Chris Lattner 00fa4b67e6 zap the ARM version of PrintGlobalVariable, which I missed. 
llvm-svn: 93863
 2010-01-19 06:08:15 +00:00
Chris Lattner f8a128a1a8 some cleanups 
llvm-svn: 93853
 2010-01-19 04:53:18 +00:00
Chris Lattner dccbb28bca add a bool for whether .lcomm takes an alignment instead of basing this on "isdarwin". 
llvm-svn: 93852
 2010-01-19 04:48:20 +00:00
Chris Lattner 6a160517a0 hoist handling of external globals and special globals up to common code. 
This makes a similar code dead in all the other targets, I'll clean it up
in a bit.

This also moves handling of lcomm up before acquisition of a section,
since lcomm never needs a section.

 2010-01-19 04:39:15 +00:00
Chris Lattner e9d28b19cf move production of .reference directives for static ctor/dtor list on 
darwin into common code.

llvm-svn: 93849
 2010-01-19 04:34:02 +00:00
Chris Lattner 35474ca4c4 use BSSLocal classifier to identify 'lcomm' data instead of 
duplicating the logic (differently) in lots of different targets.

 2010-01-19 04:21:20 +00:00
Chris Lattner 70f0c33ec8 now that elf weak bss symbols are handled correctly, simplify a bunch of code. 
llvm-svn: 93845
 2010-01-19 03:13:44 +00:00
Chris Lattner 5b585f8b1a introduce a section kind for common linkage. Use this to slightly 
simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

llvm-svn: 93843
 2010-01-19 02:48:26 +00:00
Chris Lattner aa1f4fd0ed change an accessor to a predicate. 
llvm-svn: 93839
 2010-01-19 02:13:06 +00:00
Chris Lattner 1d371882b6 Cleanup handling of .zerofill on darwin: 
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

Jim Grosbach e7b52f2e87 Minor cleanup for jump table printing. Need a reference, not a pointer, for 
printing via <<. Otherwise we just print the pointer value.

llvm-svn: 93777
 2010-01-18 22:01:39 +00:00
Chris Lattner 8b5d55ed06 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

llvm-svn: 93695
 2010-01-17 21:43:43 +00:00
Chris Lattner 555ceabe64 rename GetPrivateGlobalValueSymbolStub -> GetSymbolWithGlobalValueBase, 
and add an explicit ForcePrivate argument.

Switch FunctionEHFrameInfo to be MCSymbol based instead of string based.

llvm-svn: 93646
 2010-01-16 18:37:32 +00:00
Chris Lattner 719e908e7c MCize a bunch more stuff, eliminating a lot of uses of the mangler 
and CurrentFnName.

llvm-svn: 93594
 2010-01-16 00:21:18 +00:00
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. 
llvm-svn: 93582
 2010-01-15 23:31:55 +00:00
Chris Lattner 45400336ab mc'ize a bunch of symbol stuff, eliminating std::strings. 
llvm-svn: 93578
 2010-01-15 23:26:49 +00:00
Chris Lattner 91687f6e28 add a AsmPrinter::GetGlobalValueSymbol and GetExternalSymbolSymbol 
helper method, use it to simplify some code.

llvm-svn: 93575
 2010-01-15 23:18:17 +00:00
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.
