Upstream changes:
Version 1.52.1 (2021-05-10)
============================
This release disables incremental compilation, unless the user has explicitly
opted in via the newly added RUSTC_FORCE_INCREMENTAL=1 environment variable.
This is due to the widespread, and frequently occuring, breakage encountered by
Rust users due to newly enabled incremental verification in 1.52.0. Notably,
Rust users **should** upgrade to 1.52.0 or 1.52.1: the bugs that are detected by
newly added incremental verification are still present in past stable versions,
and are not yet fixed on any channel. These bugs can lead to miscompilation of
Rust binaries.
These problems only affect incremental builds, so release builds with Cargo
should not be affected unless the user has explicitly opted into incremental.
Debug and check builds are affected.
See [84970] for more details.

Version 1.52.0 (2021-05-06)
============================
Language
--------
- [Added the `unsafe_op_in_unsafe_fn` lint, which checks whether
the unsafe code in an `unsafe fn` is wrapped in a `unsafe`
block.][79208] This lint is allowed by default, and may become
a warning or hard error in a future edition.
- [You can now cast mutable references to arrays to a pointer of
the same type as the element.][81479]
Compiler
--------
- [Upgraded the default LLVM to LLVM 12.][81451]
Added tier 3\* support for the following targets.
- [`s390x-unknown-linux-musl`][82166]
- [`riscv32gc-unknown-linux-musl` & `riscv64gc-unknown-linux-musl`][82202]
- [`powerpc-unknown-openbsd`][82733]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
---------
- [`OsString` now implements `Extend` and `FromIterator`.][82121]
- [`cmp::Reverse` now has `#[repr(transparent)]` representation.][81879]
- [`Arc<impl Error>` now implements `error::Error`.][80553]
- [All integer division and remainder operations are now `const`.][80962]
Stabilised APIs
-------------
- [`Arguments::as_str`]
- [`char::MAX`]
- [`char::REPLACEMENT_CHARACTER`]
- [`char::UNICODE_VERSION`]
- [`char::decode_utf16`]
- [`char::from_digit`]
- [`char::from_u32_unchecked`]
- [`char::from_u32`]
- [`slice::partition_point`]
- [`str::rsplit_once`]
- [`str::split_once`]
The following previously stable APIs are now `const`.
- [`char::len_utf8`]
- [`char::len_utf16`]
- [`char::to_ascii_uppercase`]
- [`char::to_ascii_lowercase`]
- [`char::eq_ignore_ascii_case`]
- [`u8::to_ascii_uppercase`]
- [`u8::to_ascii_lowercase`]
- [`u8::eq_ignore_ascii_case`]
Rustdoc
-------
- [Rustdoc lints are now treated as a tool lint, meaning that
lints are now prefixed with `rustdoc::` (e.g.
`#[warn(rustdoc::non_autolinks)]`).][80527] Using the old style
is still allowed, and will become a warning in a future release.
- [Rustdoc now supports argument files.][82261]
- [Rustdoc now generates smart punctuation for documentation.][79423]
- [You can now use "task lists" in Rustdoc Markdown.][81766] E.g.
```markdown
- [x] Complete
- [ ] Todo
```
Misc
----
- [You can now pass multiple filters to tests.][81356] E.g.
`cargo test -- foo bar` will run all tests that match `foo` and `bar`.
- [Rustup now distributes PDB symbols for the `std` library on Windows,
allowing you to see `std` symbols when debugging.][82218]
Internal Only
-------------
These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.
- [Check the result cache before the DepGraph when ensuring queries][81855]
- [Try fast_reject::simplify_type in coherence before doing full check][81744]
- [Only store a LocalDefId in some HIR nodes][81611]
- [Store HIR attributes in a side table][79519]
Compatibility Notes
-------------------
- [Cargo build scripts are now forbidden from setting
`RUSTC_BOOTSTRAP`.][cargo/9181]
- [Removed support for the `x86_64-rumprun-netbsd` target.][82594]
- [Deprecated the `x86_64-sun-solaris` target in favor of
`x86_64-pc-solaris`.][82216]
- [Rustdoc now only accepts `,`, ` `, and `\t` as delimiters for specifying
languages in code blocks.][78429]
- [Rustc now catches more cases of `pub_use_of_private_extern_crate`][80763]
- [Changes in how proc macros handle whitespace may lead to panics
when used with older `proc-macro-hack` versions. A `cargo update` should
be sufficient to fix this in all cases.][84136]

Some patch(1) implementations, such as OpenBSD patch and GNU patch,
choose the file name with the fewest path components if neither the
old or new file exist. This missing slash causes the old name
(compiler/rustc_target/src/speci586_unknown_netbsd.rs.orig) to have
fewer components, so it is created instead of the new name as
intended.
