# This script is used to calculate two basic properties of the branch prediction
# 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 *.life dumps. You need to pass the -df switch to the compiler as well
+# saved into *.bp dumps. You need to pass the -db 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:
