Evan Cheng 0c2544fd6b - Support inline asm 'w' constraint for 128-bit vector types. 
- Also support the 'q' NEON registers asm code.

Anton Korobeynikov 2522908653 Materialize global addresses via movt/movw pair, this is always better 
than doing the same via constpool:
1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2.
2. Load from constpool might stall up to 300 cycles due to cache miss.
3. Movt/movw does not use load/store unit.
4. Less constpool entries => better compiler performance.

This is only enabled on ELF systems, since darwin does not have needed
relocations (yet).

Anton Korobeynikov f24804413d Both Darwin as and GNU as violate ARM docs wrt printing of addrmode6 
alignment imm (in the same way). Fix asmprinting for non-darwin platforms.

David Greene 659c1a9d78 Move DebugInfo checks into EmitComments and remove them from 
target-specific AsmPrinters.  Not all comments need DebugInfo.

Re-enable the line numbers comment test.

Evan Cheng e034867587 Change Thumb1 address mode printing, instead of 
[r0, #2 * 4]
Now
[r0, #8]

This makes Thumb2 assembly more uniform and frankly the scale doesn't add much.

Anton Korobeynikov 226467d6a6 It turns out that the testcase in question uncovered subreg-handling bug. 
Add assert in asmprinter to catch such cases and xfail the tests.
PR is to be filled.

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.

Jakob Stoklund Olesen c7cfc94bcc Print out an informative comment for KILL instructions. 
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

llvm-svn: 84583
 2009-10-20 01:11:37 +00:00
Chris Lattner 43c5589a7e add support for external symbols. The mc instprinter can now handle 
reasonable code like Codegen/ARM/2009-02-27-SpillerBug.ll, producing 
identical output except for superior formatting of constant pool entries.

llvm-svn: 84582
 2009-10-20 00:56:16 +00:00
Chris Lattner 1b06acbd70 get fancy: support basic block operands. Yay for jumps.

Chris Lattner 2f69ed8f4c implement printSORegOperand, add lowering for the nasty and despicable MOVi2pieces :) 
llvm-svn: 84573
 2009-10-20 00:40:56 +00:00
Chris Lattner bd531262f8 handle addmode4 modifiers, fix a fixme in printRegisterList 
by ignoring all implicit regs when lowering.

 2009-10-19 22:49:00 +00:00
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 :)

llvm-svn: 84558
 2009-10-19 22:33:05 +00:00
Chris Lattner add5749ac8 add MCInstLower support for lowering ARM::PICADD, a pseudo op for pic stuffola. 
llvm-svn: 84553
 2009-10-19 22:23:04 +00:00
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.

llvm-svn: 84546
 2009-10-19 22:09:23 +00:00
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 , 

llvm-svn: 84543
 2009-10-19 21:57:05 +00:00
Chris Lattner 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 :)

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

	mov r7, sp
	sub sp, sp, #4
	mov r0, #0
	str r0, 

llvm-svn: 84535
 2009-10-19 21:21:39 +00:00
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,

llvm-svn: 84531
 2009-10-19 20:21:05 +00:00
Chris Lattner 71eb077c15 wire up skeletal support for having llc print instructions 
through mcinst lowering -> mcinstprinter, when llc is passed
the -enable-arm-mcinst-printer flag.  Currently this
is very "aborty".

llvm-svn: 84530
 2009-10-19 20:20:46 +00:00
Chris Lattner 296544e15f wire up ARM's printMCInst method. Now llvm-mc should be able to produce 
"something" when printing MCInsts, it will just be missing all the 
operand info.
