57ffa2a487 Make the parser more careful about keywords 
Keywords are now only recognized in contexts where they are valid. The
lexer no longer recognizes them, all words are lexed as IDENT tokens,
that get interpreted by the parser.

58ec5d1654 Move capture checking into resolve.rs 
Drops capture.rs. The new algorithm also checks for captures function
arguments and obj fields.

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.

9c001af07c Implemented computing prestates and poststates for a few expression forms. 
The typestate checker (if it's uncommented) now correctly rejects a
trivial example program that has an uninitialized variable.

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.

6dc452335a rustc: Get tag variants from the crate metadata 2011-04-01 13:02:44 -07:00
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.
