2019-02-22Switch from error patterns to `//~ ERROR` markers.Felix S. Klock II-8/+11
AFAICT, we do not have the same const-eval issues that we used to when rust-lang/rust#23926 was filed. (Probably because of the switch to miri for const-evaluation.)

Fix evaluating trivial drop glue in constants ```rust struct A; impl Drop for A { fn drop(&mut self) {} } const FOO: Option<A> = None; const BAR: () = (FOO, ()).1; ``` was erroring with ``` error: any use of this value will cause an error --> src/lib.rs:9:1 | 9 | const BAR: () = (FOO, ()).1; | ^^^^^^^^^^^^^^^^^^^^^^^^^^-^ | | | calling non-const function `std::ptr::real_drop_in_place::<(std::option::Option<A>, ())> - shim(Some((std::option::Option<A>, ())))` | = note: #[deny(const_err)] on by default error: aborting due to previous error ``` before this PR.

Remove unnecessary dummy span checks The emitter already verifies wether a given span note or span label can be emitted to the output. If it can't, because it is a dummy span, it will be either elided for labels or emitted as an unspanned note/help when applicable.

2019-01-12Rollup merge of #57175 - oli-obk:const_let_stabilization, r=nikomatsakisMazdak Farrokhzad-360/+152
Stabilize `let` bindings and destructuring in constants and const fn r? @Centril This PR stabilizes the following features in constants and `const` functions: * irrefutable destructuring patterns (e.g. `const fn foo((x, y): (u8, u8)) { ... }`) * `let` bindings (e.g. `let x = 1;`) * mutable `let` bindings (e.g. `let mut x = 1;`) * assignment (e.g. `x = y`) and assignment operator (e.g. `x += y`) expressions, even where the assignment target is a projection (e.g. a struct field or index operation like `x[3] = 42`) * expression statements (e.g. `3;`) This PR does explicitly *not* stabilize: * mutable references (i.e. `&mut T`) * dereferencing mutable references * refutable patterns (e.g. `Some(x)`) * operations on `UnsafeCell` types (as that would need raw pointers and mutable references and such, not because it is explicitly forbidden. We can't explicitly forbid it as such values are OK as long as they aren't mutated.) * We are not stabilizing `let` bindings in constants that use `&&` and `||` short circuiting operations. These are treated as `&` and `|` inside `const` and `static` items right now. If we stopped treating them as `&` and `|` after stabilizing `let` bindings, we'd break code like `let mut x = false; false && { x = true; false };`. So to use `let` bindings in constants you need to change `&&` and `||` to `&` and `|` respectively.

Const-stabilize `const_int_ops` + `const_ip` r? @oli-obk ## Note for relnotes: This PR includes https://github.com/rust-lang/rust/pull/57105. I've added T-lang since this affects intrinsics and the operational semantics of Rust's `const fn` fragment. ## Stable APIs proposed for constification + `const_int_ops`: + `count_ones` + `count_zeros` + `leading_zeros` + `trailing_zeros` + `swap_bytes` + `from_be` + `from_le` + `to_be` + `to_le` + `const_ip` + `Ipv4Addr::new` ## Unstable APIs constified + `const_int_conversion`: + `reverse_bits`