This results in build error when one of these patch(1) implementations
is used:
error[E0583]: file not found for module `i586_unknown_netbsd`
|
|
Pkgsrc changes:
* Add support for the big-endian arm64 NetBSD target (aarch64_be).
* On NetBSD/i386, use the i586 (pentium) bootstrap kit variant in
preference to i686.
* Adjust patches, re-compute line offsets, re-compute crate checksums.
* Remove a patch which was either integrated upstream and/or no longer
applies.
* Bump bootstraps to 1.50.0.
* Move conditionals until after bsd.prefs.mk so that they work...
* Default to "dist" build target if cross-compiling, but allow
also to override via rust.BUILD_TARGET.
* Allow overriding MAKE_JOBS_SAFE via rust.MAKE_JOBS_SAFE if you
want a different trade-off between occasional breakage and performance.
* Adjust platform.mk according to work already done in wip/rust/
* Add a patch to optimize the install.sh script used to install binary
bootstraps to not do so many forks; use case/esac and parameter expansion
instead of grep, sed and cut.
* Drop building documentation for the binary bootstrap kits. This will
also impact the lang/rust-bin package. For full documentation, build
or install lang/rust as a package.
Upstream changes:
Version 1.51.0 (2021-03-25)
============================
Language
--------
- [You can now parameterize items such as functions, traits, and
`struct`s by constant values in addition to by types and
lifetimes.][79135] Also known as "const generics" E.g. you can
now write the following. Note: Only values of primitive integers,
`bool`, or `char` types are currently permitted.
```rust
struct GenericArray<T, const LENGTH: usize> {
inner: [T; LENGTH]
}
impl<T, const LENGTH: usize> GenericArray<T, LENGTH> {
const fn last(&self) -> Option<&T> {
if LENGTH == 0 {
None
} else {
Some(&self.inner[LENGTH - 1])
}
}
}
```
Compiler
--------
- [Added the `-Csplit-debuginfo` codegen option for macOS platforms.][79570]
This option controls whether debug information is split across
multiple files or packed into a single file. **Note** This option
is unstable on other platforms.
- [Added tier 3\* support for `aarch64_be-unknown-linux-gnu`,
`aarch64-unknown-linux-gnu_ilp32`, and
`aarch64_be-unknown-linux-gnu_ilp32` targets.][81455]
- [Added tier 3 support for `i386-unknown-linux-gnu` and
`i486-unknown-linux-gnu` targets.][80662]
- [The `target-cpu=native` option will now detect individual features
of CPUs.][80749]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
---------
- [`Box::downcast` is now also implemented for any `dyn Any + Send
+ Sync` object.][80945]
- [`str` now implements `AsMut<str>`.][80279]
- [`u64` and `u128` now implement `From<char>`.][79502]
- [`Error` is now implemented for `&T` where `T` implements `Error`.][75180]
- [`Poll::{map_ok, map_err}` are now implemented for
`Poll<Option<Result<T,E>>>`.][80968]
- [`unsigned_abs` is now implemented for all signed integer types.][80959]
- [`io::Empty` now implements `io::Seek`.][78044]
- [`rc::Weak<T>` and `sync::Weak<T>`'s methods such as `as_ptr`
are now implemented for `T: ?Sized` types.][80764]
- [`Div` and `Rem` by their `NonZero` variant is now implemented
for all unsigned integers.][79134]
Stabilized APIs
---------------
- [`Arc::decrement_strong_count`]
- [`Arc::increment_strong_count`]
- [`Once::call_once_force`]
- [`Peekable::next_if_eq`]
- [`Peekable::next_if`]
- [`Seek::stream_position`]
- [`array::IntoIter`]

- [`slice::strip_suffix`]
- [`str::split_inclusive`]
- [`sync::OnceState`]
- [`task::Wake`]
- [`VecDeque::range`]
- [`VecDeque::range_mut`]
Cargo
-----
- [Added the `split-debuginfo` profile option to control the -Csplit-debuginfo
codegen option.][cargo/9112]
- [Added the `resolver` field to `Cargo.toml` to enable the new
feature resolver and CLI option behavior.][cargo/8997] Version
2 of the feature resolver will try to avoid unifying features of
dependencies where that unification could be unwanted. Such as
using the same dependency with a `std` feature in a build scripts
and proc-macros, while using the `no-std` feature in the final
binary. See the [Cargo book documentation][feature-resolver@2.0]
for more information on the feature.
