[PATCH] D103539: WIP: try to repair RISCV handling of paired relocations

[Saleem Abdulrasool via Phabricator via llvm-commits]

compnerd updated this revision to Diff 351202.
compnerd added a comment.

3 failures left now.  KI:

- 6B relocations are not implemented
- debug_line references aren't correctly emitted

One thing to note is that this seems to improve the generation of the eh_frame, which is important for enabling relaxation without negatively impacting unwinding.
