Bug ID: 126961
Summary: [16/17 Regression] incorrect codegen on several
gcc.dg/vect/pr104116-*.c tests with SVE2
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: tnfchris at gcc dot gnu.org
Reporter: tnfchris at gcc dot gnu.org
Target Milestone: ---
Target: aarch64*
SVE2 implements IFN_DIV_POW2 and because of this when enabled we see these
failures:
