From fc6b2cceb4c16b8b33390b779d1ed64c84b1e954 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Sat, 4 Aug 2007 20:17:31 -0700 Subject: [PATCH] X86: Make fixed register operands ignore register index extensions from the REX prefix. The only cases where this was the correct behavior are now handled with the "B" operand type, and doing things this way was breaking some instructions, notably a shift. --HG-- extra : convert_revision : 072346d4f541edaceba7aecc26ba8d2cd756e481 --- src/arch/x86/isa/specialize.isa | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/arch/x86/isa/specialize.isa b/src/arch/x86/isa/specialize.isa index b5f51ab58..690061de7 100644 --- a/src/arch/x86/isa/specialize.isa +++ b/src/arch/x86/isa/specialize.isa @@ -138,9 +138,9 @@ let {{ #Figure out what to do with fixed register operands #This is the index to use, so we should stick it some place. if opType.reg in ("A", "B", "C", "D"): - env.addReg("INTREG_R%sX | (REX_B << 3)" % opType.reg) + env.addReg("INTREG_R%sX" % opType.reg) else: - env.addReg("INTREG_R%s | (REX_B << 3)" % opType.reg) + env.addReg("INTREG_R%s" % opType.reg) Name += "_R" elif opType.tag == "B": # This refers to registers whose index is encoded as part of the opcode -- 2.30.2
