#12132: Type representations missing for promoted boxed tuples -------------------------------------+------------------------------------- Reporter: bgamari | Owner: bgamari Type: bug | Status: closed Priority: normal | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2279 Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): that it does handle promoted tuple data cons.
