A dbg.declare may not be in entry block, even if it is referring to an incoming argument. However, It is appropriate to emit DBG_VALUE referring to this incoming argument in entry block in MachineFunction.

lit needs a linter ...

these was just one line of a file. Explicitly set the eol-style property on the
files to try and ensure this fix stays.

Fixes Thumb2 ADCS and SBCS lowering: <rdar://problem/9275821>.
t2ADCS/t2SBCS are now pseudo instructions, consistent with ARM, so the
assembly printer correctly prints the 's' suffix.

Fixes Thumb2 adde -> SBC matching to check for live/dead carry flags.

Fixes the internal ARM machine opcode mnemonic for ADCS/SBCS.
Fixes ARM SBC lowering to check for live carry (potential bug).

Sometimes it is better to split per block, and we missed those cases.

fix bugs exposed by the gcc dejagnu testsuite:
1. The load may actually be used by a dead instruction, which
   would cause an assert.
2. The load may not be used by the current chain of instructions,
   and we could move it past a side-effecting instruction. Change
   how we process uses to define the problem away.

print out ldr, not ldr.n.

rdar://problem/9267772

llvm-svn: 130008

On x86 this allows to fold a load into the cmp, greatly reducing register pressure.
  movzbl	(%rdi), %eax
  cmpl	$47, %eax
->
  cmpb	$47, (%rdi)

This shaves 8k off gcc.o on i386. I'll leave applying the patch in README.txt to Chris :)
