(The decoding of L/R fixity from an Int was wrong in SExp). In hat-trail: * Fix the problem of textual overflow in the error/output panes.

malcolm: Tue May 21 13:08:23 CEST 2002 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv1672/src/compiler98 Modified Files: Extract.hs Log Message: Do `extractExp' on field update expressions, to ensure that local let-expressions get their arity recorded. This avoids a compiler failure later on. Test case that previously broke the compiler: module Apa where data A = A{ field :: Bool } apa = A{ field = let s = False in s }

malcolm: Mon May 20 19:51:35 CEST 2002 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv22765 Modified Files: FixSyntax.hs Log Message: Bugfix for negative literal number patterns, where the instance of Num to be used is at a user-defined type. Must ensure that the Num dictionary is passed through to the pattern-compilation phase (for selection of Eq.==), rather than selecting the negate method from it here and immediately discarding the dict.

malcolm: Mon May 20 16:16:18 CEST 2002 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv21684 Modified Files: TraceTrans.hs Log Message: In hat-trans, if a module has no export list, produce an export list containing only the stuff that should be exported. This avoids the problem of overlapping definitions of internally-generated identifiers (e.g. source positions) in a multi-module program. A little bit of a hack but should work. (Also noticed that a default declaration should always be deleted by the transformation).

The fix is to remember the most recent Hidden node encountered, and if we trip over it again, stop the cycle and return the Hidden.
