================
Comment at: llvm/tools/llvm-profgen/CSPreInliner.cpp:82
+ // profile from run to run.
+ uint64_t ColdCountThreshold = ProfileSummaryBuilder::getColdCountThreshold(
+ (Summary->getDetailedSummary()));
----------------
I kinda remember we discussed offline that you tested for trimming hot edges vs trimming cold edges, how about other threshold, like trimming non-hot edges, or it's just a balance, then I'm wondering if other value can perform better, in that case we can tune a new threshold?
