#10347: Spurious "unused constructor" warning with Coercible -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): Meh. Good point. I think this might signal a re-evaluation of the whole `DefUse` thing, which is quite complicated to manage, and isn't paying its way. For top-level-bound things, something more like `tcg_used_rdrnames` (but for `Name`s) might work better.
