Bug ID: 124053
Summary: c2[3y]-imaginary-constants-7.c fails for
-march=armv8.1-m.main+mve.fp+fp.dp
Product: gcc
Version: 15.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
Both test cases fail with -march=armv8.1-m.main+mve.fp+fp.dp,
-march=armv8.1-m.main+mve.fp+fp and -march=armv8.1-m.main+mve.fp.dp (possibly
other permutations too).
The __mulhc3 intrinsic appears to be missing for arm-none-eabi.
