--- Comment #2 from Bo Wang <wangbopku15 at gmail dot com> --- Following the issue 105139, I reproduce the assembler version as follows: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ $ cat vmovw.s vmovw %xmm0, %xmm1 $ as -v --64 vmovw.s GNU assembler version 2.34 (x86_64-linux-gnu) using BFD version (GNU Binutils for Ubuntu) 2.34 vmovw.s: Assembler messages: vmovw.s:1: Error: no such instruction: `vmovw %xmm0,%xmm1' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
