Subject: make GhcProfiled work, and add a "prof" flavour to build.mk
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=76c520c095eb2b9d75fb66050b91097c787f5279

make GhcProfiled work, and add a "prof" flavour to build.mk

Building a profiled GHC is as simple as adding

GhcLibWays += p
GhcProfiled = YES

to your build.mk and saying 'make'.  Then you have a profiled
inplace/bin/ghc-stage2.
