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.

llvm-svn: 123929
2011-01-20 18:32:09 +00:00
Bruno Cardoso Lopes 33461ecc82 - Use a more appropriate name for Owen's ARM Parser isMCR hack since the same operands can be present
in cdp/cdp2 instructions. Also increase the hack with cdp/cdp2 instructions.
- Fix the encoding of cdp/cdp2 instructions for ARM (no thumb and thumb2 yet) and add testcases for t
hem.

Owen Anderson dac7a0174e When matching asm operands, always try to match the most restricted type first.
Unfortunately, while this is the "right" thing to do, it breaks some ARM
asm parsing tests because MemMode5 and ThumbMemModeReg are ambiguous.  This
is tricky to resolve since neither is a subset of the other.

XFAIL the test for now.  The old way was broken in other ways, just ways
we didn't happen to be testing, and our ARM asm parsing is going to require
significant revisiting at a later point anyways.

Evan Cheng d4a5c05c97 Completed :lower16: / :upper16: support for movw / movt pairs on Darwin.
- Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first.
- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.

Evan Cheng 965b3c7323 Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

Jason W Kim 9c5b65d289 1. Support ELF pcrel relocations for movw/movt:
R_ARM_MOVT_PREL and R_ARM_MOVW_PREL_NC.
2. Fix minor bug in ARMAsmPrinter - treat bitfield flag as a bitfield, not an enum.
3. Add support for 3 new elf section types (no-ops)

Daniel Dunbar 9d944b3fcc McARM: Add more hard coded logic to SplitMnemonicAndCC to also split out the
carry setting flag from the mnemonic.

Note that this currently involves me disabling a number of working cases in
arm_instructions.s, this is a hopefully short term evil which will be rapidly
fixed (and greatly surpassed), assuming my current approach flies.

Bob Wilson fa27a8621c Add Neon VCVT instructions for f32 <-> f16 conversions.
Clang is now providing intrinsics for these and so we need to support them
in the backend.  Radar 8068427.

Kevin Enderby 4886cc8be7 Add some more MC tests for ARM arithmetic instructions that update or don't
update the condition codes.  These come from my test generator and are just
the ones that MC currently assembles correctly.

2010-12-14 17:37:16 +00:00
Kevin Enderby 3164a346e6 Add support for parsing ARM arithmetic instructions that update or don't update
the condition codes.  Where the ones that do have an 's' suffix and the ones
that don't don't have the suffix.  The trick is if MatchInstructionImpl() fails
we try again after adding a CCOut operand with the correct value and removing
the 's' if present.  Four simple test cases added for now, lots more to come.

Bill Wendling 811c936ed5 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.

Bill Wendling 945b776b6e 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
