Jim Grosbach 36acc8e984 Thumb2 assembly parsing and encoding for NOP.W. 
llvm-svn: 139740
 2011-09-14 21:26:25 +00:00
Jim Grosbach b861b2b475 Tests for Thumb2 AND (immediate) instruction.

Jim Grosbach adb29b6dbb Fix predicates for Thumb co-processor instructions. 
They're all Thumb2 only, not just some of them. More refactoring cleanup
coming.

Jim Grosbach 16896325a6 ARM Thumb2 asm syntax optional destination operand for binary operators. 
When the destination operand is the same as the first source register
operand for arithmetic instructions, the destination operand may be omitted.

For example, the following two instructions are equivalent:
and r1, #ff
and r1, r1, #ff

Jim Grosbach a6f7a1efcc ARM Assembly support for Thumb mov-immediate. 
Correctly parse the forms of the Thumb mov-immediate instruction:
  1. 8-bit immediate 0-255.
  2. 12-bit shifted-immediate.

The 16-bit immediate "movw" form is also legal with just a "mov" mnemonic,
but is not yet supported. More parser logic necessary there due to fixups.

Bruno Cardoso Lopes 394f516d16 Fix ssat and ssat16 encodings for ARM and Thumb. The bit position value 
must be encoded decremented by one. Only add encoding tests for ssat16
because ssat can't be parsed yet.

Bruno Cardoso Lopes f170f8bff6 Add asm parsing support w/ testcases for strex/ldrex family of instructions

 2011-03-24 21:04:58 +00:00
Bruno Cardoso Lopes 9cd43977c3 Add assembly parsing support for "msr" and also fix its encoding. Also add 
testcases for the disassembler to make sure it still works for "msr".

 2011-02-18 19:45:59 +00:00
Bruno Cardoso Lopes 90d1dfe4c6 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.

Bruno Cardoso Lopes 4bd612384a Fix the encoding of QADD/SUB, QDADD/SUB. While qadd16, qadd8 use "rd, rn, rm", 
qadd and qdadd uses "rd, rm, rn", the same applies to the 'sub' variants. This
is described in ARM manuals and matches the encoding used by the gnu assembler.
