These results seemsto be consistant and match the results Teresa got with her simpleheuristic. Some benchmarks got slower but I think they are justnoisy (mcf, xalancbmki, omnetpp)- running the benchmarks again withmore iterations to confirm. Geomean of all benchmarks including the noisy oneswere about +0.02%.I see much better improvement on google branch with Easwaran patchfor pgo callsite inlining (the inliner actually inline those big functions)Over all I see +0.5% improvement, and I get +8.65% on povray.So I guess we will see much bigger change when Easwaran patch will land(it depends on new pass manager), but it is still worth putting this to trunkbefore it.Implementation details changes:- Removed CallsiteCount.- ProfileCount got replaced by Hotness- hot-import-multiplier is set to 3.0 for now,didn't have time to tune it up, but I see that we get most of the interestingfunctions with 3, so there is no much performance difference with higher, andbinary size doesn't grow as much as with 10.0.Reviewers: eraman, mehdi_amini, tejohnsonSubscribers: mehdi_amini, llvm-commitsDifferential Revision: https://reviews.llvm.org/D24638llvm-svn: 282437 List of files: /llvm-project-15.0.7/llvm/test/Transforms/FunctionImport/Inputs/hotness_based_import.ll Mon, 26 Sep 2016 20:37:32 +0000 Piotr Padlewski <piotr.padlewski@gmail.com>
