From 130b78b2bf16d5d89091db38374faef896360cf9 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 5 Dec 2011 21:05:39 +0900 Subject: x86: Fix instruction decoder to handle grouped AVX instructions For reducing memory usage of attribute table, x86 instruction decoder puts "Group" attribute only on "no-last-prefix" attribute table (same as vex_p == 0 case). Thus, the decoder should look no-last-prefix table first, and then only if it is not a group, move on to "with-last-prefix" table (vex_p != 0). However, current implementation, inat_get_avx_attribute() looks with-last-prefix directly. So, when decoding a grouped AVX instruction, the decoder fails to find correct group because there is no "Group" attribute on the table. This ends up with the mis-decoding of instructions, as Ingo reported in http://thread.gmane.org/gmane.linux.kernel/1214103 This patch fixes it to check no-last-prefix table first even if that is an AVX instruction, and get an attribute from "with last-prefix" table only if that is not a group.

it's not correct. The 'X' stands for: Memory addressed by the DS:rSI register pair (for example, MOVS, CMPS, OUTS, or LODS). On the other hand 'Y' means (also see the ae byte entry for SCASB): Memory addressed by the ES:rDI register pair (for example, MOVS, CMPS, INS, STOS, or SCAS).
