* Continued sketching out code for checking states against preconditions.Tim Chevalier2011-04-064-0/+62
| | | | | | | | | 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.
* Started adding support for typestate checking.Tim Chevalier2011-04-011-0/+23
| | | | | | | | | | | | | | | 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.

* Extend stream functionalityMarijn Haverbeke2011-03-144-81/+129
| | | | | | Writer and reader streams now come with methods to write and read little-endian numbers. Whether that is the right place for such methods is debatable, but for now, that's where they live.
* Add basic file-system functionalityMarijn Haverbeke2011-03-1410-40/+86
