Comment(by rassilon):

 Hrm, I built with a perf flavor build set with:

 {{{

 SRC_HC_OPTS     = -O -H64m
 GhcStage1HcOpts = -O -fasm
 GhcStage2HcOpts = -O2 -fasm -Rghc-timing
 GhcHcOpts       = -Rghc-timing
 GhcLibHcOpts    = -O2 -Rghc-timing
 GhcLibWays     += p

 }}}


 I'll try again with Stage1HcOpts/SRC_HC_OPTS with -O2 and see what
 happens.
