2020-07-11Rollup merge of #74167 - jclulow:illumos-linker-eh-frame-hdr-fix, r=petrochenkovManish Goregaokar-1/+1
linker: illumos ld does not support --eh-frame-hdr As of rust-lang/rust#73564, the --eh-frame-hdr flag is unconditionally passed to linkers on many platforms. The illumos link editor does not currently support this flag. The linker machinery in the Rust toolchain currently seems to use the (potentially cross-compiled) target to choose linker flags, rather than looking at what might be running on the build system. Disabling the flag for all illumos/Solaris targets seems like the best we can do for now without more serious surgery.
2020-07-11Rollup merge of #74116 - arlosi:aarch64build, r=pietroalbiniManish Goregaokar-10/+25
Fix cross compilation of LLVM to aarch64 Windows targets When cross-compiling, the LLVM build system recurses to build tools that need to run on the host system. However, since we pass cmake defines to set the compiler and target, LLVM still compiles these tools for the target system, rather than the host. The tools then fail to execute during the LLVM build. This change sets defines for the tools that need to run on the host (llvm-nm, llvm-tablegen, and llvm-config), so that the LLVM build does not attempt to build them, and instead relies on the tools already built. If compiling with clang-cl, adds the `--target` option to specify the target triple. MSVC compilers do not require this, since there is a separate compiler binary for each cross-compilation target. Related issue: #72881 Requires LLVM change: rust-lang/llvm-project#67
2020-07-11Rollup merge of #74066 - thomcc:optimize-is-ascii, r=nagisaManish Goregaokar-2/+242
Optimize is_ascii for str and [u8]. This optimizes the `is_ascii` function for `[u8]` and `str`. I've been surprised this wasn't done for a while, so I just did it. Benchmarks comparing before/after look like: ``` test ascii::long_readonly::is_ascii_slice_iter_all ... bench: 174 ns/iter (+/- 79) = 40172 MB/s test ascii::long_readonly::is_ascii_slice_libcore ... bench: 16 ns/iter (+/- 5) = 436875 MB/s test ascii::medium_readonly::is_ascii_slice_iter_all ... bench: 12 ns/iter (+/- 3) = 2666 MB/s test ascii::medium_readonly::is_ascii_slice_libcore ... bench: 2 ns/iter (+/- 0) = 16000 MB/s test ascii::short_readonly::is_ascii_slice_iter_all ... bench: 3 ns/iter (+/- 0) = 2333 MB/s test ascii::short_readonly::is_ascii_slice_libcore ... bench: 4 ns/iter (+/- 0) = 1750 MB/s ``` (Taken on a x86_64 macbook 2.9 GHz Intel Core i9 with 6 cores) Where `is_ascii_slice_iter_all` is the old version, and `is_ascii_slice_libcore` is the new. I tried to document the code well, so hopefully it's understandable. It has fairly exhaustive tests ensuring size/align doesn't get violated -- because `miri` doesn't really help a lot for this sort of code right now, I tried to `debug_assert` all the safety invariants I'm depending on. (Of course, none of them are required for correctness or soundness -- just allows us to test that this sort of pointer manipulation is sound and such). Anyway, thanks. Let me know if you have questions/desired changes.
2020-07-11Rollup merge of #73715 - MaulingMonkey:pr-natvis-tuples, r=AmanieuManish Goregaokar-3/+334
debuginfo: Mangle tuples to be natvis friendly, typedef basic types These changes are meant to unblock rust-lang/rust#70052 "Update hashbrown to 0.8.0" by allowing the use of `tuple<u64, u64>` as a .natvis expression in MSVC style debuggers (MSVC, WinDbg, CDB, etc.) * f8eb81b does the actual mangling of `(u64, u64)` -> `tuple<u64, 64>` * 24a728a allows `u64` to resolve (fixing `$T1` / `$T2` when used to visualize `HashMap<u64, u64, ...>`)

2020-07-10Rollup merge of #74161 - tblah:riscv64gc-dockerfile-improvment, ↵Manish Goregaokar-5/+5
r=Mark-Simulacrum Fix disabled dockerfiles When the dockerfiles were moved into the host-x86_64 directory, paths for COPY commands were updated with the new host-x86_64/ prefix. This suggested that the intended context was src/ci/docker. However, the context for disabled docker images was src/ci/docker/host-x86_64. This broke the new paths and prevented src/ci/docker/scripts from being included in the context at all. This commit corrects this context allowing docker to find the files it needs for COPY commands. Also includes a quick fix to riscv recommended by @bjorn3

2020-07-10Rollup merge of #74103 - ajpaverd:cfguard-msvc-only, r=nikomatsakisManish Goregaokar-19/+36
Only add CFGuard on `windows-msvc` targets As @ollie27 pointed out in #73893, the `cfguard` module flag causes incorrect behavior on `windows-gnu` targets. This patch restricts rustc to only add this flag for `windows-msvc` targets (this may need to be changed if other linkers gain support for CFGuard).
2020-07-10Rollup merge of #74100 - lzutao:strip-bootstrap, r=Mark-SimulacrumManish Goregaokar-10/+10
Use str::strip* in bootstrap This is technically a breaking change, replacing the use of `trim_start_matches` with `strip_prefix`. However, because in `rustc -Vv` output there are no lines starting with multiple "release:", this should go unnoticed in practice.
2020-07-10Rollup merge of #74099 - jonhoo:deque-range, r=dtolnayManish Goregaokar-13/+163
Add VecDeque::range* methods This patch adds `VecDeque::range` and `VecDeque::range_mut` to provide iterators over a sub-range of a `VecDeque`. This behavior can be emulated with `skip` and `take`, but directly providing a `Range` is more ergonomic. This also partially makes up for `VecDeque`'s lack of `SliceIndex` support.

2020-07-10Rollup merge of #73862 - oli-obk:const_array_to_slice, r=RalfJungManish Goregaokar-32/+34
Stabilize casts and coercions to `&[T]` in const fn Part of #64992 There was never a reason to not stabilize this, we just accidentally prevented them when we implemented the `min_const_fn` feature that gave us `const fn` on stable. This PR stabilizes these casts (which are already stable in `const` outside `const fn`), while keeping all other unsizing casts (so `T` -> `dyn Trait`) unstable within const fn. These casts have no forward compatibility concerns with any future features for const eval and users were able to use them under the `const_fn` feature gate already since at least the miri merger, possibly longer. r? @rust-lang/lang
2020-07-10Rollup merge of #72303 - yoshuawuyts:future-poll-fn, r=dtolnayManish Goregaokar-0/+70
Add core::future::{poll_fn, PollFn} This is a sibling PR to #70834, adding `future::poll_fn`. This is a small helper function that helps bridge the gap between "poll state machines" and "async/await". It was first introduced in [futures@0.1.7](https://docs.rs/futures/0.1.7/futures/future/fn.poll_fn.html) in December of 2016, and has been tried and tested as part of the ecosystem for the past 3.5 years. ## Implementation Much of the same reasoning from #70834 applies: by returning a concrete struct rather than an `async fn` we get to mark the future as `Unpin`. It also becomes named which allows storing it in structs without boxing. This implementation has been modified from the implementation in `futures-rs`. ## References - [`futures::future::poll_fn`](https://docs.rs/futures/0.3.5/futures/future/fn.poll_fn.html) - [`async_std::future::poll_fn`](https://docs.rs/async-std/1.5.0/async_std/future/fn.poll_fn.html)
