Hi, I am trying the pass "loop-predication" of opt in the SPEC CPU 2017 benchmarks. I generate a original version with "clang -O3" and "opt -O3". Later, I generate a loop-predication version with "clang -O3" and "opt -O3 -loop-predication". If I compare the two versions I expected that the branch instructions are reduced with loop-predication. However, they are the same that in the original version. Why do this happen? Thanks! -------------- next part -------------- An HTML attachment was scrubbed...
