[PATCH] D102712: BPF: Add more relocation kinds

[Yonghong Song via Phabricator via llvm-commits]

yonghong-song added a comment.

- add a test for ExecutionEngine/RuntimeDyld for added BPF relocation case. Without the patch in RuntimeDyldELF.cpp, the test will crash
- rename R_BPF_64_ALLOC32 to R_BPF_64_NODYLD32.
- added @MaskRay as the reviewer
- remaining known issues to be resolved:
  - can BPF backend use FK_SecRel_4 for R_BPF_64_64?
  - Is the relocation name R_BPF_64_NODYLD32 okay or we could have a better one?
