#10852: ghc 7.8.4 on arm - panic: Simplifier ticks exhausted ---------------------------------------+------------------------------ Reporter: andrewufrank | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: arm Operating System: Linux | Architecture: arm Type of failure: Compile-time crash | Test Case: Blocked By: | Blocking: Related Tickets: #5642, #9675 | Differential Rev(s): Wiki Page: | ---------------------------------------+------------------------------ Comment (by andrewufrank): the problem in pureMD5 seems to be in the part {{{ #ifdef FastWordExtract getNthWord n b = inlinePerformIO (unsafeUseAsCString b (flip peekElemOff n . castPtr)) #else getNthWord :: Int -> B.ByteString -> Word32 getNthWord n = right . G.runGet G.getWord32le . B.drop (n * sizeOf (undefined :: Word32)) where right x = case x of Right y -> y #endif -- {-# INLINE getNthWord #-} }}} i have removed the inline pragma and it compiles. the armhf is not FastWordExtract (at least not set in the cabal) and thus uses code which is typically for the intel processor not used. i hope this helps to fix the problem. thank you! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10852#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
