Mon Nov 27 09:07:09 PST 2000 malcolm * Fix bug with local fixity decls. These worked ok in a `let' block, but not in a `where' block. It turns out that the precedence was being computed at the wrong time - after the scoped expression, rather than before. M ./src/compiler98/Rename.hs -3 +6

patch applied (hat): Replaced the old ugly and inefficient pretty printer by a new efficient one.

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.
