.align 3, 0x90
instead of,
  .align 3, 144

 2009-08-31 08:06:59 +00:00
Daniel Dunbar 6a715dccdf llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported for now. 
- Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency).

llvm-svn: 80484
 2009-08-30 06:17:16 +00:00
Daniel Dunbar 2a2459a291 llvm-mc: .lsym is more unsupported than unimplemented, pending a use case appearing. 
Also, all one of the file level flags are implemented.

llvm-svn: 80352
 2009-08-28 07:08:47 +00:00
Daniel Dunbar 2701eee0ad llvm-mc: Support .comm emission. 
llvm-svn: 80351
 2009-08-28 07:08:35 +00:00
Daniel Dunbar 42a39d038a llvm-mc: Support .zerofill emission. 
- I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences.

llvm-svn: 80347
 2009-08-28 05:49:21 +00:00

Daniel Dunbar c7c5f9fa86 llvm-mc/Mach-O: Add MCCodeEmitter support, for encoding instructions. 
- No relocations yet, of course.

llvm-svn: 80235
 2009-08-27 08:17:51 +00:00
Daniel Dunbar c4f0e7e28d llvm-mc: Print encodings after the instruction, and only when we have an asm 
printer.

llvm-svn: 80233
 2009-08-27 07:58:57 +00:00
Daniel Dunbar 212b6d8a57 Add {MCInst,MCOperand}::{print,dump} 
llvm-svn: 80231
 2009-08-27 07:57:12 +00:00
Daniel Dunbar 9cefb135a5 Update CMake 
llvm-svn: 80195
 2009-08-27 02:08:37 +00:00
Daniel Dunbar 81cb753298 llvm-mc: Tweak MCCodeEmitter skeleton. 
llvm-svn: 80193
 2009-08-27 01:34:22 +00:00
Daniel Dunbar 65105174a6 Sketch TargetRegistry support for MCCodeEmitter abstract interface. 
- Of course, nothing actually can provide this interface yet.

llvm-svn: 80188
 2009-08-27 00:51:57 +00:00
Daniel Dunbar 47f11ac5b5 Try to make MSVC just a little happier. 
llvm-svn: 80187
 2009-08-27 00:38:04 +00:00
Daniel Dunbar e73b267301 llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table. 
- I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).

llvm-svn: 80162
 2009-08-26 22:13:22 +00:00
Daniel Dunbar e2697738a4 llvm-mc/Mach-O: Set .subsections_via_symbols flag properly. 
llvm-svn: 80144
 2009-08-26 21:22:22 +00:00
Daniel Dunbar c4581eaca8 llvm-mc/Mach-O: Add support for relocations. 
- I haven't really tried to find the "right" way to store the fixups or apply
   them, yet. This works, but isn't particularly elegant or fast.

 - Still no evaluation support, so we don't actually ever not turn a fixup into
   a relocation entry.

llvm-svn: 80089
 2009-08-26 13:58:10 +00:00
Daniel Dunbar a9eeb78ed5 llvm-mc/Mach-O: Move symbol indices into the MCSymbolData structure. 
llvm-svn: 80088
 2009-08-26 13:57:54 +00:00
Daniel Dunbar c1710a04ba llvm-mc: Add symbol entries for undefined symbols used in .fill and .org. 
llvm-svn: 80086
 2009-08-26 13:57:37 +00:00
Daniel Dunbar ffda9eb31a llvm-mc: Change MCContext value table to take const MCSymbol*s. 
llvm-svn: 80079
 2009-08-26 09:16:57 +00:00
Daniel Dunbar 066d0f93bf llvm-mc/Mach-O: Add section padding where needed (to align the next section). 
Also, simplify some of Mach-O writer code which can now use section addresses.

llvm-svn: 80067
 2009-08-26 04:13:32 +00:00
Daniel Dunbar aef5317edd llvm-mc/Mach-O: Set addresses for symbols. 
llvm-svn: 80065
 2009-08-26 02:48:04 +00:00
Daniel Dunbar c2c0bf961f llvm-mc: Improve indirect symbol support (add the indirect index table). 
llvm-svn: 80059
 2009-08-26 00:18:21 +00:00
Bill Wendling a9f56a686c Revert last patch. We need to put this into TargetLowering. There will be a lot 
of EH stuff going into there, so we can wait to add them all then.

llvm-svn: 80036
 2009-08-25 21:31:39 +00:00
Daniel Dunbar 5a07d6a9c6 llvm-mc: Add statistic for number of fragments emitted by the assembler. 
llvm-svn: 80033
 2009-08-25 21:10:45 +00:00
Bill Wendling dd14b4a77a Add the #include here. 
llvm-svn: 80032
 2009-08-25 21:09:50 +00:00
Bill Wendling 485591273c Add a target asm info hook to specify that particular bits of data in the FDE 
should be forced to 32-bits (.long) even on 64-bit architectures. Darwin wants
these bits to be 64-bits (.quad). However, other platforms may disagree.

This is just the info right now and is part of a work-in-progress which needs
this. We'll add the actual *use* of this soon.

llvm-svn: 80024
 2009-08-25 20:21:17 +00:00
Daniel Dunbar 582d61026d llvm-mc/Mach-O: Preliminary support for indirect symbols. 
- The indirect table itself isn't being filled in yet.

 - This isn't factored properly and is rather FIXMEd, but at the moment I'm more
   focused on figuring out what it needs to do.

llvm-svn: 79910
 2009-08-24 11:56:58 +00:00
Daniel Dunbar 04a1158d13 llvm-mc/Mach-O: Support symbol attributes. 
- This is mostly complete, the main thing missing is .indirect_symbol support
   (which would be straight-forward, except that the way it is implemented in
   'as' makes getting an exact .o match interesting).

llvm-svn: 79899
 2009-08-24 08:40:12 +00:00
Daniel Dunbar d341e781da llvm-mc: Tweak undefined symbol handling. 
llvm-svn: 79898
 2009-08-24 08:39:57 +00:00
Chris Lattner 06fa176862 prune the #includes in raw_ostream.h by moving a 
member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

llvm-svn: 79885

Chris Lattner e9a75a6654 rename TAI -> MAI, being careful not to make MAILJMP instructions :)

 2009-08-22 21:43:10 +00:00
Chris Lattner 054574666a rename COFFMCAsmInfo -> MCAsmInfoCOFF, likewise for darwin. 
llvm-svn: 79773
 2009-08-22 21:03:30 +00:00
Chris Lattner 2b9f0d100b move the MCAsmInfo .cpp/.h files into the right 
directories and rename them.

llvm-svn: 79768
 2009-08-22 20:58:17 +00:00
Chris Lattner 7b26fce23e Rename TargetAsmInfo (and its subclasses) to MCAsmInfo.
