21fb49ad95 Join the results of alt arms so alt can be used as an expression. 
Un-XFAIL expr-alt.rs.

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.

9d0a505d61 Terminate fail blocks by making their ends unreachable. 
This will make implementing default alt arms simpler.

ec9d7abf8c rustc: Have tag_variants() return a new variant_info structure instead of an AST node 2011-04-01 11:37:31 -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.

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.

933c01bd15 Every upcall needs a task pointer to find the C stack. It is just that when

that are defined after use in a block.

This is really inefficient, but for now it lets us compile the included test.
