Wed Jun 16 07:23:09 PDT 2004 malcolm * Fix a pattern-matching bug. Consider the following example: ------------------------------------------------ module Foo where newtype Blah = Blah Int deriving (Eq, Show) instance Num Blah where (Blah i) + (Blah j) = Blah (i + j) ... fromInteger x = Blah (fromInteger x) bar :: Blah -> Bool bar 0 = False bar _ = True ------------------------------------------------ nhc98 previously failed with: Fail: What? matchAltIf at 15:9 because the dictionary for (Num.fromInteger {dict:Blah} 0) in the pattern-match was being flattened to (Num.Blah.fromInteger 0), which made it impossible to later choose the right instance of (Eq.==). This fix ensures that fsExp knows whether it is in an expression context or a pattern-context, and for patterns it now refuses to flatten the dictionary. M ./src/compiler98/FixSyntax.hs -71 +69

It is correct that the first argument of the wrapper should indeed be a haskell function. (But as yet we still don't know how to generate code for wrappers...) M ./src/compiler98/Foreign.hs -9 +16

Sat Jun 12 07:20:41 PDT 2004 panne * Fixed prototype generation for functions returning a FunPtr, e.g.: foreign import ccall unsafe "foo" foo :: CString -> IO (FunPtr a) The former prototype was: extern NodePtr(*)() foo(void*); but this is not really C, we want: extern NodePtr(*foo(void*))(); The fix could probably need some review & cleanup => Malcolm? :-) M ./src/compiler98/Foreign.hs +6
