fbfd8552ab Return a better result from blocks. Closes issue #377
Blocks return in a copy of the result of their ending expression, not the
direct result of the ending expression, as that may be a local variable which
gets zeroed by drop_slot.

387a8888ee Fix get_os and get_arch
get_os and get_arch were failing to return a value in the error
case; they were also assuming that strings are indexed from 1. No
idea how they ever worked, but anyway, fixed.

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

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.

7647b838a1 Remove reserved word tests (since reserved words were removed)
Ping me if you disagree, but I think that in a language that's as
in-flux as rust currently is, it is silly to try and enforce a single
future-compatibility. The reserved words didn't work well with the
parser refactor, so I dropped them for the time being. We can,
eventually, bring them back as type-only reserved words.

ae26b775b4 Implement module namespaces

358a1aeec9 Keep resolve data in external hash table, rather than embedded defs
One step closer to removing fold and having a single, immutable AST.
Resolve still uses fold, because it has to detect and transform
expr_field expressions. If we go through on our plan of moving to a
different syntax for module dereferencing, the parser can spit out
expr_field expressions, and resolve can move to walk.

(I am truly sorry for the things I did in typestate_check.rs. I expect
we'll want to change that to walk as well in the near future, at which
point it should probably pass around a context record, which could
hold the def_map.)
