From d241b91073165f99fe404d9b38c65f03835ecaf4 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 7 Oct 2019 08:38:01 +0200 Subject: [PATCH] x86/Intel: correct MOVSD and CMPSD handling First and foremost the EsSeg attribute was misplaced for CMPSD. Then both it and MOVSD were lacking Dword on both of their operands. Finally string insns with multiple operands and requiring use of ES: had the wrong operand number reported in the diagnostic. --- gas/config/tc-i386.c | 4 +-- gas/testsuite/gas/i386/i386.exp | 2 ++