Rustdoc
-------
- [Rustdoc will now include documentation for methods available
from _nested_ `Deref` traits.][80653]
- [You can now provide a `--default-theme` flag which sets the
default theme to use for documentation.][79642]
Various improvements to intra-doc links:
- [You can link to non-path primitives such as `slice`.][80181]
- [You can link to associated items.][74489]
- [You can now include generic parameters when linking to items,
like `Vec<T>`.][76934]
Misc
----
- [You can now pass `--include-ignored` to tests (e.g. with
`cargo test -- --include-ignored`) to include testing tests marked
`#[ignore]`.][80053]
Compatibility Notes
-------------------
- [WASI platforms no longer use the `wasm-bindgen` ABI, and instead
use the wasm32 ABI.][79998]
- [`rustc` no longer promotes division, modulo and indexing operations
to `const` that could fail.][80579]
- [The minimum version of glibc for the following platforms has
been bumped to version 2.31 for the distributed artifacts.][81521]
- `armv5te-unknown-linux-gnueabi`
- `sparc64-unknown-linux-gnu`
- `thumbv7neon-unknown-linux-gnueabihf`
- `armv7-unknown-linux-gnueabi`
- `x86_64-unknown-linux-gnux32`
- [`atomic::spin_loop_hint` has been deprecated.][80966] It's
recommended to use `hint::spin_loop` instead.
Internal Only

Note to self: run pkglint before committing.
Thanks to jperkin@ for the note.

This appears to no longer be needed.
I could swear I had done a successful re-build before the previous commit,
so not sure how that happened.
Build fix, so no revision bump.

Pkgsrc changes:
* Adjust patches, re-compute line offsets, fix capitalization.
* Remove i686/FreeBSD support, no longer provided upstream.
* Bump bootstraps to 1.49.0.
* Change USE_TOOLS from bsdtar to gtar.
* Reduce diffs to pkgsrc-wip package patches.
* Allow rust.BUILD_TARGET to override automatic choice of target.
* Add an i586/NetBSD (pentium) bootstrap variant (needs testing),
not yet added as bootstrap since 1.49 doesn't have that variant.
Upstream changes:
Version 1.50.0 (2021-02-11)
============================
Language
-----------------------
- [You can now use `const` values for `x` in `[x; N]` array
expressions.][79270] This has been technically possible since
1.38.0, as it was unintentionally stabilized.
- [Assignments to `ManuallyDrop<T>` union fields are now considered
safe.][78068]
Compiler
-----------------------
- [Added tier 3\* support for the `armv5te-unknown-linux-uclibceabi`
target.][78142]
- [Added tier 3 support for the `aarch64-apple-ios-macabi` target.][77484]
- [The `x86_64-unknown-freebsd` is now built with the full toolset.][79484]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
-----------------------
- [`proc_macro::Punct` now implements `PartialEq<char>`.][78636]
- [`ops::{Index, IndexMut}` are now implemented for fixed sized
arrays of any length.][74989]
- [On Unix platforms, the `std::fs::File` type now has a "niche"
of `-1`.][74699] This value cannot be a valid file descriptor,
and now means `Option<File>` takes up the same amount of space
as `File`.
Stabilized APIs
---------------
- [`bool::then`]
- [`btree_map::Entry::or_insert_with_key`]
- [`f32::clamp`]
- [`f64::clamp`]
- [`hash_map::Entry::or_insert_with_key`]
- [`Ord::clamp`]
- [`RefCell::take`]
- [`slice::fill`]
- [`UnsafeCell::get_mut`]
The following previously stable methods are now `const`.
