[PATCH] D32695: [XRay][compiler-rt] Support patching/unpatching specific functions

[Dean Michael Berris via Phabricator via llvm-commits]

dberris created this revision.

This change allows us to patch/unpatch specific functions using the
function ID. This is useful in cases where implementations might want to
do coverage-style, or more fine-grained control of which functions to
patch or un-patch at runtime.

Depends on https://reviews.llvm.org/D32693.
