Bug ID: 100457
Summary: [meta bug] Enabling O2 vectorization in GCC 12
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: crazylht at gmail dot com
CC: hjl.tools at gmail dot com
Target Milestone: ---
This metabug is used to track all the O2 vectorization issues.
We're trying to enable vectorization in O2 for GCC12. To do that, we need to
make there's no regression comparing -O2 -ftree-vectorize
-fvect-cost-model=very-cheap to plain -O2, or those regressions are acceptable.
