I tried to reduce the test with more care and I think it's a new `gcc-15` regression related to constant folding in vector shifts. Filed https://gcc.gnu.org/PR115161 And somewhat related: > 972 - HwyShuffle4TestGroup/HwyShuffle4Test.TestAllPer4LaneBlockShuffle/SS= E2 # GetParam() =3D 16384 (Subprocess aborted) from the #comment1 is a separate `gcc-15` regression related to vector rotations: https://gcc.gnu.org/PR115146. It's (pending) fix does not help t= he `TestAllF2IPromoteTo/SSE2` above. Thus it looks like all the bugs are independent and require separate fixes.=
