Reword E0392 slightly Make it clearer that a type or lifetime argument not being used can be fixed by referencing it in a struct's fields, not just using `PhathomData`. CC #53589.

2019-09-23Rollup merge of #64679 - skinny121:const-infer, r=varkorMazdak Farrokhzad-0/+29
Infer consts more consistently Moved some duplicated logic in `TypeRelation` methods into `super_combined_consts`. Before some `TypeRelation`s like `Lub` wasn't using `replace_if_possible`, meaning some inference types were staying around longer than they should be. Fixes https://github.com/rust-lang/rust/issues/64519 r? @varkor

2019-07-07rustc/rustc_mir: Implement RFC 2203.David Wood-16/+22
This commit implements RFC 2203, allowing constants in array repeat expressions. Firstly, the check that the array repeat expression implements `Copy` is removed and re-implemented in `rustc_mir::borrow_check::nll::type_check` by emitting an error when the MIR contains a `Operand::Move` and the type does not implement `Copy`. Next, the `qualify_consts` pass is modified to construct a `Candidate::Repeat` when it would be correct to promote a array repeat expression. Finally, the `promote_consts` pass is modified to promote the candidates previously identified.
2019-07-07Use const generics for array impls, restricted to 0..=32Scott McMurray-8/+158
- uses a never-stable core::array::LengthAtMost32 to bound the impls - includes a custom error message to avoid mentioning LengthAtMost32 too often - doesn't use macros for the slice implementations to avoid #62433

2019-06-13typeck: Fix ICE for blocks in repeat expr count.David Wood-0/+34
This commit extends the work in #61698 to get the `DefId` of const parameters from block that resolve to a const parameter (as well as const parameters directly, as it was previously).
2019-06-11Rollup merge of #61698 - davidtwco:ice-const-generic-length, r=varkorMazdak Farrokhzad-0/+60
typeck: Fix const generic in repeat param ICE. Fixes #61336. Turns out this wasn't related to #49147 after all. r? @varkor
2019-06-10typeck: Fix const generic in repeat param ICE.David Wood-0/+60
This commit fixes an ICE that occured when a const generic was used in a repeat expression. This was due to the code expecting the length of the repeat expression to be const evaluatable to a constant, but a const generic parameter is not (however, it can be made into a constant).
