------- Comment #6 from howarth at nitro dot med dot uc dot edu 2010-03-10 01:57 ------- The code being degraded by -fgraphite-identity (when using -ffast-math -funroll-loops -O3) is in the mqr_m and mqc_m modules. The exact distribution of performance loss in execution time for the induct benchmark is...
no use of -fgraphite-identity 12.695 sec -fgraphite-identity for all 20.177 sec -fgraphite-identity for all but mqc_m 14.293 sec -fgraphite-identity for all but mqr_m 18.598 sec -fgraphite-identity for all but mqc_m and mqr_m 12.677 sec as benchmarked on x86_64-apple-darwin10. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40979
