2017-07-10Disable big-endian simd in swap_nonoverlapping_bytesJosh Stone-1/+4
This is a workaround for #42778, which was git-bisected to #40454's optimizations to `mem::swap`, later moved to `ptr` in #42819. Natively compiled rustc couldn't even compile stage1 libcore on powerpc64 and s390x, but they work fine without this `repr(simd)`. Since powerpc64le works OK, it seems probably related to being big-endian. The underlying problem is not yet known, but this at least makes those architectures functional again in the meantime. cc @arielb1
2017-06-28Auto merge of #42819 - scottmcm:swap-nonoverlapping, r=sfacklerbors-0/+84
Reuse the mem::swap optimizations to speed up slice::rotate This is most helpful for compound types where LLVM didn't vectorize the loop. Highlight: bench slice::rotate_medium_by727_strings gets 38% faster. Exposes the swapping logic from PR https://github.com/rust-lang/rust/pull/40454 as `pub unsafe fn ptr::swap_nonoverlapping` under library feature `swap_nonoverlapping` https://github.com/rust-lang/rust/issues/42818. (The new method seemed plausible, and was the simplest way to share the logic. I'm not attached to it, though, so let me know if a different way would be better.)
2017-06-23Removed as many "```ignore" as possible.kennytm-6/+6
Replaced by adding extra imports, adding hidden code (`# ...`), modifying examples to be runnable (sorry Homura), specifying non-Rust code, and converting to should_panic, no_run, or compile_fail. Remaining "```ignore"s received an explanation why they are being ignored.

2017-05-04refactor NonZero, Shared, and Unique APIsAlexis Beingessner-44/+127
Major difference is that I removed Deref impls, as apparently LLVM has trouble maintaining metadata with a `&ptr -> &ptr` API. This was cited as a blocker for ever stabilizing this API. It wasn't that ergonomic anyway. * Added `get` to NonZero to replace Deref impl * Added `as_ptr` to Shared/Unique to replace Deref impl * Added Unique's `as_ref` and `as_mut` conveniences to Shared * Added `::empty()` convenience constructor for Unique/Shared * Deprecated `as_mut_ptr` on Shared in favour of `as_ptr` * Improved documentation of types Note that Shared now only refers to *mut, and not *const
2017-04-29Update stage0 bootstrap compilerAlex Crichton-5/+0
We've got a freshly minted beta compiler, let's update to use that on nightly! This has a few other changes associated with it as well * A bump to the rustc version number (to 1.19.0) * Movement of the `cargo` and `rls` submodules to their "proper" location in `src/tools/{cargo,rls}`. Now that Cargo workspaces support the `exclude` option this can work. * Updates of the `cargo` and `rls` submodules to their master branches. * Tweak to the `src/stage0.txt` format to be more amenable for Cargo version numbers. On the beta channel Cargo will bootstrap from a different version than rustc (e.g. the version numbers are different), so we need different configuration for this. * Addition of `dev` as a readable key in the `src/stage0.txt` format. If present then stage0 compilers are downloaded from `dev-static.rust-lang.org` instead of `static.rust-lang.org`. This is added to accomodate our updated release process with Travis and AppVeyor.

2016-11-04core::ptr: Specify issue for ptr_wrapping_offset featureUlrik Sverdrup-2/+2
2016-10-27core::ptr: Add .wrapping_offset() methodsUlrik Sverdrup-0/+80
.wrapping_offset() exposes the arith_offset intrinsic in the core module. This is the first step in making it possible to stabilize the interface later. `arith_offset` is a useful tool for developing iterators for two reasons: 1. `arith_offset` is used by the slice's iterator, the most important iterator in libcore, and it is natural that Rust users need the same power available to implement similar iterators. 2. It is a good way to implement raw pointer iterations with step greater than one. The name seems to fit the style of methods like "wrapping_add".

2016-03-01Rollup merge of #31965 - miqid:doc, r=steveklabnikSteve Klabnik-1/+1
Hello. Quite a few of the links in the `core` module concerning redirection to additional primitive type documentation are broken. I noticed in #30214 that there seemed to be a consensus with linking across to `std` module documentation from the `core` module. This is what I've done with the `core` modules for primitive types. If the changes here are good to go forward with, I'll happily tend to adding more documentation links for the extension traits in the aforementioned issue if need be. r? @steveklabnik
