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.
