Promote powerpc64le-unknown-linux-musl to tier 2 with host tools #133801

Gelbpunkt · 2024-12-03T15:53:21Z

I'm using crosstool-ng for building a toolchain because GCC 9 from musl-toolchain.sh has float ABI issues (?) and can't compile LLVM, and writing a crosstool-ng config for a target feels less hacky than yet another target specific shell script. I also defined a kernel version, since there wasn't one specified before. If a lower version is desired, just let me know. I also tried to match the rust configure args with the loongarch64 musl tier 2 target.

The resulting compiler works fine, built with DEPLOY=1 ./src/ci/docker/run.sh dist-powerpc64le-linux and tested on Alpine Linux in a VM and on a bare metal POWER8 machine:

[Stabilize higher precedence trailing flags](rust-lang/cargo#14900) - [Pass `CARGO_CFG_FEATURE` to build scripts](rust-lang/cargo#14902) <a id="1.85.0-Rustdoc"></a> ## Rustdoc - [Doc comment on impl blocks shows the first line, even when the impl block is collapsed](rust-lang/rust#132155) <a id="1.85.0-Compatibility-Notes"></a> ## Compatibility Notes - [`rustc` no longer treats the `test` cfg as a well known check-cfg](rust-lang/rust#131729), instead it is up to the build systems and users of `--check-cfg`\[^check-cfg] to set it as a well known cfg using `--check-cfg=cfg(test)`. This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests. [Cargo (for now) unconditionally sets the `test` cfg as a well known cfg](rust-lang/cargo#14963). \[^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html - [Disable potentially incorrect type inference if there are trivial and non-trivial where-clauses](rust-lang/rust#132325) - `std::env::home_dir()` has been deprecated for years, because it can give surprising results in some Windows configurations if the `HOME` environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function. - [Make `core::ffi::c_char` signedness more closely match that of the platform-default `char`](rust-lang/rust#132975) This changed `c_char` from an `i8` to `u8` or vice versa on many Tier 2 and 3 targets (mostly Arm and RISC-V embedded targets). The new definition may result in compilation failures but fixes compatibility issues with C. The `libc` crate matches this change as of its 0.2.169 release. - [When compiling a nested `macro_rules` macro from an external crate, the content of the inner `macro_rules` is now built with the edition of the external crate, not the local crate.](rust-lang/rust#133274) - [Increase `sparcv9-sun-solaris` and `x86_64-pc-solaris` Solaris baseline to 11.4.](rust-lang/rust#133293) - [Show `abi_unsupported_vector_types` lint in future breakage reports](rust-lang/rust#133374) - [Error if multiple super-trait instantiations of `dyn Trait` need associated types to be specified but only one is provided](rust-lang/rust#133392) - [Change `powerpc64-ibm-aix` default `codemodel` to large](rust-lang/rust#133811) <a id="1.85.0-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. - [Build `x86_64-unknown-linux-gnu` with LTO for C/C++ code (e.g., `jemalloc`)](rust-lang/rust#134690) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
