[PATCH] D62062: [DWARF][RISCV] Add support for RISC-V relocations needed for debug info

[Luís Marques via Phabricator via llvm-commits]

luismarques updated this revision to Diff 201552.
luismarques added a comment.

- The test dumps the relocations using llvm-readobj instead of llvm-objdump.
- Changes the `objdump` flag, from `-source` to `--source`.

@MaskRay  I had already patched, built and tested LLD against this patch, but the LLD changes were not included in this patch because LLD was checked-out as a separate repo. It's just a ctor change, as seen bellow. I can't update that right now, as I'm on the move. If you think it's necessary I will update the Phabricator patch to also include those changes for official review, at a later date.
