# 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
# Fast build with optimised libraries, no profiling, with LLVM:
#BuildFlavour = quick-llvm
# 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
