I'm guessing you've tried these flags mentioned in the blog post but haven't had luck with them? > LLVM supports an interesting feature called Optimization Remarks – these remarks track whether an optimization was performed or missed. Clang support recording remarks using -fsave-optimization-record and Rustc supports -Zremark-dir=<blah>. There are also some tools (opt-viewer.py, optview2) to help view and understand the output. |