- [`IpAddr::is_ipv4`]
- [`IpAddr::is_ipv6`]
- [`Layout::size`]
- [`Layout::align`]
- [`Layout::from_size_align`]
- `pow` for all integer types.
- `checked_pow` for all integer types.
- `saturating_pow` for all integer types.
- `wrapping_pow` for all integer types.
- `next_power_of_two` for all unsigned integer types.
- `checked_power_of_two` for all unsigned integer types.
Cargo
-----------------------
- [Added the `[build.rustc-workspace-wrapper]` option.][cargo/8976]
This option sets a wrapper to execute instead of `rustc`, for
workspace members only.
- [`cargo:rerun-if-changed` will now, if provided a directory, scan the entire
contents of that directory for changes.][cargo/8973]
- [Added the `--workspace` flag to the `cargo update` command.][cargo/8725]
Misc
----
- [The search results tab and the help button are focusable with
keyboard in rustdoc.][79896]
- [Running tests will now print the total time taken to execute.][75752]
Compatibility Notes
-------------------
- [The `compare_and_swap` method on atomics has been deprecated.][79261]
It's recommended to use the `compare_exchange` and
`compare_exchange_weak` methods instead.
- [Changes in how `TokenStream`s are checked have fixed some cases
where you could write unhygenic `macro_rules!` macros.][79472]
- [`#![test]` as an inner attribute is now considered unstable like
other inner macro attributes, and reports an error by default
through the `soft_unstable` lint.][79003]
- [Overriding a `forbid` lint at the same level that it was set is
now a hard error.][78864]
- [Dropped support for all cloudabi targets.][78439]
- [You can no longer intercept `panic!` calls by supplying your
own macro.][78343] It's recommended to use the `#[panic_handler]`
attribute to provide your own implementation.
- [Semi-colons after item statements (e.g. `struct Foo {};`) now
produce a warning.][78296]

The current i386 bootstrap is built for NetBSD 8.x, and so is linked
against libstdc++.so.8. NetBSD 9.x still requires compat80 for it to
run.
This isn't a complete workaround, as builds still fail in a sandboxed
environment that doesn't have compat80 installed outside it. Dealing
with that would require another workaround somewhat like the one used
for ghc*, but a little different.
|
|
|
|
in options.mk, nia@ pointed out.
|
|
This is because in that case we're not using the rust-internal
copies of those libraries, governed by the rust-cargo-static option.
|
|
|
|
Key off BUILD_TARGET instead of whether we're cross-building,
as bootstrap kits *can* be built natively (yes, the former state
was my suggestion, but on second thought this is more correct).
|
|
|
|
The 1.49 cargo binary has a much reduced set of dynamic dependencies,
increasing the probability that they'll run on the host.
|
|
The final compiler will be dynamically linked with OpenSSL and curl,
but this is undesirable in the case of bootstraps where it might be
built against a version incompatible with version the user has.
Discussed with he@.
|
|
Havard would like all rusts to be built with rust-cargo-static,
because this makes it easier to produce working bootstaps.
In order to do this, we need to handle the OpenSSL and curl
dependencies in older bootstrap kits properly.
This means, for the remaining bootstraps that do not yet have
cargo with static/vendored dependencies:
- depend on base 8.0 openssl (compat80) on i386.
- depend on pkgsrc curl on aarch64 and earmv7.
the armv7 bootstrap is built for 9.0 so does not need compat80.
the aarch64 bootstrap is built for 8.99.50 so does not need compat80.
|
|
This reduces the external dynamic dependencies, because this
bootstrap kit is built with the --enable-cargo-native-static
option, and is verified to fix the build for martin@
|
|
|
|
This should be a temporary measure until all the bootstraps are fixed

Pkgsrc changes:
* Adjust patches, convert tabs to spaces so that tests pass.
* Remove patches which are no longer needed (upstream changed)
* Minor adjustments for SunOS, e.g. disable stack probes.
* Adjust cargo checksum patching accordingly.
* Remove commented-out use of PATCHELF on NetBSD, which doesn't work anyway...
Upstream changes:
Version 1.49.0 (2020-12-31)
============================
Language
-----------------------
- [Unions can now implement `Drop`, and you can now have a field in a union
with `ManuallyDrop<T>`.][77547]
- [You can now cast uninhabited enums to integers.][76199]
- [You can now bind by reference and by move in patterns.][76119] This
allows you to selectively borrow individual components of a type. E.g.
