--- Comment #17 from sje at cup dot hp dot com 2010-04-16 22:29 --- Is there any reason none of the patches created for this bug have been checked in?

--- Comment #14 from janis at gcc dot gnu dot org 2007-08-28 18:15 --- The patch that I tried is the one attached for comment #10, not the one in comment #9. With that patch a bootstrap of all languages but Ada succeeded. The test results look reasonable, although I don't have results from the last few days with which to compare them. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31490

--- Comment #12 from janis at gcc dot gnu dot org 2007-08-27 21:54 --- Trunk currently fails on powerpc64-linux building libstdc++-v3/src/system_error.cc. Hacking libtool a bit allows seeing the message std::system_category causes a section type conflict. The file is compiled with -O2 and -fdata-sections; if either of those is removed then the bootstrap succeeds. This PR looked related (and Andrew Pinski confirmed that it is) so I tried the patch from comment #10; it needs more parens to avoid warnings, but with that patch the bootstrap succeeds. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31490

--- Comment #8 from segher at kernel dot crashing dot org 2007-05-15 13:07 --- Bisecting shows that the original bug (powerpc64 Linux build errors out) is caused by r122781. I didn't actually test on 4.2 but the same patch is applied there (as r122782). If the reduced testcase in comment #2 fails on older compilers, it is likely a different bug (or an invalid testcase); if a bug, please file a separate PR for it. -- segher at kernel dot crashing dot org changed: What|Removed |Added CC||segher at kernel dot ||crashing dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31490
