rust: Upgrade to version 1.66.1.
Pkgsrc changes:
* pkglint cleanups, bump bootstrap kits to 1.65.0.
* New target: mipsel-unknown-netbsd, for cpu=mips32 with soft-float.
* Managed to retain the build of aarch64_be, llvm needed a patch to
avoid use of neon instructions in the BE case (llvm doesn't support
use of neon in BE mode). Ref. patch to
src/llvm-project/llvm/lib/Support/BLAKE3/blake3_impl.h.
Also submitted upstream of LLVM to the BLAKE3 maintainers.
* The minimum gcc version is now 7.x, and that includes the
cross-compiler for the targets. For i386 this also needs to
/usr/include/gcc-7 include files in the target root, because
immintrin.h from gcc 5 is not compatible with gcc 7.x. This
applies for the targets where we build against a root from netbsd-8
(sparc64, powerpc, i386), and files/gcc-wrap gets a hack for this.
* Pick up tweak for -latomic inclusion from
https://github.com/rust-lang/rust/issues/104220
and
https://github.com/rust-lang/rust/pull/104572
* Retain ability to do 32-bit NetBSD, by changing from 64 to 32 bit
types in library/std/src/sys/unix/thread_parker/netbsd.rs.
* I've tried to get the "openssl-src" build with -latomic where it's
needed. I've introduced the "NetBSD-generic32" system type and use
it for the NetBSD mipsel target. There is another attempt to do
the same in the patch to vendor/openssl-sys/build/main.rs.
Upstream changes:
Version 1.66.1 (2023-01-10)
===========================
- Added validation of SSH host keys for git URLs in Cargo
([CVE-2022-46176](https://www.cve.org/CVERecord?id=CVE-2022-46176))
Version 1.66.0 (2022-12-15)
===========================
Language
--------
- [Permit specifying explicit discriminants on all `repr(Int)`
enums](https://github.com/rust-lang/rust/pull/95710/)
```rust
#[repr(u8)]
enum Foo {
A(u8) = 0,
B(i8) = 1,
C(bool) = 42,
}
```
- [Allow transmutes between the same type differing only in
lifetimes](https://github.com/rust-lang/rust/pull/101520/)
- [Change constant evaluation errors from a deny-by-default lint to a
hard error](https://github.com/rust-lang/rust/pull/102091/)
- [Trigger `must_use` on `impl Trait` for
supertraits](https://github.com/rust-lang/rust/pull/102287/) This
makes `impl ExactSizeIterator` respect the existing `#[must_use]`
annotation on `Iterator`.
- [Allow `..X` and `..=X` in
patterns](https://github.com/rust-lang/rust/pull/102275/)

assembly](https://github.com/rust-lang/rust/pull/103168/)
- [Update to Unicode 15](https://github.com/rust-lang/rust/pull/101912/)
- [Opaque types no longer imply lifetime
bounds](https://github.com/rust-lang/rust/pull/95474/) This is a
soundness fix which may break code that was erroneously relying on this
behavior.

