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.
A function that has no prologue cannot be reasonably expected to support debuginfo. In fact, the existing code (before this patch) would generate invalid instructions that caused crashes. We can solve this easily by just not emitting the debuginfo in this case. Fixes rust-lang#42779 cc rust-lang#32408
This pulls in a fix for the install script on some tr(1) implementations, as well as an update to use `anyhow` instead of `failure` for error handling.
This adds `read_exact_at` and `write_all_at` to WASI's `FileExt`, similar to the Unix versions of the same names.
Rename the existing read_at/write_at to read_vectored_at/write_vectored_at, for consistency with libstd's read_vectored/write_vectored. And, introduce new read_at/write_at functions which take a single buffer, similar to all other targets which provide these functions, so this will make it easier for applications to share code between WASI and other targets. Note that WASI's FileExt is currently unstable.
As of rust-lang#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.
It has a single call site and having it as a separate (higher-order!) function makes the code harder to read.
This makes the two versions (parallel and non-parallel) more similar to each other.
Accept tuple.0.0 as tuple indexing (take 2) If we expect something identifier-like when parsing a field name after `.`, but encounter a float token, we break that float token into parts, similarly to how we break `&&` into `&` `&`, or `<<` into `<` `<`, etc. An alternative to rust-lang#70420.
Stabilize `transmute` in constants and statics but not const fn cc rust-lang#53605 (leaving issue open so we can add `transmute` to `const fn` later) Previous attempt: rust-lang#64011 r? @RalfJung cc @rust-lang/wg-const-eval
…fJung Stabilize casts and coercions to `&[T]` in const fn Part of rust-lang#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

…, r=alexcrichton Add `read_exact_at` and `write_all_at` to WASI's `FileExt` This adds `read_exact_at` and `write_all_at` to WASI's `FileExt`, similar to the Unix versions of the same names.
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.
…lacrum 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.
…atsakis Only add CFGuard on `windows-msvc` targets As @ollie27 pointed out in rust-lang#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).
Suppress debuginfo on naked function arguments A function that has no prologue cannot be reasonably expected to support debuginfo. In fact, the existing code (before this patch) would generate invalid instructions that caused crashes. We can solve this easily by just not emitting the debuginfo in this case.

…=Mark-Simulacrum ⬆️ rust-analyzer This updates rust-analyzer submodule to the latest release. I plan to do that every Monday after rust-analyzer release (about 16:00 CET). This is semi-automated by https://github.com/rust-analyzer/rust-analyzer/pull/5253/files#diff-c06f6a9cbd0ad2421bcc2ddc28805457R77-R100. Who would be the appropriate person to r? on Mondays?
