| | | | llvm-svn: 80351
* llvm-mc: Support .zerofill emission.Daniel Dunbar2009-08-281-1/+21
| | | | | | - 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

* llvm-mc/Mach-O: Add MCCodeEmitter support, for encoding instructions.Daniel Dunbar2009-08-271-5/+24
| | | | | | - No relocations yet, of course. llvm-svn: 80235

* llvm-mc: Add symbol entries for undefined symbols used in .fill and .org.Daniel Dunbar2009-08-261-2/+10
| | | | llvm-svn: 80086
* llvm-mc/Mach-O: Set addresses for symbols.Daniel Dunbar2009-08-261-0/+1
| | | | llvm-svn: 80065
* llvm-mc: Improve indirect symbol support (add the indirect index table).Daniel Dunbar2009-08-261-0/+2
| | | | llvm-svn: 80059
* llvm-mc/Mach-O: Preliminary support for indirect symbols.Daniel Dunbar2009-08-241-4/+11
| | | | | | | | | - 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
* llvm-mc/Mach-O: Support symbol attributes.Daniel Dunbar2009-08-241-3/+80
| | | | | | | | - 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
* prune some redundant #includes.Chris Lattner2009-08-221-10/+9
| | | | llvm-svn: 79746
* llvm-mc/Mach-O: Improve symbol table support:Daniel Dunbar2009-08-221-1/+8
| | | | | | | | | | | | - Honor .globl. - Set symbol type and section correctly ('nm' now works), and order symbols appropriately. - Take care to the string table so that the .o matches 'as' exactly (for ease of testing). llvm-svn: 79740
* llvm-mc/Mach-O: Sketch symbol table support.Daniel Dunbar2009-08-221-4/+33
| | | | | | | | | | | - The only .s syntax this honors right now is emitting labels, and some parts of the symbol table generation are wrong or faked. - This is enough to get nm to report such symbols... incorrectly, but still. Also, fixed byte emission to extend the previous fragment if possible. llvm-svn: 79739
* llvm-mc: Clean up some handling of symbol/section association to be more correctDaniel Dunbar2009-08-221-6/+5
| | | | | | | | | (external was really undefined and there wasn't an explicit representation for absolute symbols). - This still needs some cleanup to how the absolute "pseudo" section is dealt with, but I haven't figured out the nicest approach yet. llvm-svn: 79733
* llvm-mc/Mach-O: Support .o emission for .org and .align.Daniel Dunbar2009-08-211-1/+3
| | | | llvm-svn: 79684
* llvm-mc/Mach-O: Support byte and fill value emission.Daniel Dunbar2009-08-211-4/+10
| | | | llvm-svn: 79652
* llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar2009-08-211-0/+170
- Together these form the (Mach-O) back end of the assembler. - MCAssembler is the actual assembler backend, which is designed to have a reasonable API. This will eventually grow to support multiple object file implementations, but for now its Mach-O/i386 only. - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API, e.g. converting the various directives into fragments, managing state like the current section, and so on. - llvm-mc will use the new backend via '-filetype=obj', which may eventually be, but is not yet, since I hear that people like assemblers which actually assemble. - The only thing that works at the moment is changing sections. For the time being I have a Python Mach-O dumping tool in test/scripts so this stuff can be easily tested, eventually I expect to replace this with a real LLVM tool. - More doxyments to come. I assume that since this stuff doesn't touch any of the things which are part of 2.6 that it is ok to put this in not so long before the freeze, but if someone objects let me know, I can pull it. llvm-svn: 79612
