--- Comment #23 from Jan Hubicka <hubicka at gcc dot gnu.org> 2011-01-07 18:11:39 UTC --- I've updated mozilla tree and rebuilt with top of tree GCC. The resulting binary seems to work well. Two GCC patches are required: http://gcc.gnu.org/ml/gcc-patches/2011-01/msg00210.html solving -fPIC issues (at gold this is silently ignored but we end up with non-PIC shared libraries that is bad for startup time) http://gcc.gnu.org/ml/gcc-patches/2011-01/msg00375.html to solve problem with undefined aliases while building libxul. Mozilla patchset seems same as posted earlier. Will try to move to debug build and try also profile feedback. memory peaks at 6.5GB, so we will not be able to build in 32bit environment unless we solve the issues with storing too many types.
