--- Comment #42 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-12-07 13:40:17 UTC --- > Re-adjust target milestone. Please somebody revisit the regression status > and fill in known-to-work/fail fields. ISTR it only fails on darwin. (1) doduc.f90 is correctly compiled on x86_64-apple-darwin10 (r194291) with the options I have tried (typically -fprotect-parens -Ofast -funroll-loops -ftree-loop-linear -fomit-frame-pointer -fwhole-program -flto, no valgrind error with -O3 -ffast-math, no error with -fsanitize=address). (2) Per comment #30, this PR has been reopened for x86_64-unknown-linux-gnu. (3) Per comment #40: > tree if-conversion happily executes both arms of the conditional > unconditionally with -ffast-math, ... so compiling with -ffpe-trap=invalid traps for results discarded later.
