[llvm-dev] Adding utility/debugging passes upstream

[Anna Thomas via llvm-dev]

Hi,

I was wondering what’s the community guideline for adding new passes which are solely used for debugging/analysis purposes? Can this be in the upstream llvm, or such passes are more suitable in local downstream repository?

In our case, the ‘utility (ease-of-analysis)’ pass is for transformation done by RewriteStatepointsForGC (RS4GC). Note that right now, RS4GC is not enabled in the opt pipeline upstream, but the utility pass would be for downstream users who have RS4GC enabled in their opt pipeline. 


Thanks,
Anna