- [`std::layout::Layout` size must not overflow `isize::MAX` when
rounded up to `align`](https://github.com/rust-lang/rust/pull/95295)
This also changes the safety conditions on
`Layout::from_size_align_unchecked`.
Stabilized APIs
---------------
- [`std::backtrace::Backtrace`]
(https://doc.rust-lang.org/stable/std/backtrace/struct.Backtrace.html)
- [`Bound::as_ref`]
(https://doc.rust-lang.org/stable/std/ops/enum.Bound.html#method.as_ref)
- [`std::io::read_to_string`]
(https://doc.rust-lang.org/stable/std/io/fn.read_to_string.html)
- [`<*const T>::cast_mut`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.cast_mut)
- [`<*mut T>::cast_const`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.cast_const)
These APIs are now stable in const contexts:
- [`<*const T>::offset_from`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.offset_from)
- [`<*mut T>::offset_from`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.offset_from)
Cargo
-----
- [Apply GitHub fast path even for partial hashes]
(https://github.com/rust-lang/cargo/pull/10807/)
- [Do not add home bin path to PATH if it's already there]
(https://github.com/rust-lang/cargo/pull/11023/)
- [Take priority into account within the pending queue]
(https://github.com/rust-lang/cargo/pull/11032/).
This slightly optimizes job scheduling by Cargo, with typically
small improvements on larger crate graph builds.
Compatibility Notes
-------------------
- [`std::layout::Layout` size must not overflow `isize::MAX` when
rounded up to `align`] (https://github.com/rust-lang/rust/pull/95295).
This also changes the safety conditions on
`Layout::from_size_align_unchecked`.
- [`PollFn` now only implements `Unpin` if the closure is `Unpin`]
(https://github.com/rust-lang/rust/pull/102737).
This is a possible breaking change if users were relying on the
blanket unpin implementation. See discussion on the PR for
details of why this change was made.
- [Drop ExactSizeIterator impl from std::char::EscapeAscii]
(https://github.com/rust-lang/rust/pull/99880)
This is a backwards-incompatible change to the standard library's
surface area, but is unlikely to affect real world usage.
- [Do not consider a single repeated lifetime eligible for elision
in the return type] (https://github.com/rust-lang/rust/pull/103450)
This behavior was unintentionally changed in 1.64.0, and this
release reverts that change by making this an error again.
- [Reenable disabled early syntax gates as future-incompatibility
lints] (https://github.com/rust-lang/rust/pull/99935/)
- [Update the minimum external LLVM to 13]
(https://github.com/rust-lang/rust/pull/100460/)
- [Don't duplicate file descriptors into stdio fds]
(https://github.com/rust-lang/rust/pull/101426/)
- [Sunset RLS](https://github.com/rust-lang/rust/pull/100863/)
- [Deny usage of `#![cfg_attr(..., crate_type = ...)]` to set the
crate type] (https://github.com/rust-lang/rust/pull/99784/)
This strengthens the forward compatibility lint
deprecated_cfg_attr_crate_type_name to deny.
- [`llvm-has-rust-patches` allows setting the build system to treat
the LLVM as having Rust-specific patches]
(https://github.com/rust-lang/rust/pull/101072)
This option may need to be set for distributions that are building
Rust with a patched LLVM via `llvm-config`, not the built-in
LLVM.
Internal Changes
----------------
These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.
- [Add `x.sh` and `x.ps1` shell scripts]
(https://github.com/rust-lang/rust/pull/99992/)
- [compiletest: use target cfg instead of hard-coded tables]
(https://github.com/rust-lang/rust/pull/100260/)
- [Use object instead of LLVM for reading bitcode from rlibs]
(https://github.com/rust-lang/rust/pull/98100/)
- [Enable MIR inlining for optimized compilations]
(https://github.com/rust-lang/rust/pull/91743)
This provides a 3-10% improvement in compiletimes for real world
crates. See [perf results]
(https://perf.rust-lang.org/compare.html?start=aedf78e56b2279cc869962feac5153b6ba7001ed&end=0075bb4fad68e64b6d1be06bf2db366c30bc75e1&stat=instructions:u).

lang/rust: update to version 1.62.1.
Pkgsrc changes:
* Bump required GCC to 7 (same as LLVM) to avoid ABI issues
Fixes native i386 and powerpc 8.x build w/pkgsrc LLVM 14

* Also unlimit stacksize
* Sync patches over from wip/rust
* Adjust line number in patches which had non-zero offsets.
* no longer pass -I/usr/pkg/include through via gcc-wrap script
when building natively. Attempt at fixing version skew with curl
package vs. internal version of curl (may not work...)
* The NetBSD bootstraps now use .xz compression.

* Default to using the internal LLVM when cross-building.
Upstream changes:
Version 1.62.1 (2022-07-19)
==========================
Rust 1.62.1 addresses a few recent regressions in the compiler and standard
library, and also mitigates a CPU vulnerability on Intel SGX.

Trait` return types.][98608]
* [The compiler fixed an incremental compilation bug with `async
fn` lifetimes.][98890]
* [Windows added a fallback for overlapped I/O in synchronous reads
and writes.][98950]
* [The `x86_64-fortanix-unknown-sgx` target added a mitigation for the
MMIO stale data vulnerability][98126], advisory [INTEL-SA-00615].

code pattern][96268]
Compiler
--------
- [linker: Stop using whole-archive on dependencies of dylibs][96436]
- [Make `unaligned_references` lint deny-by-default][95372]
This lint is also a future compatibility lint, and is expected to eventually
become a hard error.

- [Promote `x86_64-unknown-none` target to Tier 2\*][95705]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
---------
- [Move `CStr` to libcore, and `CString` to liballoc][94079]
- [Windows: Use a pipe relay for chaining pipes][95841]
- [Replace Linux Mutex and Condvar with futex based ones.][95035]
- [Replace RwLock by a futex based one on Linux][95801]
- [std: directly use pthread in UNIX parker implementation][96393]
Stabilized APIs
---------------
- [`bool::then_some`]
- [`f32::total_cmp`]
- [`f64::total_cmp`]
- [`Stdin::lines`]
- [`windows::CommandExt::raw_arg`]

Clippy
------
- [Create clippy lint against unexpectedly late drop for temporaries

