--- Comment #23 from Alex Coplan <acoplan at gcc dot gnu.org> ---
Discovered by accident while working on a patch for trunk, but adding
-funroll-loops to the testcase in #c20 is enough to make the ICE trigger on the
trunk, too.
Testing a fix for trunk and a backport to 13 (to start with).
To reproduce on the trunk (t.c as in #c20):
$ gcc/xgcc -B gcc -c t.c -O3 -ffast-math -fopenmp -fstack-protector-strong
-funroll-loops
t.c: In function ‘dt_bilateral_splat.simdclone.1’:
t.c:25:1: error: unrecognizable insn:
