Add x.sh and x.ps1 shell scripts by jyn514 · Pull Request #99992 · rust-lang/rust (original) (raw)

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 rust-lang/rust#104220 and rust-lang/rust#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)

Version 1.66.0 (2022-12-15)

Language

• Permit specifying explicit discriminants on all repr(Int) enums

  #[repr(u8)]
  enum Foo {
      A(u8) = 0,
      B(i8) = 1,
      C(bool) = 42,
  }

• Allow transmutes between the same type differing only in lifetimes
• Change constant evaluation errors from a deny-by-default lint to a hard error
• Trigger must_use on impl Trait for supertraits This makes impl ExactSizeIterator respect the existing #[must_use] annotation on Iterator.
• Allow ..X and ..=X in patterns
• Uplift clippy::for_loops_over_fallibles lint into rustc
• Stabilize sym operands in inline assembly
• Update to Unicode 15
• Opaque types no longer imply lifetime bounds This is a soundness fix which may break code that was erroneously relying on this behavior.

Compiler

• Add armv5te-none-eabi and thumbv5te-none-eabi tier 3 targets
  • Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.
• Add support for linking against macOS universal libraries

Libraries

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.

• Enable BOLT for LLVM compilation

New targets:

• [Add armv4t-none-eabi as a tier 3 target] (rust-lang/rust#100244)
• [Add powerpc64-unknown-openbsd and riscv64-unknown-openbsd as tier 3 targets] (rust-lang/rust#101025)
• Refer to Rust's [platform support page][platform-support-doc] for more information on Rust's tiered platform support.

Libraries

• [Don't generate PartialEq::ne in derive(PartialEq)] (rust-lang/rust#98655)
• [Windows RNG: Use BCRYPT_RNG_ALG_HANDLE by default] (rust-lang/rust#101325)
• [Forbid mixing System with direct system allocator calls] (rust-lang/rust#101394)
• [Document no support for writing to non-blocking stdio/stderr] (rust-lang/rust#101416)
• std::layout::Layout size must not overflow isize::MAX when rounded up to align 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)

• [<*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] (rust-lang/cargo#10807)
• [Do not add home bin path to PATH if it's already there] (rust-lang/cargo#11023)
• [Take priority into account within the pending queue] (rust-lang/cargo#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] (rust-lang/rust#95295). This also changes the safety conditions on Layout::from_size_align_unchecked.
• [PollFn now only implements Unpin if the closure is Unpin] (rust-lang/rust#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] (rust-lang/rust#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] (rust-lang/rust#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] (rust-lang/rust#99935)
• [Update the minimum external LLVM to 13] (rust-lang/rust#100460)
• [Don't duplicate file descriptors into stdio fds] (rust-lang/rust#101426)
• Sunset RLS
• [Deny usage of #![cfg_attr(..., crate_type = ...)] to set the crate type] (rust-lang/rust#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] (rust-lang/rust#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] (rust-lang/rust#99992)
• [compiletest: use target cfg instead of hard-coded tables] (rust-lang/rust#100260)
• [Use object instead of LLVM for reading bitcode from rlibs] (rust-lang/rust#98100)
• [Enable MIR inlining for optimized compilations] (rust-lang/rust#91743) This provides a 3-10% improvement in compiletimes for real world crates.
