86d4601827 More work on typestate. Sketched out code for computing and checking prestates and poststates. Still a long ways away. 2011-04-06 00:17:06 +00:00

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!).

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()

21fb49ad95 Join the results of alt arms so alt can be used as an expression.

203e33b611 Make join_results branch into the join block even when only one edge is live.
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.

This will make implementing default alt arms simpler.

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.

f16e7242d2 Initialize the alloca used to retrieve boxed block results to null.
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.

b0b72ab472 Restore scope block contexts to the translation of expr_block.
I removed this previously but that was wrong because it caused
block expressions to not create a new scope.
