* llvm-mc/Mach-O: Improve symbol table support:Daniel Dunbar2009-08-22
| | | | | | | | | | | | - 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

* llvm-mc: Clean up some handling of symbol/section association to be more correctDaniel Dunbar2009-08-22
| | | | | | | | | (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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79733 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar2009-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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
