* Revert "DebugInfo: Move type units into the debug_types section with ↵David Blaikie2013-12-113-45/+9
| | | | | | | | | | | | appropriate comdat grouping and type unit headers" This reverts commit r197073. The test seems to be failing on some buildbots for unknown reasons. Reverting until I can figure that out. If anyone's got a reproduction (.s and .o together would be great) - I'd really appreciate it. llvm-svn: 197079

| | | | | | | | | | | comdat grouping and type unit headers This commit does not complete the type units feature - there are issues around fission support (skeletal type units, pubtypes/pubnames) and hashing of some types including those containing references to types in other type units. llvm-svn: 197073

* DebugInfo: Move unit begin/end labels into the unitDavid Blaikie2013-12-062-22/+29
| | | | | | | | This removes another case of spooky action at a distance (building the same label names in multiple places creating an implicit dependency between those places) and helps pave the way for type units. llvm-svn: 196617
* DebugInfo: Include the section and start-of-section label in the unitDavid Blaikie2013-12-064-16/+59
| | | | | | | This is a precursor to moving type units into the correct (debug_types) section with comdat groups and full type unit headers. llvm-svn: 196615
* DwarfDebug: Walk skeletons during fission pubtypes/pubnames emissionDavid Blaikie2013-12-061-10/+10
| | | | | | | | | | | This more accurately represents the actual walk - pubnames/pubtypes are emitted into the .o, not the .dwo, and reference the skeletons not the full units. Use the newly established ID->index invariant to lookup the underlying full unit to retrieve its public names and types. llvm-svn: 196601
* DebugInfo: Ensure unit IDs (for non-skeletal units) match thein index in the ↵David Blaikie2013-12-062-12/+9
| | | | | | | | | | | | | | | | | | | list This simplifies reasoning about the code and enables simple navigation from a skeleton to its full unit. (currently there are no type unit skeletons, so the skeleton list doesn't have the same ID == index property) Eventually we should get rid of this ID and just store the labels we need as the IDs are allowing this code to create difficult to manage/understand associations (loops over non-skeletal units are implicitly referencing their skeletal units during pub* emission, for example). It may be necessary to have some kind of skeleton->full unit association and a more direct pointer or similar device would be preferable than an index. llvm-svn: 196600

* DebugInfo: Remove unused start/end labels for the debug_abbrevs sectionDavid Blaikie2013-12-042-8/+4
| | | | | | | | | | Since we always emit only one abbrevation section (shared by all the compilation units in this module) there's no need for a separate label at the start of each one (and we weren't using the CU ID anyway, so there really was only one label). Use the section label instead and drop the wholely unused debug_abbrev_end label. llvm-svn: 196394
* DebugInfo: Avoid recreating matching labels in disparate places.David Blaikie2013-12-041-20/+16
