Thanks! It is interesting that I do not see similar observations on Czerny which also runs spec2006. In partiuclar both AMD machines agrees on soplex milc and bwaves. They are flat in Czerny graph, so it may be again dependency of AMD machines on code lyaout we was seeing recently. https://gcc.opensuse.org/gcc-old/SPEC/CFP/sb-czerny-head-64-2006/410_bwaves_recent_big.png https://gcc.opensuse.org/gcc-old/SPEC/CFP/sb-czerny-head-64-2006/433_milc_recent_big.png https://gcc.opensuse.org/gcc-old/SPEC/CFP/sb-czerny-head-64-2006/450_soplex_recent_big.png We sould take a look at spoplex. Megrez will pick up the patch tonight so we will see if the regression reproduces on both bulldozer machines.
