This should probably update the platform support docs to indicate the tier 2 target. |
☔ The latest upstream changes (presumably #122170) made this pull request unmergeable. Please resolve the merge conflicts. |
@Amanieu this needs a manual rebase and push I guess |

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) <a id="1.82.0-Internal-Changes"></a> ## 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](rust-lang/rust#127513) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

Musl Patch ========== riscv64gc-unknown-linux-musl gets promoted to tier 2 and `crt_static_default` is updated to false in rust-lang/rust#122049, which triggers rust-lang/rust#82521 (comment) when building stage2 library artifacts (riscv64gc-unknown-linux-gnu -> riscv64gc-unknown-linux-musl). I patched it to re-enable `crt_static_default` for `riscv64gc-unknown-linux-musl` to fix the build and align with the behavior on x86 Arch Linux, where `rust-musl` defaults to statically link musl. Wasm compiler_builtins bug ========================== Wasm compiler_builtins rlib from built `rust-wasm` package includes objects for host architecture(riscv64 in our case, and x86_64 for x86 Arch Linux). This is not reproducible for toolchains installed via rustup so I have reported it to Arch Linux: https://gitlab.archlinux.org/archlinux/packaging/packages/rust/-/issues/3 Complications when building 1.82.0 ================================== rust-lang/rust#125016 landed in 1.82.0, which breaks building rust 1.82.0 using our packaged rust 1.81.0. Compiling the new compiler_builtins component requires a rustc compiler that includes rust-lang/rust@99e6a28 but unfortunately 1.81.0 does not, leading to the following ICE: https://archriscv.felixc.at/.status/log.htm?url=logs/rust/rust-1:1.82.0-1.log internal compiler error: compiler/rustc_codegen_llvm/src/abi.rs:126:22: unsupported float: Reg { kind: Float, size: Size(2 bytes) } This is mitigated upstream by bumping stage0 to 1.82: rust-lang/rust#129268 (comment) So we need to first build 1.82.0 rustc once without the f16/f128 handling part in compiler_builtins, to get a compiler that is capable of handling f16/f128. And then we can use this compiler to compile compiler_builtins with f16/f128 handling. It's not easy to do so in one patch. The most easy way is to build and package rust 1.82.0 twice. This PR covers the first part and disable-f16-f128.diff will be removed in the second part.

This is not reproducible for toolchains installed via rustup so I have reported it to Arch Linux: https://gitlab.archlinux.org/archlinux/packaging/packages/rust/-/issues/3 Complications when building 1.82.0 ================================== rust-lang/rust#125016 landed in 1.82.0, which breaks building rust 1.82.0 using our packaged rust 1.81.0. Compiling the new compiler_builtins component requires a rustc compiler that includes rust-lang/rust@99e6a28 but unfortunately 1.81.0 does not, leading to the following ICE: https://archriscv.felixc.at/.status/log.htm?url=logs/rust/rust-1:1.82.0-1.log internal compiler error: compiler/rustc_codegen_llvm/src/abi.rs:126:22: unsupported float: Reg { kind: Float, size: Size(2 bytes) } This is mitigated upstream by bumping stage0 to 1.82: rust-lang/rust#129268 (comment) So we need to first build 1.82.0 rustc once without the f16/f128 handling part in compiler_builtins, to get a compiler that is capable of handling f16/f128. And then we can use this compiler to compile compiler_builtins with f16/f128 handling. It's not easy to do so in one patch. The most easy way is to build and package rust 1.82.0 twice. This PR covers the first part and disable-f16-f128.diff will be removed in the second part.

[feat: Add `info` cargo subcommand] (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] (rust-lang/rust#127513)
