From 8cc8a1d8367f87c722c44d7584303f90b22ee6d0 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Sat, 25 Feb 2012 11:11:42 -0800 Subject: Add support for warning on invalid LOCK prefixes Add an LOCK flag to the instruction template, and make the presence of a LOCK prefix trigger a warning if it is not set. Simplify the LOCK and HLE logic by hard-coding the knowledge that operand 0 has to be memory. Signed-off-by: H.
