     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.
