#14264: unregisterised GHC fails buid as: ghc-stage1: panic! (the 'impossible' happened): pprCLbl AsmTempLabel -------------------------------------+------------------------------------- Reporter: slyfox | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by angerman): While trying to build the iOS Cross Compiler, I've run into: ``` pprCLbl (AsmTempLabel {}) = panic "pprCLbl AsmTempLabel"` ``` Looks like the minor LLVM fix D4006, is not sufficient to resolve this either. In general it seems that the `AsmTempLabel` is tied rather directly to the NCG. And quite a few functions are partial/panicking for `AsmTempLabel` outside of the NCG :( -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14264#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
