New Revision: 259230
URL: http://llvm.org/viewvc/llvm-project?rev=259230&view=rev
Log:
[CodeView] Implement .cv_inline_linetable
This support is _very_ rudimentary, just enough to get some basic data
into the CodeView debug section.
Left to do is:
- Use the combined opcodes to save space.
- Do something about code offsets.
