Deprecate `intrinsics::drop_in_place` and `collections::Bound`, which accidentally weren't deprecated Fixes #82080. I've taken the liberty of updating the `since` values to 1.52, since an unobservable deprecation isn't much of a deprecation (even the detailed release notes never bothered to mention these deprecations). As mentioned in the issue I'm *pretty* sure that using a type alias for `Bound` is semantically equivalent to the re-export; [the reference implies](https://doc.rust-lang.org/reference/items/type-aliases.html) that type aliases only observably differ from types when used on unit structs or tuple structs, whereas `Bound` is an enum.

fix the false 'defined here' messages Closes #80853. Take this code: ```rust struct S; fn repro_ref(thing: S) { thing(); } ``` Previously, the error message would be this: ``` error[E0618]: expected function, found `S` --> src/lib.rs:4:5 | 3 | fn repro_ref(thing: S) { | ----- `S` defined here 4 | thing(); | ^^^^^-- | | | call expression requires function error: aborting due to previous error ``` This is incorrect as `S` is not defined in the function arguments, `thing` is defined there. With this change, the following is emitted: ``` error[E0618]: expected function, found `S` --> $DIR/80853.rs:4:5 | LL | fn repro_ref(thing: S) { | ----- is of type `S` LL | thing(); | ^^^^^-- | | | call expression requires function | = note: local variable `S` is not a function error: aborting due to previous error ``` As you can see, this error message points out that `thing` is of type `S` and later in a note, that `S` is not a function. This change does seem like a downside for some error messages. Take this example: ``` LL | struct Empty2; | -------------- is of type `Empty2` ``` As you can see, the error message shows that the definition of `Empty2` is of type `Empty2`. Although this isn't wrong, it would be more helpful if it would say something like this (which was there previously): ``` LL | struct Empty2; | -------------- `Empty2` defined here ``` If there is a better way of doing this, where the `Empty2` example would stay the same as without this change, please inform me. **Update: This is now fixed** CC `@camelid`

2021-02-21Auto merge of #79100 - a1phyr:better_assert_eq, r=m-ou-sebors-4/+1
Improve assert_eq! and assert_ne! This PR improves `assert_eq!` and `assert_ne!` by moving the panicking code in an external function. It does not change the fast path, but the move of the formatting in the cold path (the panic) may have a positive effect on in instruction cache use and with inlining. Moreover, the use of trait objects instead of generic may improve compile times for `assert_eq!`-heavy code.

Suggest to create a new `const` item if the `fn` in the array is a `const fn` Fixes #73734. If the `fn` in the array repeat expression is a `const fn`, suggest creating a new `const` item. On nightly, suggest creating an inline `const` block. This PR also removes the `suggest_const_in_array_repeat_expressions` as it is no longer necessary. Example: ```rust fn main() { // Should not compile but hint to create a new const item (stable) or an inline const block (nightly) let strings: [String; 5] = [String::new(); 5]; println!("{:?}", strings); } ``` Gives this error: ``` error[E0277]: the trait bound `std::string::String: std::marker::Copy` is not satisfied --> $DIR/const-fn-in-vec.rs:3:32 | 2 | let strings: [String; 5] = [String::new(); 5]; | ^^^^^^^^^^^^^^^^^^ the trait `std::marker::Copy` is not implemented for `String` | = note: the `Copy` trait is required because the repeated element will be copied ``` With this change, this is the error message: ``` error[E0277]: the trait bound `String: Copy` is not satisfied --> $DIR/const-fn-in-vec.rs:3:32 | LL | let strings: [String; 5] = [String::new(); 5]; | ^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `String` | = help: moving the function call to a new `const` item will resolve the error ```

