--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Richard Biener from comment #3) > mgrid also on AMD Fam10: > https://gcc.opensuse.org/gcc-old/SPEC/CFP/sb-megrez-head-64/recent.html Interesting about this regression is that mgrid is a single source benchmark. Thus I would not expect a difference in between LTO and non-LTO mode.
