The splitting pass currently doesn’t move cold symbols into a separate section. Is that affecting your results? On Darwin, we plan on using a symbol attribute to provide an ordering hint to the linker (see r352227, N_COLD_FUNC). vedant > On Jan 28, 2019, at 10:51 AM, Aditya K via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Very happy to see good results.

Hello, I’d like to give a status update to the community about the recently-added hot/cold splitting pass. I'll provide some motivation for the pass, describe its implementation, summarize recent/ongoing work, and share early results. # Motivation We (at Apple) have found that memory pressure from resident pages of code is significant on embedded devices. In particular, this pressure spikes
