2018-08-09Auto merge of #53108 - RalfJung:mutex, r=alexcrichtonbors-6/+38
clarify partially initialized Mutex issues Using a `sys_common::mutex::Mutex` without calling `init` is dangerous, and yet there are some places that do this. I tried to find all of them and add an appropriate comment about reentrancy. I found two places where (I think) reentrancy can actually occur, and was not able to come up with an argument for why this is okay. Someone who knows `io::lazy` and/or `sys_common::at_exit_imp` should have a careful look at this.

Remove references to `StaticMutex` which got removed a while ago `StaticMutex` got removed two years ago with https://github.com/rust-lang/rust/pull/34705, but still got referenced in some comments and even an error explanation.

Specify reentrancy gurantees of `Once::call_once` I don't think the docs are clear about what happens in the following code ```rust static INIT: Once = ONCE_INIT; INIT.call_once(|| INIT.call_once(|| println!("huh?"))); ``` [Playground](https://play.rust-lang.org/?gist=15dde1f68a6ede263c7250c36977eade&version=stable&mode=debug&edition=2015) Let's "specify" the behavior to make it clear that the current behavior (deadlock I think?) is not a strict guarantee.

2018-08-02Auto merge of #52847 - upsuper:thread-stack-reserve, r=alexcrichtonbors-1/+4
Don't commit thread stack on Windows On Windows, there is a system level resource limitation called commit limit, which is roughly the sum of physical memory + paging files[1]. `CreateThread` by default commits the stack size[2], which unnecessarily takes such resource from the shared limit. This PR changes it to only reserve the stack size rather than commit it. Reserved memory would only take the address space of the current process until it's actually accessed. This should make the behavior on Windows match other platforms, and is also a pretty standard practice on Windows nowadays.

Add targets for HermitCore (https://hermitcore.org) to the Rust compiler and port libstd to it. As a start, the port uses the simplest possible configuration (no jemalloc, abort on panic) and makes use of existing Unix-specific code wherever possible. It adds targets for x86_64 (current main HermitCore platform) and aarch64 (HermitCore platform under development). Together with the patches to "liblibc" (https://github.com/rust-lang/libc/pull/1048) and llvm (https://github.com/rust-lang/llvm/pull/122), this enables HermitCore applications to be written in Rust.
