f3ff084d01 Remove the regionck impl of Typer and just use fcx. This requires 
modifying fcx to remove type variables where possible, but that's it.

14597f980a auto merge of #19813 : barosl/rust/autoderef-type-inference-ice, r=pnkfelix 
`check::autoderef()` returns a `ty_err` when it fails to infer the type. `probe::probe()` should respect this failure and fail together to prevent further corruption.

Fixes #19692.
Fixes #19583.

Chis Morgan has a pretty important documentation fix in #19385 and he hasn't responded in a while to that pull request so I rebased it for him

b3dcb85404 Fix a bug in the opt-in-copy work: it was failing to liberate the regions bound in the impl before searching for Copy implements for all fields, leading to problems in the "copyability check". Basically the copyability check would wind up looking for an impl of for<'tcx> Foo<&'tcx T>. The impl that exists however is impl<T> Copy for Foo<T> and the current rules do not consider that a match (something I would like to revise in a later PR). 2014-12-19 03:29:30 -05:00

ddb2466f6a librustc: Always parse macro!()/macro![] as expressions if not 
followed by a semicolon.

This allows code like `vec![1i, 2, 3].len();` to work.

This breaks code that uses macros as statements without putting
semicolons after them, such as:

    fn main() {
        ...
        assert!(a == b)
        assert!(c == d)
        println(...);
    }

It also breaks code that uses macros as items without semicolons:

    local_data_key!(foo)

    fn main() {
        println("hello world")
    }

Add semicolons to fix this code. Those two examples can be fixed as
follows:

    fn main() {
        ...
        assert!(a == b);
        assert!(c == d);
        println(...);
    }

    local_data_key!(foo);

    fn main() {
        println("hello world")
    }

RFC #378.

Closes #18635.

Part of #18469

[breaking-change]

A receiver will only ever get a single auto-reference. Previously arrays and strings would get two, e.g., [T] would be auto-ref'ed to &&[T]. This is usually apparent when a trait is implemented for `&[T]` and has a method takes self by reference. The usual solution is to implement the trait for `[T]` (the DST form).
