--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> 2010-10-15 01:29:38 UTC --- Updated summary... - Last patch needed to get Mozilla working is posted as http://gcc.gnu.org/ml/gcc-patches/2010-10/msg01286.html - Configuration needs to be done with -fwhopr for C++ and -flto for C, to get around sqlite problem (PR44897) - Debugging still needs to be disabled - Recent Gold is needed - Peak memory use is about 4GB, still more than we should need. It is WPA stage having too many declarations in it. - We probably could do better on devirtualization in constructors for addref. With -O3 --param inline-unit-growth -fwhopr=jobserv the code size seems comparable with non-LTO -Os build, speed with non-LTO -O3 build. This seems quite good news. Lacking debug info build seems to be the only remaining showstopper for practical use.
