[Xen-devel] [PATCH v3 05/18] x86emul: support {,V}{,U}COMIS{S,D}

Signed-off-by: Jan Beulich --- v3: Ignore VEX.l. Add fic.exn_raised constraint to invoke_stub() use. v2: Add missing RET to stub. Generate #UD (instead of simply failing) when VEX.l is disallowed. --- a/xen/arch/x86/x86_emulate/x86_emulate.c +++
