2016-05-20Auto merge of #33318 - alexcrichton:hashmap-seed, r=aturonbors-2/+27
std: Cache HashMap keys in TLS This is a rebase and extension of #31356 where we not only cache the keys in thread local storage but we also bump each key every time a new `HashMap` is created. This should give us a nice speed bost in creating hash maps along with retaining the property that all maps have a nondeterministic iteration order. Closes #27243

Reword the short diagnostic for E0509 Saying that a type *implements* a trait is much more idiomatic than saying it *defines* the trait.

2016-05-20Auto merge of #33729 - alexcrichton:patch-libbacktrace, r=sfacklerbors-4/+31
std: Backport a libbacktrace soundness fix This is a backport of gcc-mirror/gcc@047a1c2f which is a soundness fix for when a backtrace is generated on executables that do not have debug information.
2016-05-20Auto merge of #33553 - alexcrichton:cdylibs, r=brsonbors-94/+283
rustc: Add a new crate type, cdylib This commit is an implementation of [RFC 1510] which adds a new crate type, `cdylib`, to the compiler. This new crate type differs from the existing `dylib` crate type in a few key ways: * No metadata is present in the final artifact * Symbol visibility rules are the same as executables, that is only reachable `extern` functions are visible symbols * LTO is allowed * All libraries are always linked statically This commit is relatively simple by just plubming the compiler with another crate type which takes different branches here and there. The only major change is an implementation of the `Linker::export_symbols` function on Unix which now actually does something. This helps restrict the public symbols from a cdylib on Unix. With this PR a "hello world" `cdylib` is 7.2K while the same `dylib` is 2.4MB, which is some nice size savings! [RFC 1510]: https://github.com/rust-lang/rfcs/pull/1510 Closes #33132

2016-05-19Clarify the English translation of `?Sized`Postmodern-4/+3
* It wasn't clear whether `?Sized` meant "not `Sized`" or "`Sized` or not `Sized`". According to #rust IRC, it does indeed mean "`Sized` or not `Sized`". * Use the same language as [Trait std::marker::Sized](https://doc.rust-lang.org/std/marker/trait.Sized.html) about how `Sized` is implicitly bound.

2016-05-19Auto merge of #33103 - ranma42:escape-unicode-last, r=alexcrichtonbors-0/+45
Implement `last` for `EscapeUnicode` The implementation is quite trivial as the last character is always `'{'`. As a side-effect it also improves the implementation of `last` for `EscapeUnicode`. Part of #24214, split from #31049. Maybe this (and the other changes that I will split from #31049) should wait for a test like `ed_iterator_specializations` to be added. Would it be sufficient to do the same for each possible escape length?

Rust syntax coloring for some ignore, should-panic and no-run snippets. In the book, some code blocks were missing the `rust` specifier which is needed for them to highlight correctly.

2016-05-19Rollup merge of #33708 - nham:zero-elided-lifetimes, r=sanxiynManish Goregaokar-9/+48
Only print parameters with elided lifetimes in elision error messages. When displaying the function parameters for a lifetime elision error message, this changes it to first filter out the parameters that don't have elided lifetimes. Fixes #30255.
2016-05-19Rollup merge of #33705 - lqd:rustdoc-version-tooltip, r=GuillaumeGomezManish Goregaokar-2/+3
rustdoc: Make the #[stable(since)] version attribute clearer with a tooltip Rustdoc's new 'since' version placement only shows the version number in which the item was marked stable. This gains space but might make the meaning of this version string less clear in the docs, so I tried to bring some explicitness in a tooltip.

std: Update libc submodule Brings in a fix where `-lutil` is no longer passed for musl targets, lifting the need for a musl toolchain to be installed again. Closes #33608

2016-05-19Rollup merge of #33611 - vvanders:master, r=steveklabnikManish Goregaokar-0/+47
Add a note about Higher-Ranked Trait Bounds in docs on Closures. I hit a snag with lifetimes a few days ago and it wasn't until @birkenfeld pointed out Higher-Ranked Trait Bounds that I was able to solve the issue involving lifetimes on closure traits. This adds a small section in the book so that other users can find it. r? @steveklabnik
