Duncan P. N. Exon Smith f8e316d9f7 ADCE: Remove debug info intrinsics in dead scopes ... During ADCE, track which debug info scopes still have live references from the code, and delete debug info intrinsics for the dead ones. These intrinsics describe the locations of variables (in registers or stack slots). If there's no code left corresponding to a variable's scope, then there's no way to reference the variable in the debugger and it doesn't matter what its value is. I add a DEBUG printout when the described location in an SSA register, in case it helps some trying to track down why locations get lost. However, we still delete these; the scope itself isn't attached to any real code, so the ship has already sailed. llvm-svn: 264800		2016-03-29 22:57:12 +00:00
