[PATCH] D156505: [AArch64][ELF] Support R_AARCH64_AUTH_ABS64 static relocation

[Daniil Kovalev via Phabricator via llvm-commits]

kovdan01 updated this revision to Diff 552562.
kovdan01 added a comment.

Propose additional unary/binary operator tests like `1 + sym at AUTH(ia,42) + 1`, `sym at AUTH(ia,0) + sym at AUTH(ia,0)`:

- Parsing assembly code
- Producing errors when emitting object file

To make the latter work properly, altered `EvaluateSymbolicAdd`. Without the change, incorrect relocations were emitted instead of producing an error. @MaskRay would be glad if you could look through this before landing since I consider these changes non-trivial.