```rust
#[derive(Debug)]
struct Person {
name: String,
age: u8,
}
let person = Person {
name: String::from("Alice"),
age: 20,
};
// `name` is moved out of person, but `age` is referenced.
let Person { name, ref age } = person;
println!("{} {}", name, age);
```
Compiler
-----------------------
- [Added tier 1\* support for `aarch64-unknown-linux-gnu`.][78228]
- [Added tier 2 support for `aarch64-apple-darwin`.][75991]
- [Added tier 2 support for `aarch64-pc-windows-msvc`.][75914]
- [Added tier 3 support for `mipsel-unknown-none`.][78676]
- [Raised the minimum supported LLVM version to LLVM 9.][78848]
- [Output from threads spawned in tests is now captured.][78227]
- [Change os and vendor values to "none" and "unknown" for some targets][78951]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
-----------------------
- [`RangeInclusive` now checks for exhaustion when calling `contains`
and indexing.][78109]
- [`ToString::to_string` now no longer shrinks the internal buffer
in the default implementation.][77997]
- [`ops::{Index, IndexMut}` are now implemented for fixed sized
arrays of any length.][74989]
Stabilized APIs
---------------
- [`slice::select_nth_unstable`]
- [`slice::select_nth_unstable_by`]
- [`slice::select_nth_unstable_by_key`]
The following previously stable methods are now `const`.
- [`Poll::is_ready`]
- [`Poll::is_pending`]
Cargo
-----------------------
- [Building a crate with `cargo-package` should now be independently
reproducible.][cargo/8864]
- [`cargo-tree` now marks proc-macro crates.][cargo/8765]
- [Added `CARGO_PRIMARY_PACKAGE` build-time environment
variable.] [cargo/8758] This variable will be set if the crate
being built is one the user selected to build, either with `-p`
or through defaults.
- [You can now use glob patterns when specifying packages &
targets.][cargo/8752]
Compatibility Notes
-------------------
- [Demoted `i686-unknown-freebsd` from host tier 2 to target tier
2 support.][78746]
- [Macros that end with a semi-colon are now treated as statements
even if they expand to nothing.][78376]
- [Rustc will now check for the validity of some built-in attributes
on enum variants.][77015] Previously such invalid or unused
attributes could be ignored.
- Leading whitespace is stripped more uniformly in documentation
comments, which may change behavior. You read [this post about
the changes][rustdoc-ws-post] for more details.
- [Trait bounds are no longer inferred for associated types.][79904]
Internal Only
-------------
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.
- [rustc's internal crates are now compiled using the `initial-exec` Thread
Local Storage model.][78201]
- [Calculate visibilities once in resolve.][78077]
- [Added `system` to the `llvm-libunwind` bootstrap config option.][77703]
- [Added `--color` for configuring terminal color support to bootstrap.][79004]

Other OS bundle the necessary libraries with the bootstrap kits, and enabling
this option would mean having to carry additional patches for the bundled zlib
etc.
|
|
|
|
|
|
* Remove a few commented-out entries/settings
* Add @PREFIX@ substitution to the netbsd_base.rs patch,
and adjust patch accordingly.
|
|
bootstrap is built for NetBSD-9.*.
|
|
Switch over to the illumos target and update to the latest, 1.46.0 is too old
to build 1.48.0.
|
|
|
|
|
|
Pkgsrc changes:
* Compensate for files being moved around upstream.
* Introduce optional, on-by-default semi-static building of cargo,
using the internal curl and openssl sources. This reduces the dynamic
dependencies of cargo and therefore the rust package itself.
Ref. options.mk.
* The 1.47.0 bootstrap kits have been re-built with the above option
turned on, so no longer depends on curl or openssl from pkgsrc and/or
from earlier OS or pkgsrc versions. This should hopefully fix
installation of rust with non-default PREFIX, ref. PR#54453.
Upstream changes:
Version 1.48.0 (2020-11-19)
==========================
Language
--------
- [The `unsafe` keyword is now syntactically permitted on modules.][75857] This
is still rejected *semantically*, but can now be parsed by procedural macros.
