#10462: GHCi doesn't work Any and missing RealWorld foreign prim imports -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: bug | Status: new Priority: low | Milestone: Component: GHCi | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by hsyl20): I don't think your first example works as expected. It type checks but the calling convention is silently ignored and replaced by the default CCall one (see #3336 and "convToABI" in compiler/ghci/LibFFI.hsc). The other examples fail because "generateCCall" from compiler/ghci/ByteCodeGen.hs shouldn't be called at all for primops and there are errors when parameters are pushed (your first case) or when parameters are converted into types understandable by libffi (second case). I attach a patch with an additional check which fails sooner and in a nicer way (similarily to #1257). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10462#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
