[PATCH] D117394: [BOLT] Fix AARCH64 registers aliasing

[Vladislav Khmelevsky via Phabricator via llvm-commits]

yota9 added a comment.

@fhahn The problem was not found during bolt usage, i.e. wrong output, but accidentally while I was investigating the aarch64 indirect branch support level. Currently the bolt uses tests like "input file" -> "output file",  but I don't have an example of input file where the problem might occur and I don't know the way to test particular function from bolt internals. Maybe the reviewers will give me a hint on this
