[llvm-dev] AddDiscriminatorsPass not in O0 pipeline under NPM

[via llvm-dev]

Hi,

It seems that, under NPM, AddDiscriminatorsPass is not added into the O0 pipeline (buildO0DefaultPipeline). However, for legacy PM, the pass is in the O0 pipeline (need to specify -fdebug-info-for-profiling). It is hard to tell if it is intentional (https://reviews.llvm.org/D36040). So my question is does it make sense to support such configuration (for parity with legacy PM and completeness) or we leave it as is? Any specific use cases for that?

-thanks
