Hi, The patch (http://gcc.gnu.org/bugzilla/attachment.cgi?id=26585) attached to the bug (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52137) recovers performance regressions for AMD's bdver2 processor.
It passes bootstrap and make check on x86_64. The patch is simple and seems to have little risk, therefore AMD would like to see if this patch can be included in 4.7.0. Okay to commit to trunk? -- Quentin
