Originally added in rust-lang#55935 to test build times, this was reverted in rust-lang#56201 due to a belief that it caused the exit code 259 spurious errors. We've since learned, however, that the 259 exit code is likely not related to this image update as we're getting it in a number of locations now. VS2017 looks like it may be required to compile LLVm in the near future, notably discovered by rust-lang#58408 where we attempted to update LLVM.
This was one of the unresolved questions of rust-lang/rfcs#2480. As the RFC says this is maybe not useful in the sense that we are unlikely to ever have a second version, but making the crate a true subset makes one less issue to think about if we stabilize it and later want to merge standard library crates and have Cargo feature flags to enable or disable parts of the `std` crate. See also discussion in rust-lang#58175
Ensure the core::ffi::VaList structure passes the improper_ctypes lint.
… to separate it from that of the crate. New tracking issue: rust-lang#58935
There's lots of comments in the code, but the main gist of this commit is that the acquisition of the global malloc lock on the `wasm32-unknown-unknown` target when threads are enabled will not spin on contention rather than block.
MIPS r6 is quite different with the previous version. It use some new target triples: mipsisa32r6-unknown-linux-gnu mipsisa32r6el-unknown-linux-gnu mipsisa64r6-unknown-linux-gnuabi64 mipsisa64r6el-unknown-linux-gnuabi64 This patch has been tested with Debian Port for mips64r6el, and the support of these triples also is included in llvm: https://reviews.llvm.org/rGe58c45a695f39004710b6ce940d489fee800dbd3
A `Def::Variant` should be considered as a function in mir pretty
printing. Each variant has a constructor that we must print.
Given the following enum definition:
```
pub enum TestMe {
X(usize),
}
```
We will need to generate a constructor for the variant `X` with a
signature that looks something like the following:
```
fn TestMe::X(_1: usize) -> TestMe;
```
…-restriction, r=alexcrichton Remove restriction on isize/usize in repr(simd) As discussed in rust-lang#55078, there's no known reason for this restriction. It's unlikely that repr(simd) will be stabilized in its current form, but might as well remove some restrictions on it. This removes the branch in `is_machine` which returns false for these types. `is_machine` is only used for the repr(simd) type validation check.
Output diagnostic information for rustdoc Use the information same as rustc.
Improved test output
…=oli-obk Reduce a Code Repetition Related to Bit Operation This PR is related to [rust-lang#49937](rust-lang#49937). Should I do more commits about [`FIXME(49937)`](https://github.com/rust-lang/rust/search?q=FIXME%2849937%29&unscoped_q=FIXME%2849937%29) in this PR?
Add x86_64 musl host to the manifest @alexcrichton r? Probably too late for rust-lang#59207
…ntril Option and Result: Add references to documentation of as_ref and as_mut This makes the documentation more consistent with that of `Pin::as_ref` which converts "from `&Pin<Pointer<T>>` to `Pin<&t>`". This generally makes it clearer that the reference is going inside the option.
Add release notes for PR rust-lang#56243 Fixes rust-lang#58907
Stabilize Option::copied closes rust-lang#57126
