2020-03-15Rollup merge of #69471 - nnethercote:rm-sip-Hasher-short_write, r=dtolnayDylan DPC-46/+7
Remove `sip::Hasher::short_write`. `sip::Hasher::short_write` is currently unused. It is called by `sip::Hasher::write_{u8,usize}`, but those methods are also unused, because `DefaultHasher`, `SipHasher` and `SipHasher13` don't implement any of the `write_xyz` methods, so all their write operations end up calling `sip::Hasher::write`. (I confirmed this by inserting a `panic!` in `sip::Hasher::short_write` and running the tests -- they all passed.) The alternative would be to add all the missing `write_xyz` methods. This does give some significant speed-ups, but it hurts compile times a little in some cases. See #69152 for details. This commit does the conservative thing and doesn't change existing behaviour. r? @rust-lang/libs

2020-02-21Revert `u8to64_le` changes from #68914.Nicholas Nethercote-1/+3
`SipHasher128`'s `u8to64_le` function was simplified in #68914. Unfortunately, the new version is slower, because it introduces `memcpy` calls with non-statically-known lengths. This commit reverts the change, and adds an explanatory comment (which is also added to `libcore/hash/sip.rs`). This barely affects `SipHasher128`'s speed because it doesn't use `u8to64_le` much, but it does result in `SipHasher128` once again being consistent with `libcore/hash/sip.rs`.

2019-11-26Format libcore with rustfmtDavid Tolnay-60/+69
This commit applies rustfmt with default settings to files in src/libcore *that are not involved in any currently open PR* to minimize merge conflicts. The list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in `outstanding_files`, the relevant commands were: $ find src/libcore -name '*.rs' | xargs rustfmt --edition=2018 $ rg libcore outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libcore.

Instead let's do this via `RUSTFLAGS` in `builder.rs`. Currently requires a submodule update of `stdarch` to fix a problem with previous compilers.

2019-06-23Fix meta-variable binding errors in macrosJulien Cretin-3/+3
The errors are either: - The meta-variable used in the right-hand side is not bound (or defined) in the left-hand side. - The meta-variable used in the right-hand side does not repeat with the same kleene operator as its binder in the left-hand side. Either it does not repeat enough, or it uses a different operator somewhere. This change should have no semantic impact.

2018-03-17Mark deprecated unstable SipHasher13 as a doc-hidden impl detail of HashMap.Simon Sapin-6/+8
It stays in libcore rather than being private in HashMap’s module because it shares code with the deprecated *stable* `SipHasher` type.

It is still used by the deprecated *stable* `SipHasher` type.

2017-07-20std: Cut down #[inline] annotations where not necessaryAlex Crichton-1/+1
This PR cuts down on a large number of `#[inline(always)]` and `#[inline]` annotations in libcore for various core functions. The `#[inline(always)]` annotation is almost never needed and is detrimental to debug build times as it forces LLVM to perform inlining when it otherwise wouldn't need to in debug builds. Additionally `#[inline]` is an unnecessary annoation on almost all generic functions because the function will already be monomorphized into other codegen units and otherwise rarely needs the extra "help" from us to tell LLVM to inline something. Overall this PR cut the compile time of a [microbenchmark][1] by 30% from 1s to 0.7s. [1]: https://gist.github.com/alexcrichton/a7d70319a45aa60cf36a6a7bf540dd3a

2017-06-16Introduce tidy lint to check for inconsistent tracking issuesest31-1/+1
This commit * Refactors the collect_lib_features function to work in a non-checking mode (no bad pointer needed, and list of lang features). * Introduces checking whether unstable/stable tags for a given feature have inconsistent tracking issues. * Fixes such inconsistencies throughout the codebase.
2017-05-02Removal pass for anonymous parametersest31-2/+2
Removes occurences of anonymous parameters from the rustc codebase, as they are to be deprecated. See issue #41686 and RFC 1685.

2017-04-06improved std::hash::Hash docslukaramu-22/+61
Part of #29357. * merged "Derivable" and "How can I implement `Hash`?" sections into one "Implementing `Hash`" section to aid coherency * added an example for `#[derive(Hash)]` * moved part about relation between `Hash` and `Eq` into a new "`Hash` and `Eq`" section; changed wording to be more consistent with `HashMap` and `HashSet`'s * explicitly mentioned `#[derive(PartialEq, Eq, Hash)]` in the new section * changed method summaries for consistency, adding links and examples
