0dae1cbf1c AL is an optional mnemonic extension for always, except in IT instructions. 
Add printMandatoryPredicateOperand() PrintMethod for IT predicate printing.

41ad1905c9 sink handling of target-independent machine instrs (other 
than DEBUG_VALUE :(  ) into the target indep AsmPrinter.cpp
file.   This allows elimination of the 
NO_ASM_WRITER_BOILERPLATE hack among other things.

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

bd531262f8 handle addmode4 modifiers, fix a fixme in printRegisterList 
by ignoring all implicit regs when lowering.

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 :)

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.

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 ,

889a6217fa add jump tables, constant pools and some trivial global 
lowering stuff.  We can now compile hello world to:

_main:
	stm , 
	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0, 
	ldr r0, 
	bl _printf
	ldr r0, 
	mov sp, r7
	ldm , 

Almost looks like arm code :)

89d47205b5 add printing support for SOImm operands, getting us to:

	str r0,

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,
