From: "tnfchris at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug ipa/103734] New: IPA-CP opportunity for imagick in SPECCPU 2017 Date: Wed, 15 Dec 2021 12:14:02 +0000 [thread overview] Message-ID: <bug-103734-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103734 Bug ID: 103734 Summary: IPA-CP opportunity for imagick in SPECCPU 2017 Product: gcc Version: 12.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: ipa Assignee: unassigned at gcc dot gnu.org Reporter: tnfchris at gcc dot gnu.org CC: hubicka at gcc dot gnu.org, marxin at gcc dot gnu.org Target Milestone: --- When using --param ipa-cp-eval-threshold=1 --param ipa-cp-unit-growth=20 on imagick the hot functions MorphologyApply and GetVirtualPixelsFromNexus get replaced by specialized versions that are much smaller and faster. Some other benchmarks like leela also get very small uplifts but the imagick one is worth 14%. Both flags seem to be needed.
