[PATCH] D101523: [DebugInfo] Fix updateDbgUsersToReg to support DBG_VALUE_LIST

[Stephen Tozer via Phabricator via llvm-commits]

StephenTozer updated this revision to Diff 341688.
StephenTozer added a comment.

Fixed an issue with the previous implementation of this fix: the `CopyDbgUsers` vectors would sometimes contain duplicate elements, causing errors when we attempt to replace the same debug operand multiple times. This has been fixed by making it into a SmallSet instead of a SmallVector, although we still convert to SmallVector before updating to avoid changing the MRI interface.
