     185== The fastest GHC build ==
     186
     187The settings that give you the fastest complete GHC build are these:
     188
     189{{{
     190  SRC_HC_OPTS     = -H64m -Onot -fasm
     191  GhcStage1HcOpts = -O -fasm
     192  GhcStage2HcOpts = -Onot -fasm
     193  GhcLibHcOpts    = -Onot -fasm
     194  GhcLibWays      =
     195  SplitObjs       = NO
     196}}}
     197
     198However, note that the libraries are built without optimisation, so this build isn't very useful.  The stage 2 compiler will be very slow.
