Subject: [PATCH 4/6] x86/MPX: bndmk, bndldx, and bndstx only allow a memory operand
Date: Tue, 08 Oct 2013 14:43:00 -0000 [thread overview]

[-- Attachment #1: Type: text/plain, Size: 1184 bytes --]
bndmk, bndldx, and bndstx only allow memory operands, so decoding should
use OP_M() instead of OP_E().

2013-10-08 Jan Beulich <jbeulich@suse.com>
* i386-dis.c (Mv_bnd): New.
(mod_table): Use it for bndmk, bndldx, and bndstx.
