* Make the big switch: Change MCSectionMachO to represent a section *semantically*Chris Lattner2009-08-101-11/+258
| | | | | | | | | | | | | | | | | | 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

* sink the 'name' and 'isdirective' state out of MCSection into its derived ↵Chris Lattner2009-08-081-7/+20

* 1. Make MCSection an abstract class.Chris Lattner2009-08-081-5/+109
| | | | | | | | | | | 2. Move section switch printing to MCSection virtual method which takes a TAI. This eliminates textual formatting stuff from TLOF. 3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and TLOFELF::AtIsCommentChar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78510 91177308-0d34-0410-b5e6-96231b3b80d8

* Change SectionKind to be a property that is true of a *section*, itChris Lattner2009-08-011-5/+6
| | | | | | | | | | | | | | | | | | | | should have no state that is specific to particular globals in the section. In this case, it means the removal of the "isWeak" and "ExplicitSection" bits. MCSection uses the new form of SectionKind. To handle isWeak, I introduced a new SectionInfo class, which is SectionKind + isWeak, and it is used by the part of the code generator that does classification of a specific global. The ExplicitSection disappears. It is moved onto MCSection as a new "IsDirective" bit. Since the Name of a section is either a section or directive, it makes sense to keep this bit in MCSection. Ultimately the creator of MCSection should canonicalize (e.g.) .text to whatever the actual section is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77803 91177308-0d34-0410-b5e6-96231b3b80d8
