[PATCH] D89158: [NewPM] Run all EP callbacks under -O0

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

If you are not invoking all the needed callbacks in invokeRegisteredO0EPCallbacks(), I would suggest to instead provide a set of methods like invokePipelineStartEPCallbacks(), invokeOptimizerLastEPCallbacks() that allow the consumer to chose which callbacks to invoke. (Just those two would be sufficient for my purposes.)

I'd really like to avoid this dance: https://github.com/rust-lang/rust/blob/c71248b70870960af9993de4f31d3cba9bbce7e8/compiler/rustc_llvm/llvm-wrapper/PassWrapper.cpp#L796 Where you need to separately collect all callbacks yourself, because the PassBuilder neither makes the necessary members public, nor provides a means to invoke the callbacks explicitly.
