| | | | | | | | | | | | | | | | | | | | | | | | 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. Originally committed as r197073 and reverted in r197079. Recommitted as r197197 to reproduce the failure and reverted as r197199 Turns out there was unstable ordering in the type unit dumping code. Fixed by using MapVector in DWARFContext to store the debug_types comdat sections. Recommitted as r197210 with a fix to dumping and reverted as r197211 because I was a bit gun shy and thought I saw a failure that turned out to be unrelated. So here we go - once more with feeling! \o/ llvm-svn: 197275

Originally committed as r197073 and reverted in r197079. This commit originally got jumbled up with another build-breaking commit and I can't find the failures I thought this caused anymore. Recommitting to hopefully get some clean buildbot results to work from. I have a sneaking suspicion there's unstable output in the comdat group output of MCStreamer... llvm-svn: 197197
* On ELF and COFF treat linker_private like private.Rafael Espindola2013-12-111-1/+1
| | | | | | | | The linkers on these systems don't have anything special to do with these symbols. Since the intent is for them to be absent from the final object, just treat them as private. llvm-svn: 197080

| | | | | | | | | | | | 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

* DwarfDebug/Unit: Remove another case of label recreation by storing the ↵David Blaikie2013-12-092-6/+14

* 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

* DwarfDebug: Avoid unnecessary abbreviation lookup when emitting DIEsDavid Blaikie2013-12-052-18/+16

* DwarfDebug: Unconditionalize trivial asm commentsDavid Blaikie2013-12-041-10/+5
