gcc 4.3.3 anyone?

Hi,

I've ran into what appears to be a bug in gcc 4.3.2 and reported it
here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39076

Now I consider to try to update buildroot to use gcc 4.3.3. But as there are a number of patches for each gcc version this could become quite some work. That's why I'm asking if anyone has already done that and wants to share his/her experience/patches?

I was going to bump the gcc version right after the release, but if someone else want to do it, that's fine as well.

I wouldn't do it for the release though.

Hi,

The gcc people have fixed this problem in the gcc-4.3 branch. I verified that the patch fixes the compiler segfault when compiling flac. Attached is a patch for buildroot that incorporates this fix for gcc 4.3.2.

I also noticed that two of the patches in toolchain/gcc/4.3.2 don't end in .patch and thus are not applied. Is this intentional?

Thanks, will apply.

No, not afaik. The 995-short-enums.diff comes from Bernhard and is a fix for PR34205 which got tagged WONTFIX upstream
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34205), and afaik shouldn't be needed now we don't use abi=iwmmxt anymore - Bernhard, correct me if I'm wrong - Otherwise I'll remove it.

The 306-arm-funroll-loops.patch.arm is from Ulf (r24993), and not just the name is wrong, it doesn't apply (wrong patch level). I've fixed that up and am now doing a test build to check if it fixes the mplayer ICE. If so, then I'll commit, otherwise I'll remove it.

Thanks for noticing!

I checked, and your patch seems to be the same a 2nd hunk of Ulf's 306-arm-funroll-loops.patch, so it isn't needed anymore.
