Bug ID: 125231
Summary: [16/17 Regression] VE in 729.abc_r with -O3
-ffast-math -flto
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: needs-bisection, needs-source
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
On x86_64 needs -march=x86-64-v2 or higher. r16-5962 works, r16-6736 fails.
Not bisected further, not analyzed whether it's invalid (aka, -ffast-math).
0069: mcml_mcml_miter : i/o =58565/ 1 lat = 0 and =
894210 lev = 851 power = 7028
mcml_mcml_miter : i/o =58565/ 1 lat = 0 and =
894210 lev = 851 power = 7026

0072: mcml_mcml_miter : i/o =58565/ 1 lat = 0 and =
894210 lev = 851 power = 7028
mcml_mcml_miter : i/o =58565/ 1 lat = 0 and =
894210 lev = 851 power = 7026
^
so the difference is 7028 vs. 7026
