Implement checked_add_duration for SystemTime [Original discussion on the rust user forum](https://users.rust-lang.org/t/std-systemtime-misses-a-checked-add-function/21785) Since `SystemTime` is opaque there is no way to check if the result of an addition will be in bounds. That makes the `Add<Duration>` trait completely unusable with untrusted data. This is a big problem because adding a `Duration` to `UNIX_EPOCH` is the standard way of constructing a `SystemTime` from a unix timestamp. This PR implements `checked_add_duration(&self, &Duration) -> Option<SystemTime>` for `std::time::SystemTime` and as a prerequisite also for all platform specific time structs. This also led to the refactoring of many `add_duration(&self, &Duration) -> SystemTime` functions to avoid redundancy (they now unwrap the result of `checked_add_duration`). Some basic unit tests for the newly introduced function were added too. I wasn't sure which stabilization attribute to add to the newly introduced function, so I just chose `#[stable(feature = "time_checked_add", since = "1.32.0")]` for now to make it compile. Please let me know how I should change it or if I violated any other conventions. P.S.: I could only test on Linux so far, so I don't necessarily expect it to compile for all platforms.

2018-11-11std: Delete the `alloc_system` crateAlex Crichton-0/+85
This commit deletes the `alloc_system` crate from the standard distribution. This unstable crate is no longer needed in the modern stable global allocator world, but rather its functionality is folded directly into the standard library. The standard library was already the only stable location to access this crate, and as a result this should not affect any stable code.

2018-09-01Rollup merge of #53076 - QuietMisdreavus:cfg-rustdoc, r=GuillaumeGomezkennytm-1/+1
set cfg(rustdoc) when rustdoc is running on a crate When using `#[doc(cfg)]` to document platform-specific items, it's a little cumbersome to get all the platforms' items to appear all at once. For example, the standard library adds `--cfg dox` to rustdoc's command line whenever it builds docs, and the documentation for `#![feature(doc_cfg)]` suggests using a Cargo feature to approximate the same thing. This is a little awkward, because you always need to remember to set `--features dox` whenever you build documentation. This PR proposes making rustdoc set `#[cfg(rustdoc)]` whenever it runs on a crate, to provide an officially-sanctioned version of this that is set automatically. This way, there's a standardized way to declare that a certain version of an item is specifically when building docs. To try to prevent the spread of this feature from happening too quickly, this PR also restricts the use of this flag to whenever `#![feature(doc_cfg)]` is active. I'm sure there are other uses for this, but right now i'm tying it to this feature. (If it makes more sense to give this its own feature, i can easily do that.)

2018-08-15Start adding an `aarch64-pc-windows-msvc` targetAlex Crichton-4/+94
This commit adds the necessary definitions for target specs and such as well as the necessary support in libstd to compile basic `aarch64-pc-windows-msvc` binaries. The target is not currently built on CI, but it can be built locally with: ./configure --target=aarch64-pc-windows-msvc --set rust.lld ./x.py build src/libstd --target aarch64-pc-windows-msvc Currently this fails to build `libtest` due to a linker bug (seemingly in LLD?) which hasn't been investigate yet. Otherwise though with libstd you can build a hello world program (linked with LLD). I've not tried to execute it yet, but it at least links! Full support for this target is still a long road ahead, but this is hopefully a good stepping stone to get started. Points of note about this target are: * Currently defaults to `panic=abort` as support is still landing in LLVM for SEH on AArch64. * Currently defaults to LLD as a linker as I was able to get farther with it than I was with `link.exe`

There are a few places where we mention the replacement character in the docs, and it could be helpful for users to utilize the constant which is available in the standard library, so let’s link to it!
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.
