2020-07-15improve DiscriminantKind handlingBastian Kauschke-0/+1
This now reuses `fn discriminant_ty` in project, removing some code duplication. Doing so made me realize that we previously had a disagreement about the discriminant type of generators, with MIR using `u32` and codegen and trait selection using `i32`. We now always use `u32`.

2020-04-26Use min_specialization in liballocMatthew Jasper-0/+7
- Remove a type parameter from `[A]RcFromIter`. - Remove an implementation of `[A]RcFromIter` that didn't actually specialize anything. - Remove unused implementation of `IsZero` for `Option<&mut T>`. - Change specializations of `[A]RcEqIdent` to use a marker trait version of `Eq`. - Remove `BTreeClone`. I couldn't find a way to make this work with `min_specialization`. - Add `rustc_unsafe_specialization_marker` to `Copy` and `TrustedLen`.

2019-10-25Migrate from `#[structural_match]` attribute a lang-item trait.Felix S. Klock II-0/+87
(Or more precisely, a pair of such traits: one for `derive(PartialEq)` and one for `derive(Eq)`.) ((The addition of the second marker trait, `StructuralEq`, is largely a hack to work-around `fn (&T)` not implementing `PartialEq` and `Eq`; see also issue rust-lang/rust#46989; otherwise I would just check if `Eq` is implemented.)) Note: this does not use trait fulfillment error-reporting machinery; it just uses the trait system to determine if the ADT was tagged or not. (Nonetheless, I have kept an `on_unimplemented` message on the new trait for structural_match check, even though it is currently not used.) Note also: this does *not* resolve the ICE from rust-lang/rust#65466, as noted in a comment added in this commit. Further work is necessary to resolve that and other problems with the structural match checking, especially to do so without breaking stable code (adapted from test fn-ptr-is-structurally-matchable.rs): ```rust fn r_sm_to(_: &SM) {} fn main() { const CFN6: Wrap<fn(&SM)> = Wrap(r_sm_to); let input: Wrap<fn(&SM)> = Wrap(r_sm_to); match Wrap(input) { Wrap(CFN6) => {} Wrap(_) => {} }; } ``` where we would hit a problem with the strategy of unconditionally checking for `PartialEq` because the type `for <'a> fn(&'a SM)` does not currently even *implement* `PartialEq`. ---- added review feedback: * use an or-pattern * eschew `return` when tail position will do. * don't need fresh_expansion; just add `structural_match` to appropriate `allow_internal_unstable` attributes. also fixed example in doc comment so that it actually compiles.

2019-09-23Move `--cfg bootstrap` out of `rustc.rs`Alex Crichton-1/+1
Instead let's do this via `RUSTFLAGS` in `builder.rs`. Currently requires a submodule update of `stdarch` to fix a problem with previous compilers.
