--- Comment #5 from Hu Lin <lin1.hu at intel dot com> --- $ x86_64-w64-mingw32-gcc amxmovrs-asmatt-1.c -o a.exe -mconsole -c /tmp/ccwg5sNn.s: Assembler messages: /tmp/ccwg5sNn.s:49: Warning: operand 2 `%tmm1' implicitly denotes `%tmm0' to `%tmm1' group in `t2rpntlvwz0rst1' /tmp/ccwg5sNn.s:69: Warning: operand 2 `%tmm3' implicitly denotes `%tmm2' to `%tmm3' group in `t2rpntlvwz1rst1' On my side, the testcase passes compilation successfully, and the changes run without issue on the x86-64-linux-gnu. If your environments also prove the bug is fixed, I think I can submit the patch.
