encoder functions.

Jim Grosbach 4a0c2d73c3 Convert ARM::MOVi2pieces to a true pseudo-instruction and expand it in 
the ARMExpandPseudos pass rather than during the asm lowering.

Chris Lattner 5d6f6a061b add simple support for addrmode5 operands, allowing 
vldr.64 to work.  I have no idea if this is fully right, but 
it is in the right direction.

Jim Grosbach 505607e4c6 PLD, PLDW, PLI encodings, plus refactor their use of addrmode2.

Evan Cheng ff310737e5 Re-commit 117518 and 117519 now that ARM MC test failures are out of the way.

Evan Cheng e2c211c1b9 Revert 117518 and 117519 for now. They changed scheduling and cause MC tests to fail. Ugh.

Evan Cheng ff1c862f8e - Assign load / store with shifter op address modes the right itinerary classes. 
- For now, loads of [r, r] addressing mode is the same as the
  [r, r lsl/lsr/asr #] variants. ARMBaseInstrInfo::getOperandLatency() should
  identify the former case and reduce the output latency by 1.
- Also identify [r, r << 2] case. This special form of shifter addressing mode
  is "free".

llvm-svn: 117519
 2010-10-28 01:49:06 +00:00
Evan Cheng 59bbc545e0 Shifter ops are not always free. Do not fold them (especially to form 
complex load / store addressing mode) when they have higher cost and
when they have more than one use.

Jim Grosbach 338de3ee56 Refactor ARM STR/STRB instruction patterns into STR{B}i12 and STR{B}rs, like 
the LDR instructions have. This makes the literal/register forms of the
instructions explicit and allows us to assign scheduling itineraries
appropriately. rdar://8477752

 2010-10-27 23:12:14 +00:00
Owen Anderson fadb951e5b Provide correct encodings for NEON vcvt, which has its own special immediate encoding 
for specifying fractional bits for fixed point conversions.

rdar://8477752.

Jim Grosbach a92801b695 Since I parameterized this bit, I should probably actually use said parameter.

 2010-10-26 23:58:04 +00:00
Jim Grosbach 1e4d9a17c2 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

Jim Grosbach efc066829b Make a few more bits of some simple instructions explicit. nop, yield, wfe, 
wfi, sel, sev and bkpt. All would disassemble properly before, but more
explicitness is good, especially with the integrated assembler coming in