Cargo
-----
- Added the `cargo add` command for adding dependencies to `Cargo.toml` from
the command-line.
[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-add.html)
- Package ID specs now support `name@version` syntax in addition to the
previous `name:version` to align with the behavior in `cargo add` and other
tools. `cargo install` and `cargo yank` also now support this syntax so the
version does not need to passed as a separate flag.
- The `git` and `registry` directories in Cargo's home directory (usually
`~/.cargo`) are now marked as cache directories so that they are not
included in backups or content indexing (on Windows).
- Added automatic `@` argfile support, which will use "response files" if the
command-line to `rustc` exceeds the operating system's limit.
Compatibility Notes
-------------------
- `cargo test` now passes `--target` to `rustdoc` if the specified target is
the same as the host target.
[#10594](https://github.com/rust-lang/cargo/pull/10594)
- [rustdoc: Remove .woff font files][96279]
- [Enforce Copy bounds for repeat elements while considering lifetimes][95819]
Internal Changes
----------------
- [Unify ReentrantMutex implementations across all platforms][96042]
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.

Version 1.61.0 (2022-05-19)
==========================
Language
--------
- [`const fn` signatures can now include generic trait bounds][93827]
- [`const fn` signatures can now use `impl Trait` in argument and return
position][93827]
- [Function pointers can now be created, cast, and passed around in a
`const fn`][93827]
- [Recursive calls can now set the value of a function's opaque
`impl Trait` return type][94081]
Compiler
--------
- [Linking modifier syntax in `#[link]` attributes and on the command
line, as well as the `whole-archive` modifier specifically, are now
supported][93901]
- [The `char` type is now described as UTF-32 in debuginfo][89887]
- The [`#[target_feature]`][target_feature] attribute
[can now be used with aarch64 features][90621]
- X86 [`#[target_feature = "adx"]` is now stable][93745]
Libraries
---------
- [`ManuallyDrop<T>` is now documented to have the same layout as `T`][88375]
- [`#[ignore = "#"]` messages are printed when running tests][92714]
- [Consistently show absent stdio handles on Windows as NULL handles][93263]
- [Make `std::io::stdio::lock()` return `'static` handles.][93965]
Previously, the creation of locked handles to stdin/stdout/stderr would
borrow the handles being locked, which prevented writing
`let out = std::io::stdout().lock();` because `out` would outlive
the return value of `stdout()`.
Such code now works, eliminating a common pitfall that affected many
Rust users.
- [`Vec::from_raw_parts` is now less restrictive about its inputs][95016]
- [`std::thread::available_parallelism` now takes cgroup quotas into
account.][92697] Since `available_parallelism` is often used to create a
thread pool for parallel computation, which may be CPU-bound for
performance, `available_parallelism` will return a value consistent with
the ability to use that many threads continuously, if possible.
For instance, in a container with 8 virtual CPUs but quotas only allowing
for 50% usage, `available_parallelism` will return 4.
Stabilized APIs
---------------
- [`Pin::static_mut`]
- [`Pin::static_ref`]
- [`Vec::retain_mut`]
- [`VecDeque::retain_mut`]
- [`Write` for `Cursor<[u8; N]>`][cursor-write-array]
- [`std::os::unix::net::SocketAddr::from_pathname`]
- [`std::process::ExitCode`] and [`std::process::Termination`].
The stabilization of these two API s now makes it possible for
programs to return errors from `main` with custom exit codes.
- [`std::thread::JoinHandle::is_finished`]
These APIs are now usable in const contexts:
- [`<*const T>::offset` and `<*mut T>::offset`][ptr-offset]
- [`<*const T>::wrapping_offset` and `<*mut T>::wrapping_offset`]
[ptr-wrapping_offset]
- [`<*const T>::add` and `<*mut T>::add`][ptr-add]
- [`<*const T>::sub` and `<*mut T>::sub`][ptr-sub]
- [`<*const T>::wrapping_add` and `<*mut T>::wrapping_add`][ptr-wrapping_add]
- [`<*const T>::wrapping_sub` and `<*mut T>::wrapping_sub`][ptr-wrapping_sub]
- [`<[T]>::as_mut_ptr`][slice-as_mut_ptr]
- [`<[T]>::as_ptr_range`][slice-as_ptr_range]
- [`<[T]>::as_mut_ptr_range`][slice-as_mut_ptr_range]
Cargo
-----
No feature changes, but see compatibility notes.
Compatibility Notes
-------------------
- Previously native static libraries were linked as `whole-archive` in
some cases, but now rustc tries not to use `whole-archive` unless
explicitly requested. This [change][93901] may result in linking errors
in some cases. To fix such errors, native libraries linked from the
command line, build scripts, or [`#[link]` attributes][link-attr] need to
- (more common) either be reordered to respect dependencies between them
(if `a` depends on `b` then `a` should go first and `b` second)
- (less common) or be updated to use the [`+whole-archive`] modifier.
- [Catching a second unwind from FFI code while cleaning up from a Rust
panic now causes the process to abort][92911]
- [Proc macros no longer see `ident` matchers wrapped in groups][92472]
- [The number of `#` in `r#` raw string literals is now required to be
less than 256][95251]
- [When checking that a dyn type satisfies a trait bound, supertrait
bounds are now enforced][92285]
- [`cargo vendor` now only accepts one value for each `--sync` flag]
[cargo/10448]
- [`cfg` predicates in `all()` and `any()` are always evaluated to detect
errors, instead of short-circuiting.][94295] The compatibility
considerations here arise in nightly-only code that used the
short-circuiting behavior of `all` to write something like
`cfg(all(feature = "nightly", syntax-requiring-nightly))`, which
will now fail to compile. Instead, use either `cfg_attr(feature
= "nightly", ...)` or nested uses of `cfg`.
- [bootstrap: static-libstdcpp is now enabled by default, and can
now be disabled when llvm-tools is enabled][94832]
Internal Changes
----------------
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.
- [debuginfo: Refactor debuginfo generation for types][94261]
- [Remove the everybody loops pass][93913]

