Bug ID: 397089
Summary: [PATCH] Incorrect decoding of three-register
vmovss/vmovsd opcode 11h
Product: valgrind
Version: 3.13.0
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: tomastr...@gmx.com
Target Milestone: ---
Created attachment 114267
--> https://bugs.kde.org/attachment.cgi?id=114267&action=edit
Proposed patch
vmovss/vmovsd xmm1, xmm2, xmm3 using opcode 11h was decoded exactly the same as
opcode 10h, swapping the xmm1 and xmm3 arguments. This leads to all kinds of
floating point software going crazy under Valgrind because of assignments
suddenly working in the wrong direction.
