//! This example is mean to be used for inspecting the generated assembly.
//! This can be interesting when working with simd intrinsics.
//!
//! To use:
//! - Mark the function that should be investigated with `#[inline(never)]`.
//! - If needed, add any required feature to the function, for example `#[target_feature(enable = "sse4.1")]`
//! - Change the code below to use the changed function.
//! Currently it is set up to look at the f32 version of the SSE 4-point butterfly.
//! It uses the FftPlannerSse to plan a length 4 FFT, that will use the modified butterfly.
//! - Ask rustc to output assembly code:
//! `cargo rustc --release --features sse --example asmtest -- --emit=asm`
//! - This will create a file at `target/release/examples/asmtest-0123456789abcdef.s` (with a random number in the filename).
//! - Open this file and search for the function.
use rustfft::num_complex::Complex32;
//use rustfft::num_complex::Complex64;
//use rustfft::FftPlannerScalar;
use rustfft::FftPlannerSse;
//use rustfft::FftPlannerNeon;
fn main() {
//let mut planner = FftPlannerScalar::new();
let mut planner = FftPlannerSse::new().unwrap();
//let mut planner = FftPlannerNeon::new().unwrap();
let fft = planner.plan_fft_forward(4);
let mut buffer = vec![Complex32::new(0.0, 0.0); 100];
fft.process(&mut buffer);
