Description
I have some code using ndarray dot products, which in turn calls matrixmultiply::sgemm or dgemm, and these trap when built with cranelift. Here's a reproducer:
cargo-features = ["codegen-backend"]
[package]
name = "dot"
edition = "2021"
[dependencies]
ndarray = "0.15.6"
[profile.dev]
codegen-backend = "cranelift"#[test]
fn dot_f32() {
let matrix = ndarray::Array2::<f32>::eye(10);
let _ = matrix.dot(&matrix);
}
#[test]
fn dot_f64() {
let matrix = ndarray::Array2::<f64>::eye(10);
let _ = matrix.dot(&matrix);
}$ cargo test
...
running 2 tests
