#13495: ghc-stage1: panic! (the 'impossible' happened) creating cross compiler for PPC ----------------------------------------+------------------------------- Reporter: jms | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.0.2 Resolution: | Keywords: Operating System: Linux | Architecture: powerpc Type of failure: Building GHC failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ----------------------------------------+------------------------------- Comment (by rwbarton): Let's keep this open as it pointed out that GHC fails to ignore `-fllvm` in an unregisterized compiler. I don't have time to fix this right now but it looks like we just need to check for `HscLlvm` as well in this snippet near the end of `DynFlags`: {{{#!hs | hscTarget dflags == HscAsm && platformUnregisterised (targetPlatform dflags) = loop (dflags { hscTarget = HscC }) "Compiler unregisterised, so compiling via C" }}} (Maybe it would even be better to merge the targets `HscAsm` and `HscLlvm`, since they are equivalent for most purposes besides actually building the build pipeline?) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13495#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
