r=petrochenkov Compiler error messages: reduce assertiveness of message E0384 This message is emitted as guidance by the compiler when a developer attempts to reassign a value to an immutable variable. Following the message will always currently work, but it may not always be the best course of action; following the 'consider ...' messaging pattern provides a hint to the developer that it could be wise to explore other alternatives. Resolves #84144

2021-04-16Rollup merge of #83337 - Manishearth:item-hide, r=GuillaumeGomezDylan DPC-154/+347
rustdoc: Hide item contents, not items This tweaks rustdoc to hide item contents instead of items, and only when there are too many of them. This means that users will _always_ see the type parameters, and will _often_ see fields/etc as long as they are small. Traits have some heuristics for hiding only the methods or only the methods and the consts, since the associated types are super important. I'm happy to play around with the heuristics here; we could potentially make it so that structs/enums/etc are always hidden but traits will try really hard to show type aliases. This needs a test, but you can see it rendered at https://manishearth.net/sand/doc_render/bar/ <details> <summary> Code example </summary> ```rust pub struct PubStruct { pub a: usize, pub b: usize, } pub struct BigPubStruct { pub a: usize, pub b: usize, pub c: usize, pub d: usize, pub e: usize, pub f: usize, } pub union BigUnion { pub a: usize, pub b: usize, pub c: usize, pub d: usize, pub e: usize, pub f: usize, } pub union Union { pub a: usize, pub b: usize, pub c: usize, } pub struct PrivStruct { a: usize, b: usize, } pub enum Enum { A, B, C, D { a: u8, b: u8 } } pub enum LargeEnum { A, B, C, D, E, F, G, H, I, J } pub trait Trait { type A; #[must_use] fn foo(); fn bar(); } pub trait GinormousTrait { type A; type B; type C; type D; type E; type F; const N: usize = 1; #[must_use] fn foo(); fn bar(); } pub trait HugeTrait { type A; const M: usize = 1; const N: usize = 1; const O: usize = 1; const P: usize = 1; const Q: usize = 1; #[must_use] fn foo(); fn bar(); } pub trait BigTrait { type A; #[must_use] fn foo(); fn bar(); fn baz(); fn quux(); fn frob(); fn greeble(); } #[macro_export] macro_rules! foo { (a) => {a}; } ``` </details> Fixes https://github.com/rust-lang/rust/issues/82114

2021-04-16Auto merge of #84217 - crlf0710:remove_main_attr_pure, r=petrochenkovbors-185/+37
Remove #[main] attribute. This removes the #[main] attribute support from the compiler according to the decisions within #29634. For existing use cases within test harness generation, replaced it with a newly-introduced internal attribute `#[rustc_main]`. This is first part extracted from #84062 . Closes #29634. r? `@petrochenkov`

Add simd_{round,trunc} intrinsics LLVM supports many functions from math.h in its IR. Many of these have SIMD instructions on various platforms. So, let's add round and trunc so std::arch can use them. Yes, exact comparison is intentional: rounding must always return a valid integer-equal value, except for inf/NAN.

Fix typo in error message Also tweaked the message a bit by - removing the hyphen, because in my opinion the hyphen makes the message a bit harder to read, especially combined with the backticks; - adding the word "be", because I think it's a bit clearer that way.
