#
# Some GHC flags explained
#
# -v verbose mode
# -O2 level 2 optimizations
# -rtsopts allow +RTS flags
# -prof enable basic time and allocation profiling
# -auto-all cost centers on all top level functions
# (you can also add them via the SCC pragma)
# -caf-all generate data for CAFs (constant applicative forms)
# t
# -fforce-recomp force recompilation
#
# Notes: you will obtain the profiling versions of dependancies via:
# stack install --profile [libraryname]
#
# -fprof-auto replaced -auto-all
# -fprof-cafs replaced -caf-all
#
build-prof:
stack ghc --profile -- -rtsopts -prof -fprof-auto -fprof-cafs -O2 base64.hs
#
# Some +RTS flags
#
# -p profiling
# -K set stack limit
# -hc extract heap profile
# -hy allocation by type
# -hd allocation by constructor
# -iN sampling frequency in seconds. e.g. -i0.01
# -ddump-simpl generate core version
#
# Note: render the heap profile as graph with: hp2ps -e8in -c file.hp
#
run-prof:
cat random.bin | ./base64 +RTS -p -K100M > /dev/null
test-mini-hask:
#stack ghc -- -rtsopts -prof -fprof-auto -fprof-cafs -O mini.hs -o mini_hask_exe
stack ghc -- -O mini.hs -o mini_hask_exe
test-mini-c:
gcc -O3 mini.c -o mini_c_exe
