-26 16:00 Message: Logged In: YES user_id=68433 Aha: Mandrake's GCC is configured to compile for i586, while Redhat's is configured for i386. I'll bet this is the source of the problem. Will investigate further... ---------------------------------------------------------------------- Comment By: Simon Marlow (simonmar) Date: 2002-11-26 10:48 Message: Logged In: YES user_id=48280 Mandrake shipped a broken GCC, it seems. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=108032&aid=642810&group_id=8032 _______________________________________________ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
