[PATCH] D132994: [RISC-V][HWASAN] Don't explicitly load GOT entry to call hwasan mismatch routine

[Alexey Baturo via Phabricator via llvm-commits]

smd added a comment.

I think one of possible solutions for the problem mentioned above might be the following:

- mark __hwasan_tag_mismatch_v2 as .variant_cc directly in asm file
- add support for reading/dumping .variant_cc as emitDirectiveVariantPCS does
- remove setting ELF::STO_RISCV_VARIANT_CC for  __hwasan_tag_mismatch_v2 in RISCVAsmPrinter.cpp

Supposedly (2) should be implemented/committed as a separate patch before this one. I believe I do have it, so I might publish it for the review.

@jrtc27 @luismarques  what do you think of that?
