Fix Trac #3219: type of a record update

Record updates are amazingly hard to typecheck right.  This is one place
where GHC's policy of typechecking the original source is much harder than
desugaring and typechecking that!

Anyway, the bug here is that to compute the 'fixed' type variables I was
only looking at one constructor rather than all the relevant_cons

Test is typecheck/should_compile/T3219, which GHC 6.10 barfs on (with Lint).

-fPIC merely to link to shared libs however Haskell shared libs do not

referenced statically because it cannot be copied by the static linker.

Improve error messages for type functions

Following a suggestion of Claus Reinke, this patch improves the error
messages involving type functions.  Here's the relevant note from TcTyFuns.

Note [Non-injective type functions]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It's very confusing to get a message like
     Couldn't match expected type `Depend s'
            against inferred type `Depend s1'
so pp_open_tc adds:
       NB: `Depend' is a (non-injective) type function

Currently we add this independently for each argument, so we also get
     Couldn't match expected type `a'
            against inferred type `Dual (Dual a)'
       NB: `Dual' is a (non-injective) type function
which is arguably redundant.  But on the other hand, it's probably
a good idea for the programmer to know the error involves type functions
so I've left it in for now.  The obvious alternative is to only add
this NB in the case of matching (T ...) ~ (T ...).

13 years agoEquality constraint solver is now externally pure
Manuel M T Chakravarty [Mon, 27 Apr 2009 14:03:16 +0000 (14:03 +0000)]
Equality constraint solver is now externally pure
- This patch changes the equality constraint solver such that it does not
  instantiate any type variables that occur in the constraints that are to be
  solved (or in the environment).  Instead, it returns a bag of type bindings.
- If these type bindings (together with the other results of the solver) are
  discarded, solver invocation has no effect (outside the solver) and can be
  repeated (that's imported for TcSimplifyRestricted).
- For the type bindings to take effect, the caller of the solver needs to
  execute them.
- The solver will still instantiate type variables thet were created during
  solving (e.g., skolem flexibles used during type flattening).