2021-02-08Rollup merge of #81779 - geogriff:const-ptr-to-int-error, r=lcnrMara Bos-9/+9
improve error message for disallowed ptr-to-int casts in const eval Improves an error message as [suggested](https://github.com/rust-lang/rust/issues/80875#issuecomment-762754580) in #80875. Does the wording make enough sense? I tried to follow precedent for error message style while maintaining brevity. It seems like the rest of the `ConstEvalErrKind::NeedsRfc` error messages could be improved as well. I could give that a go if this approach works. Closes #80875
2021-02-08Auto merge of #80962 - jhpratt:const_int_fn-stabilization, r=dtolnaybors-5/+0
Stabilize remaining integer methods as `const fn` This pull request stabilizes the following methods as `const fn`: - `i*::checked_div` - `i*::checked_div_euclid` - `i*::checked_rem` - `i*::checked_rem_euclid` - `i*::div_euclid` - `i*::overflowing_div` - `i*::overflowing_div_euclid` - `i*::overflowing_rem` - `i*::overflowing_rem_euclid` - `i*::rem_euclid` - `i*::wrapping_div` - `i*::wrapping_div_euclid` - `i*::wrapping_rem` - `i*::wrapping_rem_euclid` - `u*::checked_div` - `u*::checked_div_euclid` - `u*::checked_rem` - `u*::checked_rem_euclid` - `u*::div_euclid` - `u*::overflowing_div` - `u*::overflowing_div_euclid` - `u*::overflowing_rem` - `u*::overflowing_rem_euclid` - `u*::rem_euclid` - `u*::wrapping_div` - `u*::wrapping_div_euclid` - `u*::wrapping_rem` - `u*::wrapping_rem_euclid` These can all be implemented on the current stable (1.49). There are two unstable details: const likely/unlikely and unchecked division/remainder. Both of these are for optimizations, and are in no way required to make the methods function; there is no exposure of these details publicly. Per comments below, it seems best practice is to stabilize the intrinsics. As such, `intrinsics::unchecked_div` and `intrinsics::unchecked_rem` have been stabilized as `const` as part of this pull request as well. The methods themselves remain unstable. I believe part of the reason these were not stabilized previously was the behavior around division by 0 and modulo 0. After testing on nightly, the diagnostic for something like `const _: i8 = 5i8 % 0i8;` is similar to that of `const _: i8 = 5i8.rem_euclid(0i8);` (assuming the appropriate feature flag is enabled). As such, I believe these methods are ready to be stabilized as `const fn`. This pull request represents the final methods mentioned in #53718. As such, this PR closes #53718. `@rustbot` modify labels to +A-const-fn, +T-libs
2021-02-07Auto merge of #80652 - calebzulawski:simd-lanes, r=nagisabors-3/+7
Improve SIMD type element count validation Resolves rust-lang/stdsimd#53. These changes are motivated by `stdsimd` moving in the direction of const generic vectors, e.g.: ```rust #[repr(simd)] struct SimdF32<const N: usize>([f32; N]); ``` This makes a few changes: * Establishes a maximum SIMD lane count of 2^16 (65536). This value is arbitrary, but attempts to validate lane count before hitting potential errors in the backend. It's not clear what LLVM's maximum lane count is, but cranelift's appears to be much less than `usize::MAX`, at least. * Expands some SIMD intrinsics to support arbitrary lane counts. This resolves the ICE in the linked issue. * Attempts to catch invalid-sized vectors during typeck when possible. Unresolved questions: * Generic-length vectors can't be validated in typeck and are only validated after monomorphization while computing layout. This "works", but the errors simply bail out with no context beyond the name of the type. Should these errors instead return `LayoutError` or otherwise provide context in some way? As it stands, users of `stdsimd` could trivially produce monomorphization errors by making zero-length vectors. cc `@bjorn3`

It is a lot easier to parse fixed sized rows.
2021-02-01Auto merge of #80851 - m-ou-se:panic-2021, r=petrochenkovbors-16/+18
Implement Rust 2021 panic This implements the Rust 2021 versions of `panic!()`. See https://github.com/rust-lang/rust/issues/80162 and https://github.com/rust-lang/rfcs/pull/3007. It does so by replacing `{std, core}::panic!()` by a bulitin macro that expands to either `$crate::panic::panic_2015!(..)` or `$crate::panic::panic_2021!(..)` depending on the edition of the caller. This does not yet make std's panic an alias for core's panic on Rust 2021 as the RFC proposes. That will be a separate change: https://github.com/rust-lang/rust/pull/80879/commits/c5273bdfb266c35e8eab9413aa8d58d27fdbe114 That change is blocked on figuring out what to do with https://github.com/rust-lang/rust/issues/80846 first.

Remove const_in_array_repeat Fixes #80371. Fixes #81315. Fixes #80767. Fixes #75682. I thought there might be some issue with `Repeats(_, 0)`, but if you increase the items in the array it still ICEs. I'm not sure if this is the best fix but it does fix the given issue.

2021-01-30Rollup merge of #80886 - RalfJung:stable-raw-ref-macros, r=m-ou-seYuki Okushi-14/+12
Stabilize raw ref macros This stabilizes `raw_ref_macros` (https://github.com/rust-lang/rust/issues/73394), which is possible now that https://github.com/rust-lang/rust/issues/74355 is fixed. However, as I already said in https://github.com/rust-lang/rust/issues/73394#issuecomment-751342185, I am not particularly happy with the current names of the macros. So I propose we also change them, which means I am proposing to stabilize the following in `core::ptr`: ```rust pub macro const_addr_of($e:expr) { &raw const $e } pub macro mut_addr_of($e:expr) { &raw mut $e } ``` The macro name change means we need another round of FCP.
