--- Comment #17 from Eric Botcazou <ebotcazou at gcc dot gnu.org> 2011-11-19 07:17:58 UTC --- > I tested on machine with -march=amdfam10, with your patch induct run time > improves by ~5%. Other benchmarks are not affected much. OK, thanks. > With your patch, CPU2006 benchmark "416.gamess" fails during validation. > Mimimal flag -O3 -fno-tree-pre -mfma4. I am trying to reduce the test case. > Please let me know if you have any other suggestions. I think that this should be handled at the Tree level. The missed optimization opportunities are there, with or without -fprotect-parens.
