* Make the big switch: Change MCSectionMachO to represent a section *semantically*Chris Lattner2009-08-101-5/+4
| | | | | | | | | | | | | | | | 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? llvm-svn: 78547
* sink the 'name' and 'isdirective' state out of MCSection into its derived ↵Chris Lattner2009-08-081-1/+1

* switch this to create coff sections for now, it doesn't really matter for Chris Lattner2009-08-081-1/+1

* Add TargetRegistry::lookupTarget.Daniel Dunbar2009-07-261-1/+4
| | | | | | | | | | | | | | - This is a simplified mechanism which just looks up a target based on the target triple, with a few additional flags. - Remove getClosestStaticTargetForModule, the moral equivalent is now: lookupTarget(Mod->getTargetTriple, true, false, ...); - This no longer does the fuzzy matching with target data (based on endianness and pointer width) that getClosestStaticTargetForModule was doing, but this was deemed unnecessary. llvm-svn: 77111

| | | | | | | - This provides the AsmParser interface to the target specific assembly parsers. llvm-svn: 76453

| | | | | | | | | | | | - Don't print "Parsing" in front of every message. - Take additional "type" argument which is prepended to the message (with ": ") if given. - Update clients to print errors (warnings) as: <filename>:<line number>: error(warning): ... llvm-svn: 74489
* Basic .s parsing for .asci[iz], .fill, .space, {.byte, .short, ... }Daniel Dunbar2009-06-241-0/+4
| | | | | | | - Includes some DG tests in test/MC/AsmParser, which are rather primitive since we don't have a -verify mode yet. llvm-svn: 74139
* add trivial support for passing label definitions through the MCStreamer.Chris Lattner2009-06-241-2/+1
