[PATCH] D60913: [GVN+LICM] Use line 0 locations for better crash attribution

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Using zero on non-call locations might bloat the line table a fair bit. May be better to let those locations get flow-on from whatever other instructions are around?

At least that, I think, is the current policy of "merge debug locations", is it not?

Perhaps we need a similar utility that can be kept in the same place (as merge debug locations)/enforce the same policy for hoisted locations.
