Add Thumb encodings for REV instructions. llvm-svn: 120277 2010-11-29 08:42:50 +08:00			`@ RUN: llvm-mc -triple thumbv6-apple-darwin -show-encoding < %s \| FileCheck %s`
Add MC encodings for some Thumb instructions. Test for a few of them. The "bx lr" instruction cannot be tested just yet. It requires matching a "condition code", but adding one of those makes things go south quickly... llvm-svn: 119774 2010-11-19 09:33:10 +08:00			`.code 16`

Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almost certainly be made more generic. But it does allow us to parse something like: ldr r3, [r2, r4] correctly in Thumb mode. llvm-svn: 120408 2010-11-30 15:44:32 +08:00

ARM: fix thumb1 nop decoding In thumb1, NOP is a pseudo-instruction equivalent to mov r8, r8. However the disassembler should not use this alias. llvm-svn: 184703 2013-06-24 17:11:53 +08:00			`@ CHECK: mov r8, r8 @ encoding: [0xc0,0x46]`

Fix encoding and add parsing support for the arm/thumb CPS instruction: - Add custom operand matching for imod and iflags. - Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC from mnemonic. - While adding ".w" as an operand, don't change "Head" to avoid passing the wrong mnemonic to ParseOperand. - Add asm parser tests. - Add disassembler tests just to make sure it can catch all cps versions. llvm-svn: 125489 2011-02-14 21:09:44 +08:00			`cpsie aif`

ARM asm parser wasn't able to parse a "mov" instruction while in Thumb mode (only the "mov.w" variant). Now, when parsing "mov" in thumb mode, default to the Thumb 1 versions/encodings. llvm-svn: 132233 2011-05-28 07:46:09 +08:00
