* 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: Improve handling of implicit alignment for magic section directivesDaniel Dunbar2009-08-21
| | | | | | | | | (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: In a .fill directive, still honor .align even if invalid maximum bytesDaniel Dunbar2009-08-21
| | | | | | | count is given (this matches 'as'). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79683 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc: Accept .fill size of 8.Daniel Dunbar2009-08-21

* llvm-mc: Various section parsing fixes.Daniel Dunbar2009-08-21
| | | | | | | | | | | | | | | | - 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

* llvm-mc: Sketch parsing for .file, .line, and .loc. No streamer hooks for theseDaniel Dunbar2009-08-11

* llvm-mc: Fix darwin .section parsing. It was skipping the section name and a ','Daniel Dunbar2009-08-11
| | | | | | | | (and outputting a diagnostic pointing at the wrong place), all of which lead to much confusion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78637 91177308-0d34-0410-b5e6-96231b3b80d8

* Make the big switch: Change MCSectionMachO to represent a section *semantically*Chris Lattner2009-08-10
| | | | | | | | | | | | | | | | | | instead of syntactically as a string. This means that it keeps track of the segment, section, flags, etc directly and asmprints them in the right format. This also includes parsing and validation support for llvm-mc and "attribute(section)", so we should now start getting errors about invalid section attributes from the compiler instead of the assembler on darwin. Still todo: 1) Uniquing of darwin mcsections 2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h] 3) there are a few FIXMEs, for example what is the syntax to get the S_GB_ZEROFILL segment type? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78547 91177308-0d34-0410-b5e6-96231b3b80d8

* Added Mac OS X assembler style conditional assembly. I may come back and see ifKevin Enderby2009-08-07
| | | | | | | | | I can clean this up a bit more and do way with the TheCondState and just use the top element on the TheCondStack if not empty. Also may tweak the code around ParseConditionalAssemblyDirectives() to simplify the AsmParser code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78423 91177308-0d34-0410-b5e6-96231b3b80d8

* Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API asKevin Enderby2009-07-20
| | | | | | | | | | the parsing of the .dump and .load should be done in the assembly parser and not have any need for an MCStreamer API.
