@RalfJung RalfJung commented Aug 3, 2024

Part of #128288
Fixes #57241

The existing test tests/ui/consts/const_let_eq_float.rs (link) covers the basics, and also Miri has extensive tests covering the interpreter's float machinery. Also, that machinery can already be used on stable inside const/static initializers, just not inside const fn.

This was explicitly called out in rust-lang/rfcs#3514 so in a sense t-lang just recently already FCP'd this, but let's hear from them whether they want another FCP for the stabilization here or whether that was covered by the FCP for the RFC.

I removed this test since it seems fully covered by the min_const_fn tests.

Thanks @RalfJung. This looks consistent with what we adopted in RFC 3514. Let's go ahead with an expectedly quick and uneventful...

add back test for stable-const-can-only-call-stable-const

This got accidentally removed in rust-lang#128596 (file `tests/ui/internal/internal-unstable-const.rs`). The test has little to do with "allow internal unstable" though, so add it in a file that already tests various const stability things.

Also tweak the help that suggests to add `rustc_allow_const_fn_unstable` to make it clear that this needs team approval, since it is a fairly big gun.

stabilize const_float_bits_conv

This stabilizes `const_float_bits_conv`, and thus fixes rust-lang#72447. With rust-lang#128596 having landed, this is entirely a libs-only question now.

```rust

    pub const fn from_bits(v: u32) -> Self;
    pub const fn to_be_bytes(self) -> [u8; 4];

    pub const fn to_ne_bytes(self) -> [u8; 4];

    pub const fn from_le_bytes(bytes: [u8; 4]) -> Self;
    pub const fn from_ne_bytes(bytes: [u8; 4]) -> Self;
}

<a id="1.82.0-Cargo"></a>

## Cargo

-   [feat: Add `info` cargo subcommand](rust-lang/cargo#14141)

<a id="1.82.0-Compatibility-Notes"></a>

## Compatibility Notes

-   We now [disallow setting some built-in cfgs via the command-line](rust-lang/rust#126158) with the newly added [`explicit_builtin_cfgs_in_flags`](https://doc.rust-lang.org/rustc/lints/listing/deny-by-default.html#explicit-builtin-cfgs-in-flags) lint in order to prevent incoherent state, eg. `windows` cfg active but target is Linux based. The appropriate [`rustc` flag](https://doc.rust-lang.org/rustc/command-line-arguments.html) should be used instead.
-   The standard library has a new implementation of `binary_search` which is significantly improves performance ([#&#8203;128254](rust-lang/rust#128254)). However when a sorted slice has multiple values which compare equal, the new implementation may select a different value among the equal ones than the old implementation.
-   [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to sockets](rust-lang/rust#128259). This avoids killing the process with SIGPIPE when writing to a closed socket, which matches the existing behavior on other UNIX targets.
-   [Removes a problematic hack that always passed the --whole-archive linker flag for tests, which may cause linker errors for code accidentally relying on it.](rust-lang/rust#128400)
-   The WebAssembly target features `multivalue` and `reference-types` are now
    both enabled by default. These two features both have subtle changes implied
    for generated WebAssembly binaries. For the `multivalue` feature, WebAssembly
    target support has changed when upgrading to LLVM 19. Support for generating
    functions with multiple returns no longer works and
    `-Ctarget-feature=+multivalue` has a different meaning than it did in LLVM 18
    and prior. There is no longer any supported means to generate a module that has
    a function with multiple returns in WebAssembly from Rust source code. For the
    `reference-types` feature the encoding of immediates in the `call_indirect`, a
    commonly used instruction by the WebAssembly backend, has changed. Validators
    and parsers which don't understand the `reference-types` proposal will no
    longer accept modules produced by LLVM due to this change in encoding of
    immediates. Additionally these features being enabled are encoded in the
    `target_features` custom section and may affect downstream tooling such as
    `wasm-opt` consuming the module. Generating a WebAssembly module that disables
    default features requires `-Zbuild-std` support from Cargo and more information
    can be found at
    [rust-lang/rust#128511](rust-lang/rust#128511).

## 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.

wip-sync pushed a commit to NetBSD/pkgsrc-wip that referenced this pull request Oct 27, 2024
Pkgsrc changes:
 * Adapt patches, apply to new vendored crates where needed.
 * Back-port rust pull request 130110, "make dist vendoring configurable"
 * Disable "dist vendoring", otherwise cargo would try to access
   the network during the build phase.

Cargo

  (rust-lang/cargo#14141)

Compatibility Notes
-------------------
 - We now [disallow setting some built-in cfgs via the
   command-line](rust-lang/rust#126158) with
   the newly added
   [`explicit_builtin_cfgs_in_flags`]
   (https://doc.rust-lang.org/rustc/lints/listing/deny-by-default.html#explicit-builtin-cfgs-in-flags)
   lint in order to prevent incoherent state, eg. `windows` cfg active
   but target is Linux based. The appropriate [`rustc` flag]
   (https://doc.rust-lang.org/rustc/command-line-arguments.html)
   should be used instead.

- The standard library has a new implementation of `binary_search`
  which is significantly improves performance
  ([#128254](rust-lang/rust#128254)). However
  when a sorted slice has multiple values which compare equal, the
  new implementation may select a different value among the equal
  ones than the old implementation.

- [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to
  sockets](rust-lang/rust#128259). This avoids
  killing the process with SIGPIPE when writing to a closed socket,
  which matches the existing behavior on other UNIX targets.

- [Removes a problematic hack that always passed the --whole-archive
  linker flag for tests, which may cause linker errors for code
  accidentally relying on it.]
  (rust-lang/rust#128400)

- The WebAssembly target features `multivalue` and `reference-types`
  are now both enabled by default. These two features both have
  subtle changes implied for generated WebAssembly binaries. For
  the `multivalue` feature, WebAssembly target support has changed
  when upgrading to LLVM 19. Support for generating functions with
  multiple returns no longer works and `-Ctarget-feature=+multivalue`
  has a different meaning than it did in LLVM 18 and prior. There
  is no longer any supported means to generate a module that has
  a function with multiple returns in WebAssembly from Rust source
  code. For the `reference-types` feature the encoding of immediates
  in the `call_indirect`, a commonly used instruction by the
  WebAssembly backend, has changed. Validators and parsers which
  don't understand the `reference-types` proposal will no longer
  accept modules produced by LLVM due to this change in encoding
  of immediates. Additionally these features being enabled are
  encoded in the `target_features` custom section and may affect
  downstream tooling such as `wasm-opt` consuming the module.
  Generating a WebAssembly module that disables default features
  requires `-Zbuild-std` support from Cargo and more information
  can be found at
  [rust-lang/rust#128511](rust-lang/rust#128511).
- [Rust now raises unsafety errors for union patterns in parameter-position]
  (rust-lang/rust#130531)

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.

- [Update to LLVM 19]
