[PATCH] D58453: [DebugInfo][CGP] Limit placeDbgValues movement of dbg.value intrinsics

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope added a comment.

It is definitely about time that we also refresh the documentation. One thing that is lacking is documentation of the backend parts (currently https://llvm.org/docs/SourceLevelDebugging.html talks about intrinsics like dbg.value etc, but shouldn't it also cover DBG_VALUE pseudo instruction). Afaict dbg.value and DBG_VALUE aren't exactly the same. And I think even DBG_VALUE might have some different properties depending on where in the llc pipeline we are (e.g. if the location only is valid up to the end of the BB or not).
