The LLVM intrinsic doesn't support float64x1_t, but the required instruction is a scalar form (e.g. `frint32x <Dd>, <Dn>`), so we can implement these using the scalar intrinsic. Note that Clang does not support these intrinsics, so they aren't covered by intrinsic-test. Additional validation is included in this patch to ensure that we're selecting an instruction with the same behaviour as the corresponding vector form (which all have intrinsic-tests).
stdarch - Rust's standard library SIMD components
Crates
This repository contains two main crates:
-
core_archimplementscore::arch- Rust's core library architecture-specific intrinsics, and -
std_detectimplementsstd::detect- Rust's standard library run-time CPU feature detection.
The std::simd component now lives in the
packed_simd_2 crate.
