Re: Writing / Compiling with Primops / Primtypes

MagicHash definitely helped but I also had to adjust some thinking. Here is my path back to sanity: {-# LANGUAGE MagicHash #-} import GHC.Prim import GHC.Exts main = do print (eqChar# 'a'# 'b'#) Phew … Thank You for the start! Paul Monday Parallel Scientific, LLC. paul.mon...@parsci

Re: Writing / Compiling with Primops / Primtypes

Are you compiling with -XMagicHash? It doesn't really change program semantics - it merely allows you to add '#' to the end of an identifier, which GHC typically uses to indicate unboxed/primitive types (technically it also introduces a few extra literal forms too.) Note the wording of the users gu
