Hi, I'm trying the pass of llc --enable-ipra with benchmarks SPEC CPU 2017. I compile this benchmarks with clang -O3, and after, y run llc -O3 -enable-ipra. However, this pass seems not work. If I count the number of mov operations using -enable-ipra or not, I don't get a significant difference. Why doesn't this pass work? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20200610/87db870b/attachment.html>
