fd52224e78 Remove dead code from librustc 2014-09-24 21:03:55 +02:00

78a841810e librustc: Implement associated types behind a feature gate. 
The implementation essentially desugars during type collection and AST
type conversion time into the parameter scheme we have now. Only fully
qualified names--e.g. `<T as Foo>::Bar`--are supported.

d8dfe1957b Align with _mut conventions 
As per [RFC
52](https://github.com/rust-lang/rfcs/blob/master/active/0052-ownership-variants.md),
use `_mut` suffixes to mark mutable variants, and `into_iter` for moving
iterators.

4459fe3e5e Revise VecPerParamSpace to use a one Vec rather than three. 
In my informal measurements, this brings the peak memory usage when
building librustc from 1662M down to 1502M.  Since 1662 - 1502 = 160,
this may not recover the entirety of the observed memory regression
(250M) from PR #14604.  (However, according to my local measurements,
the regression when building librustc was more like 209M, so perhaps
this will still recover the lions share of the lost memory.)

952dded81a Refactored VecPerParamSpace to hide exposure of Vec representation. 
This basically meant changing the interface so that no borrowed `&Vec`
is exposed, by hiding `fn get_vec` and `fn get_mut_vec` and revising
`fn all_vecs`.

Instead, clients should use one of the other methods; `get_slice`,
`pop`, `truncate`, `replace`, `push_all`, or `is_empty_in`, which
should work for any case currently used in rustc.

9153d8ad6c Introduce VecPerParamSpace and use it to represent sets of types and 
parameters

This involves numerous substeps:

1. Treat Self same as any other parameter.
2. No longer compute offsets for method parameters.
3. Store all generic types (both trait/impl and method) with a method,
   eliminating odd discrepancies.
4. Stop doing unspeakable things to static methods and instead just use
   the natural types, now that we can easily add the type parameters from
   trait into the method's polytype.
5. No doubt some more. It was hard to separate these into distinct commits.

Fixes #13564

7d6f1aa2ac Factor out foldable better to reduce code duplication. There is now a "double 
dispatch" pattern that lets you easily write new folders and then apply them to
various structures, reusing the "folding" effort.

ed7c849057 Currently trans uses Vec<ty::t> to represent substitutions instead of a proper 
ty::substs struct. This is a holdover from the olden days of yore. This patch
removes the last vestiges of that practice. This is part of the work
I was doing on #5527.
