[PATCH] D31663: [LLD][ELF] Account for range thunk that has drifted out of range

[Peter Smith via Phabricator via llvm-commits]

peter.smith created this revision.

Adding range extension thunks to an OutputSection alters some InputSection VAs, including the VAs of the thunks themselves. In rare cases a call to a thunk that was valid on pass N, is not valid in some later pass N + K. We account for this by detecting if a caller can't reach the thunk, reseting the relocation to the original and recreating the Thunk.
