2009-08-26llvm-mc/Mach-O: Add section padding where needed (to align the next section).Daniel Dunbar
Also, simplify some of Mach-O writer code which can now use section addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80067 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-25llvm-mc: Add statistic for number of fragments emitted by the assembler.Daniel Dunbar

2009-08-24llvm-mc/Mach-O: Preliminary support for indirect symbols.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79910 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24llvm-mc/Mach-O: Support symbol attributes.Daniel Dunbar
- 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79899 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-24prune the #includes in raw_ostream.h by moving a Chris Lattner
member out of line. ftostr is not particularly speedy, so that method is presumably not perf sensitive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79885 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-22llvm-mc/Mach-O: Improve symbol table support:Daniel Dunbar
- 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79740 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-22llvm-mc/Mach-O: Sketch symbol table support.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79739 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-22llvm-mc/Mach-O: Move more logic for writing the Mach-O file into the writerDaniel Dunbar
class, and kill off MCSectionData::FileOffset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79735 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-22llvm-mc: Rename / redefine MCFragment::FileOffset to MCFragment::Offset (theDaniel Dunbar
section offset). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79734 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-21llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79612 91177308-0d34-0410-b5e6-96231b3b80d8
