--- Comment #11 from Jan Hubicka <hubicka at gcc dot gnu.org> --- The following are passes affecting mismatches for tramp3d -O3 build: 107t cunrolli | 85 +77 110t forwprop | 87 +2 113t fre | 151 +64 115t threadfull | 474 +323 116t vrp | 379 -95 127t ch | 3106 +2729 130t thread | 3166 +60 131t dom | 3036 -130 159t cddce | 3146 +109 195t fre | 1232 +10 196t thread | 1259 +27 197t dom | 1249 -10 199t threadfull | 1275 +26 200t vrp | 1264 -11 211t cddce | 1264 +14 264r cprop | 1174 +13 275r loop2_unroll | 1180 +8 312r pro_and_epilogue | 1204 +21 315r jump2 | 1245 +41 So jump threading still produces mismatches, but I will need to look more if these are really conflicting profiles or another updating bug.
