3657ae13f5 Don't normalize associated types when in region binders, wait until we instantiate 
them. Also fix some assertions and handling of builtin bounds.

986f654f3b Rename trait_ref field to predicate, since trait_ref is really 
overly general, and the value is always *some* sort of predicate.

9f492fefef Switch to using predicates to drive checking. Correct various tests -- 
in most cases, just the error message changed, but in some cases we
are reporting new errors that OUGHT to have been reported before but
we're overlooked (mostly involving the `'static` bound on `Send`).

d85ff16173 Treat builtin bounds like all other kinds of trait matches. Introduce a simple hashset in the fulfillment context to catch cases where we register the exact same obligation twice. This helps prevent duplicate error reports but also handles the recursive obligations created by builtin bounds. 2014-12-02 19:05:14 -05:00

1da73ff126 Avoid O(n^2) performance by reconsidering the full set of obligations only when we are about to report an error (#18208). I found it is still important to consider the full set in order to make tests like let x: Vec<_> = obligations.iter().collect() work. 2014-10-28 08:18:21 -04:00

ce0907e46e Add enum variants to the type namespace 
Change to resolve and update compiler and libs for uses.

[breaking-change]

Enum variants are now in both the value and type namespaces. This means that
if you have a variant with the same name as a type in scope in a module, you
will get a name clash and thus an error. The solution is to either rename the
type or the variant.
