Summary: [15/16 Regression] FAIL:
gcc.dg/vect/complex/fast-math-complex-mls-float.c
scan-tree-dump vect "Found COMPLEX_ADD_ROT270"
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
After r15-3128-gde1923f9f4d534, the test case
gcc.dg/vect/complex/fast-math-complex-mls-float.c no longer generate the
expected string "Found COMPLEX_ADD_ROT270" in the vect dump.

Should the test case be adjusted to xfail if the pattern is seen instead or is
this a compiler error?
