[PATCH] D58334: [LLVM-C] Add bindings to create macro debug info

[Jean-Bapiste Lepesme via Phabricator via llvm-commits]

Jiboo updated this revision to Diff 187216.
Jiboo added a comment.

Mybad, llvm::dwarf::MacinfoRecordType (in llvm/BinaryFormat/Dwarf.h) isn't generated using Dwarf.def, so I just used the same values for another enum in llvm-c/DebugInfo.h.
The values in llvm::dwarf::MacinfoRecordType won't move as they are defined by the DWARFv4 standard (Figure 39. Macinfo Type Encodings, at page 194/325), so it is safe to static_cast it from the new LLVMDWARFMacinfoRecordType to MacinfoRecordType.