Compiler
--------
- [Stabilised the `-C link-self-contained=<yes|no>` compiler flag.][76158]
This tells `rustc` whether to link its own C runtime and libraries
or to rely on a external linker to find them. (Supported only on
`windows-gnu`, `linux-musl`, and `wasi` platforms.)
- [You can now use `-C target-feature=+crt-static` on `linux-gnu` targets.]
[77386]
Note: If you're using cargo you must explicitly pass the `--target` flag.
- [Added tier 2\* support for `aarch64-unknown-linux-musl`.][76420]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`io::Write` is now implemented for `&ChildStdin` `&Sink`, `&Stdout`,
and `&Stderr`.][76275]
- [All arrays of any length now implement `TryFrom<Vec<T>>`.][76310]
- [The `matches!` macro now supports having a trailing comma.][74880]
- [`Vec<A>` now implements `PartialEq<[B]>` where `A: PartialEq<B>`.][74194]
- [The `RefCell::{replace, replace_with, clone}` methods now all use
`#[track_caller]`.][77055]
Stabilized APIs
---------------
- [`slice::as_ptr_range`]
- [`slice::as_mut_ptr_range`]
- [`VecDeque::make_contiguous`]
- [`future::pending`]
- [`future::ready`]
The following previously stable methods are now `const fn`'s:
- [`Option::is_some`]
- [`Option::is_none`]
- [`Option::as_ref`]
- [`Result::is_ok`]
- [`Result::is_err`]
- [`Result::as_ref`]
- [`Ordering::reverse`]
- [`Ordering::then`]
Cargo
-----
Rustdoc
-------
- [You can now link to items in `rustdoc` using the intra-doc link
syntax.][74430] E.g. ``/// Uses [`std::future`]`` will automatically generate
a link to `std::future`'s documentation. See ["Linking to items by
name"][intradoc-links] for more information.
- [You can now specify `#[doc(alias = "<alias>")]` on items to add
search aliases when searching through `rustdoc`'s UI.][75740]
Compatibility Notes
-------------------
- [Promotion of references to `'static` lifetime inside `const fn`
now follows the same rules as inside a `fn` body.][75502] In
particular, `&foo()` will not be promoted to `'static` lifetime
any more inside `const fn`s.
- [Associated type bindings on trait objects are now verified to meet the bounds
declared on the trait when checking that they implement the trait.][27675]
- [When trait bounds on associated types or opaque types are ambiguous, the
compiler no longer makes an arbitrary choice on which bound to use.][54121]
- [Fixed recursive nonterminals not being expanded in macros during
pretty-print/reparse check.][77153] This may cause errors if your macro wasn't
correctly handling recursive nonterminal tokens.
- [`&mut` references to non zero-sized types are no longer promoted.][75585]
- [`rustc` will now warn if you use attributes like `#[link_name]` or `#[cold]`
in places where they have no effect.][73461]
- [Updated `_mm256_extract_epi8` and `_mm256_extract_epi16` signatures in
`arch::{x86, x86_64}` to return `i32` to match the vendor signatures.][73166]
- [`mem::uninitialized` will now panic if any inner types inside
a struct or enum disallow zero-initialization.][71274]
- [`#[target_feature]` will now error if used in a place where it
has no effect.][78143]
- [Foreign exceptions are now caught by `catch_unwind` and will
cause an abort.][70212] Note: This behaviour is not guaranteed
and is still considered undefined behaviour, see the [`catch_unwind`]
documentation for further information.
Internal Only
-------------
These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.
- [Building `rustc` from source now uses `ninja` by default over `make`.][74922]
You can continue building with `make` by setting `ninja=false` in
your `config.toml`.
- [cg_llvm: `fewer_names` in `uncached_llvm_type`][76030]
- [Made `ensure_sufficient_stack()` non-generic][76680]

This is for the benefit of NetBSD/powerpc, where we now depends on
the recently added libatomic-links package which leaves symlinks to
the libatomic library files in that directory. This is so that we
don't automatically pick up other libraries behind the compiler users
back.
Also, match the newly uploaded NetBSD/macppc 9.0 bootstrap (regenerated
with this patch applied to 1.46.0).
No pkgrevision bump, since this is a build fix for NetBSD/powerpc.
|
|
|
|
so now we need -latomic on powerpc.
