# Step 1: Compile and profile your program. You need to use -fprofile-arcs
# flag to get the profiles
# Step 2: Generate log files. The information about given heuristics are
# saved into *.bp dumps. You need to pass the -db switch to the compiler as well
# saved into ipa-profile dumps. You need to pass the -fdimp-ipa-profile switch
# to the compiler as well
# as -fbranch-probabilities to get the results of profiling noted in the dumps.
# Ensure that there are no "Arc profiling: some edge counts were bad." warnings.
# Step 3: Run this script to concatenate all *.life files:
# analyze_brprob `find . -name *.life`
# Step 3: Run this script to concatenate all *.profile files:
# analyze_brprob `find . -name *.profile`
# the information is collected and print once all files are parsed. This
# may take a while.
# Note that the script does use bc to perform long arithmetic.
