Rust target-cpu=native gets slower SIMD execution

pip install fastapi[all] is failing due to a rust component?

Rust target-cpu=native gets slower SIMD execution

I'm making a simple test of the Rust wrappers for x86 intrinsics: the approximation of PI by the Leibniz series:

My guess is that you're hitting this bug: https://github.com/rust-lang/rust/issues/83027

The bug is that when native is used, target_feature isn't applied correctly, which is what all of the intrinsics use. As a result, your calls to the intrinsic functions probably aren't being inlined. You should look at a profile to confirm that.

More generally, I would recommend using runtime CPU feature detection and correct use of #[target_feature]. You should only be calling functions that operate on 32-byte vectors from functions that have at least the avx feature enabled.

The problem is quite clear:

Your Rust target architecture (64-bit) does not match your python interpreter (32-bit)

Either upgrade your Python interpreter to 64 bit, or use rustup to install a 32 bit Rust target

Edit: Here is how you could manually target 32 bit on a x86_64 machine
