2018-05-16Auto merge of #48557 - matthewjasper:allow-trvial-bounds, r=nikomatsakisbors-65/+1084
Implement RFC 2056 trivial constraints in where clauses This is an implementation of the new behaviour for #48214. Tests are mostly updated to show the effects of this. Feature gate hasn't been added yet. Some things that are worth noting and are maybe not want we want * `&mut T: Copy` doesn't allow as much as someone might expect because there is often an implicit reborrow. * ~There isn't a check that a where clause is well-formed any more, so `where Vec<str>: Debug` is now allowed (without a `str: Sized` bound).~ r? @nikomatsakis

2018-05-16Auto merge of #50750 - est31:master, r=eddybbors-127/+48
Remove ScopeTarget and LoopIdResult * Remove ScopeTarget in preparation of label-break-value (PR #50045) * Replace LoopIdResult by Result which is possible now thanks to commit 8ac65af81f5f9cf6c5e2c2306705b50eed77cfb5 " Implement Encodable and Decodable for Result." r? @eddyb

2018-05-16Auto merge of #50541 - QuietMisdreavus:rustdoc-errors, r=GuillaumeGomezbors-122/+144
rustdoc: replace most (e)println! statements with structured warnings/errors Turns out, the rustc diagnostic handler doesn't need a whole lot of setup that we weren't already doing. For errors that occur outside a "dealing with source code" context, we can just use the format/color config we were already parsing and make up a `Handler` that we can emit structured warnings/errors from. So i did that. This will make it way easier to test things with `rustdoc-ui` tests, since those require the JSON error output. (In fact, this PR is a yak shave for a different one where i was trying to do just that. `>_>`)
2018-05-15Auto merge of #48523 - varkor:generics-ty-generalisations, r=nikomatsakisbors-806/+966
The Great Generics Generalisation: Ty Edition Part of the generic parameter refactoring effort, split off from https://github.com/rust-lang/rust/pull/48149. Contains the `ty`-relative refactoring. r? @eddyb

2018-05-15Auto merge of #50767 - oli-obk:rls_clippy, r=kennytmbors-9/+0
Don't inject clippy into the rls anymore r? @kennytm sorry about breaking nightlies. The issue is that the `[patch.crates-io]` doesn't work if the versions differ. So every time we update clippy, we can only update it to the verison that rls is depending on. I'm disabling the injection of clippy into rls for now. I'm not sure how to do this properly. We could * add a version check, so rls only builds clippy if its dependency clippy is the same as the submodule clippy * do something crazy like auto-patching the Cargo.toml of the rls tool repo to just use a path dependency on clippy * build crates-io clippy instead of submodule clippy and gate clippy injection on that * that's somewhat automatic, and is essentially what is necessary right now, but done manually * make clippy 0.1.* instead of 0.0.* and update patch versions for nightly updates and minor version updates for `clippy_lints` api changes. * not sure how semver-great this is

2018-05-15Pattern match on Ok instead of Some of .ok() retvalest31-1/+1
2018-05-15Remove LoopIdResultest31-64/+19
It's redundant as Result already implements Encodable as well as Decodable.
2018-05-15Remove hir::ScopeTargetest31-85/+51
When we want to implement label-break-value, we can't really decide whether to emit ScopeTarget::Loop or ScopeTarget::Block in the code that is supposed to create it. So we get rid of it and reconstruct the information when needed.

2018-05-15Pull common parameters into GenericParamDefvarkor-266/+263
This leads to a lot of simplifications, as most code doesn't actually need to know about the specific lifetime/type data; rather, it's concerned with properties like name, index and def_id.
