Evan Cheng b18525937c More consistent thumb1 asm printing.

Bob Wilson d95ccd6c4d Print VMOV (immediate) operands as hexadecimal values. Apple's assembler 
will not accept negative values for these.  LLVM's default operand printing
sign extends values, so that valid unsigned values appear as negative
immediates.  Print all VMOV immediate operands as hex values to resolve this.

Chris Lattner 60d5131653 Implement some hooks, make printOperand abort if unknown modifiers are 
present.

Chris Lattner 85ab670644 add supprort for the 'sbit' operand, MOVi apparently has one.

Chris Lattner 19c52201bd add support for instruction predicates.

Chris Lattner 2f69ed8f4c implement printSORegOperand, add lowering for the nasty and despicable MOVi2pieces :)

Chris Lattner 186c6b0834 lower the ARM::CONSTPOOL_ENTRY pseudo op, giving us constant pool entries 
like:

@ BB#1:
	.align	2
LCPI1_0:
	.long	L_.str-(LPC0+8)

Note that proper indentation of the label :)

Chris Lattner add5749ac8 add MCInstLower support for lowering ARM::PICADD, a pseudo op for pic stuffola.

Chris Lattner ef2979b1da add register list and hacked up addrmode #4 support, we now get this: 
_main:
	stmsp! sp!, {r7, lr}
	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0, [sp]
	ldr r0, LCPI1_0
	bl _printf
	ldr r0, [sp]
	mov sp, r7
	ldmsp! sp!, {r7, pc}

Note the unhappy ldm/stm because of modifiers being ignored.

Chris Lattner 7ddfdc4133 add addrmode2 support, getting us up to: 
_main:
	stm , 
	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0, [sp]
	ldr r0, LCPI1_0
	bl _printf
	ldr r0, [sp]
	mov sp, r7
	ldm ,

Chris Lattner 89d47205b5 add printing support for SOImm operands, getting us to: 
_main:
	stm , 
	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0,

Chris Lattner 93e3ef6536 wire up some basic printOperand goodness, giving us stuff like this before 
we abort:

_main:
	stm , 
	mov r7, sp
	sub sp, sp, 
	mov r0, 
	str r0,
