Revision d523b8325857e4cd6f298ec9f356432676c81edb authored by Steven Johnson on 13 March 2021, 00:54:23 UTC, committed by GitHub on 13 March 2021, 00:54:23 UTC
(1) Both the 'deprecated' and new, non-deprecated variants existed back to at least LLVM10, and the deprecated variant was commented as deprecated at that point as well; the change in LLVM13 is that they are now annotated with LLVM_ATTRIBUTE_DEPRECATED so we get compiler warnings (and thus errors).

(2) The fixes are simply replicating what the old, deprecated methods did internally.
