Use arrayvec 0.7, drop smallvec 0.6
With the arrival of min const generics, many alt-vec libraries have
updated to use it in some way and arrayvec is no exception. Use the
latest with minor refactoring.
Also, rustc_workspace_hack is the only user of smallvec 0.6 in the
entire tree, so drop it.
This lets me build against llvm/main as of March 23rd, 2021. I'm not
entirely sure this is _correct_, but it appears to be functionally
identical to what was done in LLVM: existing callsites of
setInlineAsmDiagnosticHandler were moved to SetDiagnosticHandler() on
the context object, which we already set up in both places that we
called setInlineAsmDiagnosticHandler().

Remove `sys::args::Args::inner_debug` and use `Debug` instead
This removes the method `sys::args::Args::inner_debug` on all platforms and implements `Debug` for `Args` instead.
I believe this creates a more natural API for the different platforms under `sys`: export a type `Args: Debug + Iterator + ...` vs. `Args: Iterator + ...` and with a method `inner_debug`.
Check for intrinsics before coercing to a function pointer
Return an error if coercing function items / non-capturing closures
to a common function pointer type would require reifying an intrinsic.
Turns ICE reported in #84297 into a proper error.
Move `sys_common::rwlock::StaticRWLock` etc. to `sys::unix::rwlock`
This moves `sys_common::rwlock::StaticRwLock`, `RWLockReadGuard` and `RWLockWriteGuard` to `sys::unix::rwlock`. They are already `#[cfg(unix)]` and don't need to be in `sys_common`.
Implement indexing slices with pairs of core::ops::Bound<usize>
Closes#49976.
I am not sure about code duplication between `check_range` and `into_maybe_range`. Should be former implemented in terms of the latter? Also this PR doesn't address code duplication between `impl SliceIndex for Range*`.
`single_component_path_imports`: ignore `pub(crate) use some_macro;`
Fixes#7106
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: Ignore exporting a macro within a crate using `pub(crate) use some_macro;` for [`single_component_path_imports`]
Unused io amount detects `.read().ok()?`
fixes#7096
changelog: unused_io_amount now detect expertion like `.read().ok()?`, `.read().or_else(|err| ...)?` and similar expressions.
These were made public in 3105bcfdc11030abf9855af7a693cbf904460813. This
is so long ago I doubt anyone remembers why they're public. No one uses
them, including in-tree tools.
Add missing information on what standard-library features are supported
by the UEFI targets.
All current UEFI targets (which is i686 and x86_64) only support no_std
cross-compilations. `std` support has not been worked on and is unlikely
to emerge anytime soon, due to the much restricted environment that UEFI
provides.
Switch transmute_ptr_to_ptr to "pedantic" class.
Per discussion in https://github.com/rust-lang/rust-clippy/issues/6372, this lint has significant false positives.
changelog: transmute_ptr_to_ptr defaults to "allow".
bootstrap: Restore missing --bulk-dirs for rust-docs, rustc-docs
The `--bulk-dirs` argument was removed for rust-docs in commit c768ce138427b1844c1f6594daba9c0e33928032 and rustc-docs in commit 8ca46fc7a83734c9622f11f25d16b82316f44bcc (#79788), presumably by mistake; that slowed down installation of rust-docs from under a second to some twenty *minutes*. Restoring `--bulk-dirs` reverses this slowdown.
Fixes#80684.

bump jobserver dependency
the newest jobserver version should slightly reduce context switches
in highly parallel build environments on linux kernels >= 5.6
