Thanks, Andrey. I think there are 2 "issues" here: 1. register-renaming. (more related to this PR, I think) 2. schuedule-insns. Both of them slows compilation. With ARG4, on SPU, I see: -O1: 9m28.355s -O1 -fno-rename-registers: 0m19.196s -O2: 184m37.492s (not >1000 as I wrote, but >100) -O2 -fno-rename-registers: 31m29.482s -O2 -fno-schedule-insns: 10m26.851s -O2 -fno-rename-registers -fno-schedule-insns: 0m39.425s Should I open a different PR for scheduling? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31850
