b42bb2cff2 Two tests that the typechecker correctly unifies type arguments in patterns with their expected tag types 2011-05-16 16:59:30 -07:00
Tim Chevalier
971b5d5151 Started adding support for return checking and non-returning function annotations 
* Reorganized typestate into several modules.

* Made typestate check that any function with a non-nil return type
  returns a value. For now, the check is a warning and not an error
  (see next item).

* Added a "bot" type (prettyprinted as _|_), for constructs like be, ret, break, cont, and
  fail that don't locally return a value that can be inspected. "bot"
  is distinct from "nil". There is no concrete syntax for _|_, while
  the concrete syntax for the nil type is ().

* Added support to the parser for a ! annotation on functions whose
  result type is _|_. Such a function is required to have either a
  fail or a call to another ! function that is reached in all control
  flow paths. The point of this annotation is to mark functions like
  unimpl() and span_err(), so that an alt with a call to err() in one
  case isn't a false positive for the return-value checker. I haven't
  actually annotated anything with it yet.

* Random bugfixes:

* * Fixed bug in trans::trans_binary that was throwing away the
    cleanups for nested subexpressions of an and or or
    (tests: box-inside-if and box-inside-if2).

** In typeck, unify the expected type arguments of a tag with the
   actual specified arguments.

f77c5ba512 rustc: Wait until generic glue is actually emitted to define it as internal 
The verifier was not liking this when generating unoptimized bitcode. Per LLVM
docs it is not valid for function declarations to be marked internal, but
their implementations may be.

So that the type parser won't go off and try to parse a vec
type when it sees vec::init_op.

5679f5c55e 'with' no longer a token; whitespace police. 
Plus renaming the anonymous objects test to a more descriptive name,
and XFAILing it because it doesn't work yet.

cd31d5d532 More anon obj work; whitespace police in middle::fold 
Passing args to middle::fold::fold_expr_anon_obj by reference to be
consistent with the other folds; adding a dummy fold_expr_anon_obj to
typeck to be filled in later.
