a08a376d6e Make controlflow part of a function type 
Change ty_fn to have a controlflow field. A 'controlflow' is
essentially a bit of data that says whether or not this function
never returns to the caller (if it never returns, that means it calls
"fail" or another "never-returns" function on every control path).

Also add syntax for annotating functions that never return:

fn foo() -> ! {
   fail;
}

for example. Functions marked with ! implicitly have a result type of
ty_bot, which is a new type that this commit also adds.

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.

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.)

2b36e40c58 Ensure ann tags are actually kept around during typechecking 
This way, the tag assigned by the parser stays with the node.
I realize ann replacing is probably going away real soon, but

 * Remove a few blatant inefficiencies (import tables being recreated for
   every lookup, most importantly)

e3a68e235c Bring back "pred" syntax for writing predicates for check 
This commit reinstates the requirement that the predicate in a
"check" must be a manifest call to a special kind of function
declared with the new "pred" keyword instead of "fn". Preds must
have a boolean return type and can only call other preds; they
can't have any effects (as enforced by the typechecker).
The arguments to a predicate in a check expression must be
slot variables or literals.

aa25f22f19 Use different syntax for checks that matter to typestate 
This giant commit changes the syntax of Rust to use "assert" for
"check" expressions that didn't mean anything to the typestate
system, and continue using "check" for checks that are used as
part of typestate checking.

Most of the changes are just replacing "check" with "assert" in test
cases and rustc.

63e87c102d typestate_check can now handle expr_block, expr_if, and expr_binary 
(caveat for the latter: it assumes that binary operations are strict;
a TODO is to detect or and and and correctly reflect that they're lazy
in the second argument). I had to add an ann field to ast.block,
resulting in the usual boilerplate changes.

Test cases that currently work (if you uncomment the typestate pass
in the driver) (all these are under test/compile-fail):

fru-typestate
ret-uninit
use-uninit
use-uninit-2
use-uninit-3

d7e8818414 Further work on typestate. Handles expr_rec and expr_assign now. 
Also changed the ts_ann field on statements to be an ann instead,
which explains most of the changes.

As well, got rid of the "warning: no type for expression" error
by filling in annotations for local decls in typeck (not sure whether
this was my fault or not).

Finally, in bitv, added a clone() function to copy a bit vector,
and fixed is_true, is_false, and to_str to not be nonsense.

1af3174fe3 Move to single-uint file-position representation. 
This makes passing them around cheaper. There is now a table (see
front/codemap.rs) that is needed to transform such an uint into an
actual filename/line/col location.

Also cleans up the span building in the parser a bit.

1092bbfff0 Support for self-calls that take arguments. 
Nicer parsing of self-calls (expr_self_method nodes inside expr_call
nodes, rather than a separate expr_call_self) makes typechecking
tractable.  We can now write self-calls that take arguments and return
values (see: test/run-pass/obj-self-*.rs).

2e90bd94de Continued sketching out code for checking states against preconditions. 
It's still sketchy. I added a typestate annotation field to statements
tagged stmt_decl or stmt_expr, because a stmt_decl statement has a typestate
that's different from that of its child node. This necessitated trivial
changes to a bunch of other files all over to the compiler. I also added a
few small standard library functions, some of which I didn't actually end
up using but which I thought might be useful anyway.

4fc8de1969 Last pieces of self-call support. 
The last few pieces of the hack that lets us use trans.trans_call() to
translate self-calls, plus a fix for the parser buy that was
preventing self-call expressions from getting past parsing.
test/run-pass/obj-self.rs works now (as in it actually prints "hi!"
twice!).
 2011-04-05 16:26:31 -07:00
Lindsey Kuper
b8bb2e118e Further on the path toward self-awareness. 
Mostly:

  * Merciless refactoring of trans.rs so that trans_call can work for
    self-calls as well as other kinds of calls

Also:

  * Various changes to go with having idents, rather than exprs, in
    expr_call_self AST nodes
  * Added missing case for SELF token to token.to_str()

Tim Chevalier
3130348ee1 Started adding support for typestate checking. 
I added a new field to the ast "ann" type for typestate information.
Currently, the field contains a record of a precondition bit vector and
postcondition vector, but I tried to structure things so as to make
it easy to change the representation of the typestate annotation type.
I also had to add annotations to some syntactic forms that didn't have
them before (fail, ret, be...), with all the boilerplate changes
that that would imply.

The main call to the typestate_check entry point is commented out and
the actual pre-postcondition algorithm only has a few cases
implemented, though the overall AST traversal is there. The rest of
the typestate algorithm isn't implemented yet.
