+- [`std::arch::x86::_rdtsc` returns `u64` instead of `i64`][stdsimd/559]
+- [`std::arch::x86_64::_mm_shuffle_ps` takes an `i32` instead of `u32` for `mask`][stdsimd/522]
 - With the stabilisation of `mem::MaybeUninit`, `mem::uninitialized` use is no
   longer recommended, and will be deprecated in 1.38.0.
