--- Comment #15 from hubicka at ucw dot cz 2010-01-16 12:30 --- Subject: Re: [4.5 regression] ICE in function_and_variable_visibility breaks Ada bootstrap No doubt about that. The problem is, this was installed without mention in the ChangeLog so looks quite unintentional. If this is intentional, you should fix the ChangeLog. Will do, the earlier version of sanity check was wrong. Actually looking into DECL_COMMON implementation, it seems that even for static variables this seems to work as intended at least on i386, so perhaps the sanity check is overactive. I am double checking that now. I will have time to try to reproduce the problem only tomorrow or during weekend (it will be bit tricky as I know of no machine known to fail here I can access easily), Please read comment #5. I am not questioning that. I have somewhat hectic time now and did not notice situation earlier. I am finishing some papers and my thesis now. My apologize for missing this. Will finish patch today.

--- Comment #3 from david dot kirkby at onetel dot net 2010-01-16 14:29 --- (In reply to comment #2) Confirmed. However, this has really low priority: the C++ standard is not a superset of the C99 standard, so a number of things new to C99 are not part of C++, and this is one of them. If you want to write portable code, you should use the std::complex class. If you have cases where you can show that std::complex is slower than using the C99 means, we'd be happy to accept bug reports. Thanks Wolfgang Note this bug, which you considered as low priority since it applied to using C code with the C++ compiler, is not limited to the C++ compiler. Take a look at #42753 where you will see this bug stops one building C code if using gcc. -- david dot kirkby at onetel dot net changed: What|Removed |Added CC||david dot kirkby at onetel ||dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21057

However same ICE is possible to trigger via static int a __attribute__ ((common)) and looking at varasm.c threre are multitude of reasons why COMMON flag is disqualified later. The checks are spred across the varasm.c and some of them are arguably late since things should be finalized after make_decl_rtl. So following patch moves the logic into visibility pass so it will now clear the flag instead of ICEing. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42068

[Bug driver/42690] Undefined reference errors with -flto -fuse-linker-plugin
--- Comment #13 from d dot g dot gorbachev at gmail dot com 2010-01-16 16:55 --- (In reply to comment #12) What options other than -nostdlib prevent gcc from linking libgcc and libc in the produced binary? I know of -nodefaultlibs. To implement this we should always pass -plugin-opt=-pass-through= %(lto_libgcc) and -plugin-opt=-pass-through=-lc to the linker unless something like -nostdlib is used. Wouldn't it be better to add %{fuse-linker-plugin: -plugin-opt=-pass-through=...} to LIBGCC_SPEC and to LIB_SPEC? However, the driver does not really know, whether we link with libgcc and/or libc. Someone can use -nodefaultlibs together with -lc -lgcc and the linker will still fail. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42690

Maybe your FORMAT_CACHE_STRING_LIMIT is not the same thing as the user space format length, so I can not judge your patch. It seems however, that the bug is not stack size dependent. And my box has more than enough memory. So I'm not completely convinced that the issue is a stack or heap size limitation. I further noticed, that the reached last iteration of the inner loop depends on the loop stop value.

A bug in Solaris's headers and a missing feature in GCC that it doesn't work around that bug. Marc Glisse said on gcc-help It looks like it was fixed in trunk in Septembre (r151331), did you check? I downloaded gcc-4.4-20100112, but that did not fix the issue. I was hoping it might be fixed in a 4.4.x series, but no such luck. I just downloaded gcc-4.5-20100114 in the vague hope that it might be fixed, and the snapshot not cause more problems than it solves. I've not compiled that yet - just had to install MPC first. If this is fixed in trunk do you do you know I might get that fix? If possible, I'd like to get just the fix applied to the latest stable release (i.e. 4.4.2 plus the fix), so it is as risk-free as reasonably practical.

[Bug driver/42690] Undefined reference errors with -flto -fuse-linker-plugin
--- Comment #14 from espindola at gcc dot gnu dot org 2010-01-17 05:47 --- I don't think that in general we can support things like -nodefaultlibs -lc -lgcc. Doing that with static libraries and lto is such an uncommon case that it is probably OK to ask the user to also pass -Wl,-pass-through... I am not familiar with the driver code, but if we already have SPEC stings that are used only when linking libgcc or libc, that is the perfect place to add %{fuse-linker-plugin: -plugin-opt=-pass-through=...} -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42690
