* llvm-mc: Improve handling of implicit alignment for magic section directivesDaniel Dunbar2009-08-212-19/+21
| | | | | | | | | (e.g., .objc_message_refs). - Just emit a .align when we see the directive; this isn't exactly what 'as' does but in practice it should be ok, at least for now. See FIXME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79697 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar2009-08-217-4/+1255
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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
* llvm-mc: Various section parsing fixes.Daniel Dunbar2009-08-212-44/+84
| | | | | | | | | | | | | | | | - Add missing flags for various Objective-C sections. - Fix names for [non_]lazy_symbol_pointer (these are misspelled in the manual). - .symbol_stub does not have the self modifying code flag set (this appears to be wrong in the manual?). - Add implicit alignment values; not yet used. Also, call MCStreamer::Finish at the end of a successful parse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79611 91177308-0d34-0410-b5e6-96231b3b80d8
