2011-04-06Continued sketching out code for checking states against preconditions.Tim Chevalier-132/+343
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.

prestates and poststates. Still a long ways away.
2011-04-05Last pieces of self-call support.Lindsey Kuper-6/+37
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!).
2011-04-05Further on the path toward self-awareness.Lindsey Kuper-118/+99
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()
2011-04-05FIx native wrapper generation to handle more arg types.Graydon Hoare-3/+23
2011-04-05Oops -- if we're going to use the pretty-printer, we need it to work.Lindsey Kuper-0/+5
2011-04-05Knocking out a quick fixme: pretty-printing exprs in error messages.Lindsey Kuper-2/+3

2011-04-04A trivial documentation commit.Lindsey Kuper-1/+1

2011-04-04Make box prefix operator and box type carry mutability flag.Graydon Hoare-14/+17
2011-04-03Begin comparing vectors from the correct addressBrian Anderson-1/+1
Start at the first element instead of the address of the vector.
2011-04-02Change rust_vec to have a 16-byte header, to 16-byte-align vec-body data. ↵Graydon Hoare-7/+14
Major perf win.

2011-04-02Add more tests for alt expressionsBrian Anderson-2/+111
2011-04-02Add FIXMEs around type handling in trans_if, trans_altBrian Anderson-0/+2
2011-04-02Join the results of alt arms so alt can be used as an expression.Brian Anderson-13/+18
Un-XFAIL expr-alt.rs.
2011-04-02Make join_results branch into the join block even when only one edge is live.Brian Anderson-6/+0
I don't don't totally understand the implications of this but it makes the behavior consistent for all live edges, which is going to make joining the arms of an alt expression work correctly.
2011-04-02Fail on non-exhaustive alt matchesBrian Anderson-3/+3
2011-04-02Terminate fail blocks by making their ends unreachable.Brian Anderson-3/+3
This will make implementing default alt arms simpler.

2011-04-01added Mac .DS_Store directory to .gitignoreTim Chevalier-0/+1
2011-04-01Started adding support for typestate checking.Tim Chevalier-235/+814
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.

2011-03-31Initialize the alloca used to retrieve boxed block results to null.Brian Anderson-11/+19
This allows blocks to be used in conditional constructs where the block may not ever execute: the drop glue will notice that it was never used and ignore it. Also, beef up the comments.
