@xmclark xmclark commented Feb 6, 2019

This PR is the first pass over syscalls.rs. In many cases, the signatures of libc functions differ slightly between the platforms. In many cases, different numeric type are used. This PR removes some explicit annotations and allows numeric types to be cast to the expected types. This moves us closer to windows support.

1026: Bump smallvec from 0.6.13 to 1.0.0 r=MarkMcCaskey a=dependabot-preview[bot]

Bumps [smallvec](https://github.com/servo/rust-smallvec) from 0.6.13 to 1.0.0.
<details>
<summary>Release notes</summary>

*Sourced from [smallvec's releases](https://github.com/servo/rust-smallvec/releases).*

> ## v1.0.0
>  * Requires Rust 1.36 or later.
>  * [breaking change] Use `MaybeUninit` to avoid possible undefined behavior ([#162](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/162), [#170](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/170)).
>  * [breaking change] The `drain` method now takes a range argument, just like the standard `Vec::drain` ([#145](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/145)).
>  * [breaking change] Remove the `unreachable` function and replace it with the new standard `unreachable_unchecked` function ([#164](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/164)).
>  * [breaking change] Use `no_std` by default. This crate depends only on `core` and `alloc` by default. If the optional `write` feature is enabled then it depends on `std` so that `SmallVec<[u8;_]>` can implement the `std::io::Write` trait ([#173](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/173)).
>  * [breaking change] Remove the deprecated `VecLike` trait ([#165](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/165)).
>  * Add support for 96-element small vectors, `SmallVec<[T; 96]>` ([#163](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/163)).
>  * Iterators now implement `FusedIterator` ([#172](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/172)).
>  * Indexing now uses the standard `SliceIndex` trait ([#166](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/166)).
>  * Add automatic fuzz testing and MIRI testing ([#168](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/168), [#162](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/162)).
>  * Update syntax and formatting to Rust 2018 standard ([#174](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/174), [#167](https://github-redirect.dependabot.com/servo/rust-smallvec/issues/167)).
