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.

a47cd50dfb Parse FP literals without coercing to int. This allows parsing 64-bit
floats. However, if someone writes a literal that can't be represented
precisely in 64 bits, the front-end will accept it while the back-end
will (presumably) complain.
