2021-04-17Rollup merge of #84150 - jsha:defer-search-js, r=GuillaumeGomezDylan DPC-1693/+1682
rustdoc: move some search code into search.js This reduces main.s from 3094 lines to 1587. Also it saves some bytes of download in the case where search isn't used. There were a fair number of variables that needed to be accessible in both main.js and search.js, but I didn't want to put too many symbols in the global namespace, so I consolidated much of the search-related state and functions into a new object `window.searchState`. Demo at https://hoffman-andrews.com/rust/move-search/std/?search=foo
2021-04-17Rollup merge of #83237 - notriddle:short-links, r=jyn514Dylan DPC-547/+576
rustdoc: use more precise relative URLs This is a fairly large diff, and will probably conflict with https://github.com/rust-lang/rust/pull/82815 since it reduces (but does not eliminate) the use of the old depth variable. Instead of using a depth counter and adding "../" to get to the top, this commit makes rustdoc actually compare the path of what it's linking from to the path that it's linking to. This makes the resulting HTML shorter. Here's a comparison of one of the largest (non-source) files in the Rust standard library docs (about 4% improvement before gzipping). $ wc -c struct.Wrapping.old.html struct.Wrapping.new.html 2387389 struct.Wrapping.old.html 2298538 struct.Wrapping.new.html Most if it can be efficiently gzipped away. $ wc -c struct.Wrapping.old.html.gz struct.Wrapping.new.html.gz 70679 struct.Wrapping.old.html.gz 70050 struct.Wrapping.new.html.gz But it also makes a difference in the final DOM size, reducing it from 91MiB to 82MiB.

Builtin derive macros: fix error with const generics default This fixes a bug where builtin derive macros (like Clone, Debug) would basically copy-paste the default from a const generic, causing a compile error with very confusing message - it would say defaults are not allowed in impl blocks, while pointing at struct/enum/union definition.
2021-04-17Auto merge of #84113 - SNCPlay42:suggestion-extern-crate, r=petrochenkovbors-0/+39
Detect when suggested paths enter extern crates more rigorously When reporting resolution errors, the compiler tries to avoid suggesting importing inaccessible paths from other crates. However, the search for suggestions only recognized when it was entering a crate root directly, and so failed to recognize a path like `crate::module::private_item`, where `module` was imported from another crate with `use other_crate::module`, as entering another crate. Fixes #80079 Fixes #84081

2021-04-16Auto merge of #83416 - alexcrichton:const-thread-local, r=sfacklerbors-0/+17
std: Add a variant of thread locals with const init This commit adds a variant of the `thread_local!` macro as a new `thread_local_const_init!` macro which requires that the initialization expression is constant (e.g. could be stuck into a `const` if so desired). This form of thread local allows for a more efficient implementation of `LocalKey::with` both if the value has a destructor and if it doesn't. If the value doesn't have a destructor then `with` should desugar to exactly as-if you use `#[thread_local]` given sufficient inlining. The purpose of this new form of thread locals is to precisely be equivalent to `#[thread_local]` on platforms where possible for values which fit the bill (those without destructors). This should help close the gap in performance between `thread_local!`, which is safe, relative to `#[thread_local]`, which is not easy to use in a portable fashion.

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.

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

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.
