Hi, I am trying to profile the frequency of each basic block of SPEC 2000 benchmarks by compiling them using -fprofile-arcs and opt -O3. After running the benchmark, when I try to read "bb->count" while compiling using "-fbranch-probabilities and -O3", I get "0" values for basic blocks which were known to execute for sure. Any clue as to where I am missing? Is "bb->count" is the right way to get the dynamic frequency in the second pass?
regards, Raj
