--- Comment #2 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
It's rejected with 2.38:

$ as -v --64 -o a-pr105139.o a-pr105139.s
GNU assembler version 2.38 (x86_64-suse-linux) using BFD version (GNU Binut=
ils;
openSUSE Tumbleweed) 2.38.20220304-3
a-pr105139.s: Assembler messages:
a-pr105139.s:92: Error: operand type mismatch for `vmovw'

Let me bisect GAS.=
