llvm/test/MC/Disassembler, branch master

The purpose of the patch is to fix the syntax of ARM mrc and mrc2 instructions when they are used to write to the APSR. In this case, the destination operand should be APSR_nzcv, and the encoding of the target should be 0b1111 (same as for PC). In pre-UAL syntax, this form used the PC register as a textual target. This is still allowed for backward compatibility.

s tightens up the encoding description for ARM post-indexed ldr instructions. All instructions in this class have bit 4 cleared. It turns out that there is a test case for this, but it was marked XFAIL.

ARM: Fix encoding of hint instruction for Thumb.

2013-04-26T17:54:54Z

"hint" space for Thumb actually overlaps the encoding space of the CPS instruction. In actuality, hints can be defined as CPS instructions where imod and M bits are all nil. Handle decoding of permitted nop-compatible hints (i.e. nop, yield, wfi, wfe, sev) in DecodeT2CPSInstruction. This commit adds a proper diagnostic message for Imm0_4 and updates all tests.

ARM: Correct printing of pre-indexed operands.

2013-04-12T18:47:25Z

According to the ARM reference manual, constant offsets are mandatory for pre-indexed addressing modes. The MC disassembler was not obeying this when the offset is 0. It was producing instructions like: str r0, [r1]!. Correct syntax is: str r0, [r1, #0]!. This change modifies the dumping of operands so that the offset is always printed, regardless of its value, when pre-indexed addressing mode is used.
