In practice I’ve had limited success with that flag. It still seems to enable optimizations that make debugging difficult.

- senkora 2y agoAgreed. I like to compile most translation units with -O3 and then only compile the translation units that I want to debug with -O0. That way I can often end up with a binary that's reasonably fast but still debuggable for the parts that I care about.
- vlovich123 2y agoYup that’s what I’ve resorted to (in Rust I do it at the crate level instead of translation unit). The only downside is forgetting about it and then wondering why stepping through is failing to work properly.
