Dominique d'Humieres <dominiq at lps dot ens.fr> changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|fatigue2 -flto run time |[4.8 Regression] fatigue2 |regression |-flto run time regression --- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-08-29 15:46:58 UTC --- I see something similar on x86_64-apple-darwin10, but with -fwhole-program and not with -flto: i.e., with -Ofast before or after r190346 the run time is ~150s and does not change with -flto. At r190345 and before, the run time with -fwhole-program is ~100s (and ~56s with --param max-inline-insns-auto=98 -funroll-loops), while it is ~142s at r190346 and after.
