2011-04-09Move to single-uint file-position representation.Marijn Haverbeke-2/+3
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.

2011-04-08Implemented computing prestates and poststates for a few expression forms.Tim Chevalier-63/+224
The typestate checker (if it's uncommented) now correctly rejects a trivial example program that has an uninitialized variable.
2011-04-07Make block results work for generic typesBrian Anderson-14/+17
I think just about every type can be used as a block result now. There's quite a proliferation of tests here, but they all test slightly different things and some are split out to remain XFAILed. The tests of generic vectors are still XFAILed because generic aliased boxes still don't work in general.

2011-04-07Support for self-calls that take arguments.Lindsey Kuper-33/+58
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).
2011-04-07Fix problem in metadata writerMarijn Haverbeke-0/+4
It was creating non-multiple-of-four section sizes, which, for some reason, presumably by LLVM, were clipped, rather than padded, to be a multiple of four.

2011-04-07Run optimizations.Rafael Ávila de Espíndola-5/+66
It is always on for now just to make sure the bots are happy. If they are, I will add a -O option and update the makefile.
2011-04-06Continued sketching out code for checking states against preconditions.Tim Chevalier-115/+215
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.

2011-04-06More work on typestate. Sketched out code for computing and checking ↵Tim Chevalier-75/+482
prestates and poststates. Still a long ways away.
2011-04-05Last pieces of self-call support.Lindsey Kuper-5/+36
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-114/+87
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
2011-04-05Knocking out a quick fixme: pretty-printing exprs in error messages.Lindsey Kuper-2/+3
2011-04-04Make box prefix operator and box type carry mutability flag.Graydon Hoare-11/+10
2011-04-03rustc: Make type_of() return the type of the wrapper for native functions. ↵Patrick Walton-4/+4
lib-map now compiles, but fails to work properly.
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-0/+2
Major perf win.
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-12/+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.

2011-04-01Started adding support for typestate checking.Tim Chevalier-197/+685
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.
