# Uncomment one of the following BuildFlavour settings to get the desired
# overall build type, and then tweak the options in the relevant section
# below.

# Uncomment one of these to select a build profile below:

# Full build with max optimisation and everything enabled (very slow build)
#BuildFlavour = perf

# As above but build GHC using the LLVM backend
#BuildFlavour = perf-llvm

# Fast build with optimised libraries, no profiling (RECOMMENDED):
#BuildFlavour = quick

# Even faster build.  NOT RECOMMENDED: the libraries will be
# completely unoptimised, so any code built with this compiler
# (including stage2) will run very slowly:
#BuildFlavour = quickest

# Profile the stage2 compiler:
#BuildFlavour = prof

# A development build, working on the stage 1 compiler:
#BuildFlavour = devel1

# A development build, working on the stage 2 compiler:
#BuildFlavour = devel2

# An unregisterised, optimised build of ghc, for porting:
#BuildFlavour = unreg
