malcolm: Wed Nov 22 17:49:00 CET 2000 nhc/src/compiler98 FFITrans.hs Foreign.hs TokenId.hs TokenInt.hs Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv1015 Modified Files: FFITrans.hs Foreign.hs TokenId.hs TokenInt.hs Log Message: (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.
