Subject: [PATCH 0/8] Simplify byte/word opcode pair decode
Date: Mon, 23 Aug 2010 14:06:09 +0300 [thread overview]
Message-ID: <1282561577-24491-1-git-send-email-avi@redhat.com> (raw)
Many x86 instructions come in pairs - byte and word variants where bit 0
of the opcode determines operand size. Use this to simplify the decode
tables.
Avi Kivity (8):
KVM: x86 emulator: support byte/word opcode pairs
KVM: x86 emulator: simplify ALU block (opcodes 00-3F) decode flags
KVM: x86 emulator: simplify string instruction decode flags
KVM: x86 emulator: simplify instruction decode flags for opcodes
80-8F
KVM: x86 emulator: simplify instruction decode flags for opcodes
A0-AF
KVM: x86 emulator: simplify instruction decode flags for opcodes
C0-DF
KVM: x86 emulator: simplify instruction decode flags for opcodes
E0-FF
KVM: x86 emulator: simplify instruction decode flags for opcodes 0F
00-FF
