[llvm-dev] Similar Function Merging

[Phipps, Alan via llvm-dev]

Hello! I heard "similar function merging" discussed at the Developers' Meeting a couple of weeks ago, and I wanted to look into this more for potential code size reduction as it focused on merging functions with small differences rather than identical function merging.

Is https://reviews.llvm.org/D85616 the latest review for this pass?  Any ideas on when it will be able to be upstreamed?

Can this pass be run even when -ffunction-sections is enabled?  Also, I understand this pass is most useful during LTO, when there is better knowledge as to the functions that are kept in the final link.

Thanks!
