Please don’t. I’ll send out updated patches.

You need to introduce a new constant type like DSOLocalEquivalent or NoCFIValue.

Do you by any chance have some timeline about this? Maybe @atrosinenko can help you with updating the patches so the upstreaming process could go faster? AFAIK, he already has your branch rebased onto mainline.

Here is the rebased branch: https://github.com/access-softek/llvm-project/tree/rebased-ptrauth. Some tests might fail as it is work-in-progress.
