patch applied (hat): Changed definition of syntax tree
by Malcolm Wallace 10 Oct '06

10 Oct '06

Tue Nov 28 10:13:35 PST 2000 olaf * Changed definition of syntax tree from data Fun id = Fun [Pat id] [(Exp id,Exp id)] (Decls id) data Alt id = Alt (Pat id) [(Exp id,Exp id)] (Decls id) to data Fun id = Fun [Pat id] (Rhs id) (Decls id) data Alt id = Alt (Pat id) (Rhs id) (Decls id) data Rhs id = Unguarded (Exp id) | Guarded [(Exp id,Exp id)] -- the list has at least one element so that lots of artificial True guards can be omitted. This change obviously required small changes in many modules. It is unclear if more or less space is required now. The prelude module DErrNo.hs seems to require more space during compilation now.

Thu Nov 23 09:24:40 PST 2000 olaf * Replaced the old ugly and inefficient pretty printer by a new efficient one. Hence modules PPLib, PPSyntax and StrSyntax have been removed. They are replaced by PrettyLib and PrettySyntax. There are some new compiler options to set output width, indentation of nesting and qualification of identifier. For printing NewType and NT still the module Nice is used, that will have to be changed in the future.

Wed Nov 22 08:49:00 PST 2000 malcolm * (1) An earlier change introduced a wrapper function allowing 'foreign import's always to have a pure (non-I/O) type. We now do the same thing for 'foreign export's, creating a wrapper that uses 'unsafePerformIO'. (FFITrans.hs) (2) So the generation of the C-code for foreign imports and exports can be simplified substantially now. (Foreign.hs) (3) We also take this opportunity to reverse the earlier decision to handle tupled result types in the compiler. Simply treat them like any other non-primitive type - i.e. pass it as a single heap value. (Tools like GreenCard can do some extra work here if needed.) (4) Improve the printing of type names in reports about foreign calls.
