2025-09-24std: add support for armv7a-vex-v5 targetTropical-0/+1
Co-authored-by: Lewis McClelland <lewis@lewismcclelland.me>
2025-04-27Use `feature(target_has_reliable_f16_f128)` in library testsTrevor Gross-110/+0
New compiler configuration has been introduced that is designed to replace the build script configuration `reliable_f16`, `reliable_f128`, `reliable_f16_math`, and `reliable_f128_math`. Do this replacement here, which allows us to clean up `std`'s build script. All tests are gated by `#[cfg(bootstrap)]` rather than doing a more complicated `cfg(bootstrap)` / `cfg(not(bootstrap))` split since the next beta split is within two weeks.
2025-04-02Revert "Disable `f16` on Aarch64 without `neon`"Trevor Gross-7/+0
The LLVM issue [1] was resolved and the fix was synced to rust-lang/rust in [2]. This reverts commit c51b229140c885cac757a405a328a07e90d5bca9. [1]: https://github.com/llvm/llvm-project/issues/129394 [2]: https://github.com/rust-lang/rust/pull/138695

2025-03-01Disable `f16` on Aarch64 without `neon`Trevor Gross-0/+7
LLVM has crashes at some `half` operations when built with assertions enabled if fp-armv8 is not available [1]. Things seem to usually work, but we are reaching LLVM undefined behavior so this needs to be disabled. [1]: https://github.com/llvm/llvm-project/issues/129394
2025-02-26Enable `f16` for LoongArchWANG Rui-1/+0
2025-02-20Enable `f16` for MIPSMartin Nordholts-1/+0
It seems as if `f16` works on MIPS now according to my testing on Rust master with LLVM 20, and I was asked to create PRs with my changes. I only tested on the flavour of `mipsel-unknown-linux-gnu` hardware that happens to be available to me, so I can't say anything about other MIPS hardware, but from a casual skimming of the LLVM code ([1], [2]) it seems like `f16` should work on all MIPS hardware. So enable it for all MIPS hardware. [1]: https://github.com/rust-lang/llvm-project/blob/rustc/20.1-2025-02-13/llvm/lib/Target/Mips/MipsISelLowering.h#L370 [2]: https://github.com/rust-lang/llvm-project/blob/rustc/20.1-2025-02-13/llvm/lib/CodeGen/TargetLoweringBase.cpp#L1367-L1388
2024-11-03Enable `f128` tests on all non-buggy platforms 🎉Trevor Gross-7/+12
With the `compiler-builtins` update to 0.1.137 [1], we now provide symbols necessary to work with `f128` everywhere. This means that we are no longer restricted to 64-bit linux, and can enable tests by default. There are still a handful of platforms that need to remain disabled because of bugs. This patch additionally disables the following: 1. MIPS [2] 2. 32-bit x86 [3] Math support is still off by default since those symbols are not yet available. [1]: https://github.com/rust-lang/rust/pull/132433 [2]: https://github.com/llvm/llvm-project/issues/96432 [3]: https://github.com/llvm/llvm-project/issues/77401
2024-10-05enable f16 and f128 on windows-gnullvm targetsMateusz Mikuła-2/+3
2024-09-30Enable `f16` tests on non-GNU WindowsTrevor Gross-3/+3
There is a MinGW ABI bug that prevents `f16` and `f128` from being usable on `windows-gnu` targets. This does not affect MSVC; however, we have `f16` and `f128` tests disabled on all Windows targets. Update the gating to only affect `windows-gnu`, which means `f16` tests will be enabled. There is no effect for `f128` since the default fallback is `false`.
2024-09-28Enable `f16` tests on x86 Apple platformsTrevor Gross-3/+0
These were disabled because Apple uses a special ABI for `f16`. `compiler-builtins` merged a fix for this in [1], which has since propagated to rust-lang/rust. Enable tests since there should be no remaining issues on these platforms. [1]: https://github.com/rust-lang/compiler-builtins/pull/675
2024-09-27Enable `f16` on platforms that were missing conversion symbolsTrevor Gross-14/+11
The only requirement for `f16` support, aside from LLVM not crashing and no ABI issues, is that symbols to convert to and from `f32` are available. Since the update to compiler-builtins in [1], we now provide these on all platforms. This also enables `f16` math since there are no further requirements. Still excluded are platforms for which LLVM emits infinitely-recursing code. [1]: https://github.com/rust-lang/rust/pull/125016

2024-08-23Enable `f16` tests on x86 and x86-64Trevor Gross-8/+8
Since the `compiler_builtins` update [1], ABI bugs on x86 should be resolved. Enable tests for f16 on these platforms now. `f16` math functions (`reliable_f16_math`) are still excluded because there is an LLVM crash for powi [2].

2024-08-01Add math functions for `f16` and `f128`Trevor Gross-0/+37
This adds missing functions for math operations on the new float types. Platform support is pretty spotty at this point, since even platforms with generally good support can be missing math functions. `std/build.rs` is updated to reflect this.

2024-07-03std: Set has_reliable_f16 to false for MIPS targets in build.rsMartin Nordholts-0/+2
To avoid this linker error: $ sudo apt install libc6-mips-cross gcc-mips-linux-gnu $ CC_mips_unknown_linux_gnu=mips-linux-gnu-gcc \ CARGO_TARGET_MIPS_UNKNOWN_LINUX_GNU_LINKER=mips-linux-gnu-gcc \ ./x test library/std --target mips-unknown-linux-gnu undefined reference to `__gnu_f2h_ieee' You get the same linker error also with mipsel, mips64 and mips64el toolchains.
2024-07-03library/std/build.rs: "powerpc64le" is not a target_archMartin Nordholts-1/+1
The target_arch of `powerpc64le` is `powerpc64`, so `powerpc64le` can be removed from a match arm in build.rs related to f16. You can check available `target_arch`:s with: $ rustc +nightly -Zunstable-options --print all-target-specs-json \ | grep powerpc | grep arch | sort | uniq "arch": "powerpc", "arch": "powerpc64",
2024-06-25Add build.rs config for reliable `f16` and `f128`Trevor Gross-0/+62
There are some complexities about what platforms we can test f16 and f128 on. Put this in build.rs so we have an easy way to configure tests with a single attribute, and keep it up to date.

2024-02-05Add support for custom JSON targets when using build-std.Lawrence Tang-35/+41
Currently, when building with `build-std`, some library build scripts check properties of the target by inspecting the target triple at `env::TARGET`, which is simply set to the filename of the JSON file when using JSON target files. This patch alters these build scripts to use `env::CARGO_CFG_*` to fetch target information instead, allowing JSON target files describing platforms without `restricted_std` to build correctly when using `-Z build-std`. Fixes wg-cargo-std-aware/#60.
