Improve lint for type alias bounds

First of all, I learned just today that I was wrong assuming that the bounds in type aliases are entirely ignored: It turns out they are used to resolve associated types in type aliases. So:
```rust
type T1<U: Bound> = U::Assoc; // compiles
type T2<U> = U::Assoc; // fails
type T3<U> = <U as Bound>::Assoc; // "correct" way to write this, maybe?
```
I am sorry for creating this mess.

This PR changes the wording of the lint accordingly. Moreover, since just removing the bound is no longer always a possible fix, I tried to detect cases like `T1` above and show a helpful message to the user:
```
warning: bounds on generic parameters are not enforced in type aliases
  --> $DIR/type-alias-bounds.rs:57:12
   |
LL | type T1<U: Bound> = U::Assoc; //~ WARN not enforced in type aliases
   |            ^^^^^
   |
   = help: the bound will not be checked when the type alias is used, and should be removed
help: use absolute paths (i.e., <T as Trait>::Assoc) to refer to associated types in type aliases

   |
LL | type T1<U: Bound> = U::Assoc; //~ WARN not enforced in type aliases
   |                     ^^^^^^^^
```
I am not sure if I got this entirely right. Ideally, we could provide a suggestion involving the correct trait and type name -- however, while I have access to the HIR in the lint, I do not know how to get access to the resolved name information, like which trait `Assoc` belongs to above. The lint does not even run if that resolution fails, so I assume that information is available *somewhere*...

This is a follow-up for (parts of) https://github.com/rust-lang/rust/pull/48326. Also see https://github.com/rust-lang/rust/issues/21903.

This changes the name of a lint, but that lint was just merged to master yesterday and has never even been on beta.

rustc: Add a `#[wasm_custom_section]` attribute

This commit is an implementation of adding custom sections to wasm artifacts in
rustc. The intention here is to expose the ability of the wasm binary format to

The implementation here is to attach a `#[wasm_custom_section = "foo"]`
attribute to any `const` which has a type like `[u8; N]`. Other types of
constants aren't supported yet but may be added one day! This should hopefully
be enough to get off the ground with *some* custom section support.

The current semantics are that any constant tagged with `#[wasm_custom_section]`
section will be *appended* to the corresponding section in the final output wasm

6 years agorustc: Add a `#[wasm_import_module]` attribute
Alex Crichton [Sat, 10 Feb 2018 22:28:17 +0000 (14:28 -0800)]
rustc: Add a `#[wasm_import_module]` attribute

This commit adds a new attribute to the Rust compiler specific to the wasm
target (and no other targets). The `#[wasm_import_module]` attribute is used to
specify the module that a name is imported from, and is used like so:

    #[wasm_import_module = "./foo.js"]
    extern {
        fn some_js_function();
    }

Here the import of the symbol `some_js_function` is tagged with the `./foo.js`
module in the wasm output file. Wasm-the-format includes two fields on all
imports, a module and a field. The field is the symbol name (`some_js_function`
above) and the module has historically unconditionally been `"env"`. I'm not
sure if this `"env"` convention has asm.js or LLVM roots, but regardless we'd
like the ability to configure it!

The proposed ES module integration with wasm (aka a wasm module is "just another
ES module") requires that the import module of wasm imports is interpreted as an
ES module import, meaning that you'll need to encode paths, NPM packages, etc.
As a result, we'll need this to be something other than `"env"`!

Unfortunately neither our version of LLVM nor LLD supports custom import modules
(aka anything not `"env"`). My hope is that by the time LLVM 7 is released both
will have support, but in the meantime this commit adds some primitive
encoding/decoding of wasm files to the compiler. This way rustc postprocesses
the wasm module that LLVM emits to ensure it's got all the imports we'd like to
have in it.

Eventually I'd ideally like to unconditionally require this attribute to be
placed on all `extern { ... }` blocks. For now though it seemed prudent to add
it as an unstable attribute, so for now it's not required (as that'd force usage
of a feature gate). Hopefully it doesn't take too long to "stabilize" this!

Auto merge of #48516 - petrochenkov:stabsl, r=nikomatsakis

Stabilize slice patterns without `..`

And merge `feature(advanced_slice_patterns)` into `feature(slice_patterns)`.

The detailed description can be found in https://github.com/rust-lang/rust/issues/48836.

Slice patterns were unstable for long time since before 1.0 due to many bugs in the implementation, now this stabilization is possible primarily due to work of @arielb1 who [wrote the new MIR-based implementation of slice patterns](https://github.com/rust-lang/rust/pull/32202) and @mikhail-m1 who [fixed one remaining class of codegen issues](https://github.com/rust-lang/rust/pull/47926).

Fix ordering of auto-generated trait bounds in rustdoc output

While the order of the where clauses was deterministic, the
ordering of bounds and lifetimes was not. This made the order flip-
flop randomly when new traits and impls were added to libstd.

This PR makes the ordering of bounds and lifetimes deterministic,
and re-enables the test that was causing the issue.

Add BufReader::buffer

This subsumes the need for an explicit is_empty function, and provides
access to the buffered data itself which has been requested from time to
time.

We could call this `buf` to match `fill_buf`, but I think I'd prefer `fill_buffer` anyways in hindsight.
