This includes shifts by immediate, which use bits 3-5 of the ModRM byte as an opcode extension. With the exception of 128-bit shifts, they are implemented using gvec. This also covers VZEROALL and VZEROUPPER, which use the same opcode as EMMS. If we were wanting to optimize out gen_clear_ymmh then this would be one of the starting points. The implementation of the VZEROALL and VZEROUPPER helpers is by Paul Brook. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
