[PATCH] D15386: [sanitizer] [msan] VarArgHelper for AArch64

[Adhemerval Zanella via llvm-commits]

zatrazz updated this revision to Diff 42436.
zatrazz added a comment.

Changes from previous version:

- Fixed some typos and comments wording.
- Fixed the AArch64VrEndOffset value to correct one (it was based on general purpose register side, instead of the VR stat address which is aligned to 16 bytes).
- Changed the way the address plus offset is calculate from a addition to a GEP instruction. This fixes some issues when using opt -msan on the testcase (it complains about using different types on the addition).
- Added a testcase.
