Chris Lattner 7fec180909 add a version of AsmPrinter::printVisibility that takes an MCSymbol. 
llvm-svn: 93587
 2010-01-15 23:38:51 +00:00
Chris Lattner 6394a6e285 use MCSymbol instead of getMangledName() in all cases except one.

Chris Lattner 45400336ab mc'ize a bunch of symbol stuff, eliminating std::strings.

Chris Lattner 91687f6e28 add a AsmPrinter::GetGlobalValueSymbol and GetExternalSymbolSymbol 
helper method, use it to simplify some code.

Chris Lattner ede8ad45bc upgrade and MC'ize a few uses of makeNameProper. 
llvm-svn: 93310
 2010-01-13 08:08:33 +00:00
Chris Lattner 209aecad0c change Mangler::makeNameProper to return its result in a SmallVector 
instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

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.

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 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 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".

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.

Bob Wilson 3b51560ae4 Revise ARM inline assembly memory operands to require the memory address to 
be in a register.  The previous use of ARM address mode 2 was completely
arbitrary and inappropriate for Thumb.  Radar 7137468.