Upgrade rust to version 1.31.1. Pkgsrc changes: * Sadly, I had to reinstate the "make tar files" rust code to make it possible to build cross-compiled bootstrap kits. * Add an adjustable "BUILD_TARGET", "dist" for cross-building a bootstrap kit, "build" for a normal native build. * New bootstrap kits built for NetBSD/powerpc, NetBSD/earmv7hf, and NetBSD/sparc64 version 1.31.1. * gcc-wrap script amended to also drop -Wl,--enable-new-dtags (so it could be used outside pkgsrc) * Worked around use of AtomicU64 in release build tool (ugly band-aid patch). Some platforms lack support for that type and associated operations. Upstream changes: - [Fix Rust failing to build on `powerpc-unknown-netbsd`][56562] - [Fix broken go-to-definition in RLS][rls/1171] - [Fix infinite loop on hover in RLS][rls/1170] [56562]: https://github.com/rust-lang/rust/pull/56562 [rls/1171]: https://github.com/rust-lang/rls/issues/1171 [rls/1170]: https://github.com/rust-lang/rls/pull/1170

Upgrade rust to version 1.29.2. Upstream changes: * Workaround for an aliasing-related LLVM bug, which caused miscompilation. * The rls-preview component on the windows-gnu targets has been restored. Pkgsrc changes: * More commented-out settings for cross builds on NetBSD. * Bump bootstrap kit versions to 1.29.2 for powerpc, sparc64 and earm7hf. Anyone up for testing for earm7hf? * Because the built-in versions of libgit2, libssh2 and curl can no longer be built with the pkgsrc-provided headers for those packages (due to version skew; the built-in versions have been updated to un-released newer code), the buildlink3.mk files for those packages have been commented out. * Similarly, to avoid using the native pkgsrc host's headers when cross- building, the gcc-wrap script has been adjusted to also re-point /usr/pkg/include into the destination's root (where those above pacakges are not to be installed). * Also have the gcc-wrap script deal with "-I dir" style directives, and re-point these also into the destination's root. * One patch has been integrated upstream, so removed here.

Diff to previous 1.1 (colored)
Add pointers to (so far untested) bootstrap kits for sparc64 and earmv7hf. Prepare wrapper script handling for use of clang (not yet fully verified). Adjust the cross-compiler wrapper script to improve the handling when used as the linker: * Insert "linker tweaks" before first -L or -l * Handle "-L arg" style as well as "-Larg" * Add "-Wl,-rpath-link" to the linker tweaks just to be sure... Bump PKGREVISION.
Revision 1.1 / (download) - annotate - [select for diffs], Sat Oct 13 10:03:37 2018 UTC (5 years, 6 months ago) by he
Branch: MAIN
Add the bits required to build rust on NetBSD/powerpc ports, and point to the bootstrap kit for NetBSD/powerpc I'm hosting at the moment. Also add the bits I used when cross-building the NetBSD/powerpc rust on amd64, commented out, as well as the gcc / c++ wrapper script I used in the process. The changes affecting other ports are: * We now add LD_LIBRARY_PATH in the make environment, so that if the bootstrap kit binaries and shared libraries don't have the $ORIGIN-style RPATH entries, it will still work * The bootstrap.py script has been changed to turn off the generation of debuginfo in "RUSTFLAGS"; for some so far unknown reason, the NetBSD/powerpc rust will not build if you ask for debug info. This could perhaps have been made OS-variant dependent, but isn't at the moment. So .. bump PKGREVISION.
