f26266e03d rustc: Refactor codemap::emit_* functions 
A codemap is only needed when we have a span so put them both into the option.

efb9df1ebd Make driver::session::session no longer an object 
Rather, it is now a struct where properties like opts are accessed
directly, and the error-reporting methods are part of a static impl
(with the same name as the type).

34d7f05292 Major clean-up of std::io 
Use ifaces instead of objs, stop wrapping everything in two (or three)
layers of no-value-added indirection, and remove some of the more
pointless/outdated idioms from the code.

0e334c6839 Fold and re-evaluate expr in tag discriminant. 2012-01-10 15:59:57 -08:00
Kevin Atkinson
08abf8d37f Support explicit discriminant numbers on tag variants. 
Addresses issue #1393.

For now disallow disr. values unless all variants use nullary
contractors (i.e. "enum-like").

Disr. values are now encoded in the crate metadata, but only when it
will differ from the inferred value based on the order.

506a6ec38b Make syntax for impls less magical 
The trick of interpreting parameters to the iface type as parameters
to the impl was just too magical.
