ICE: feat(generic_const_exprs) + debug assertions

[matthiaskrgr]

Code

Needs rust built with debug assertions!

const L: usize = 4;

pub trait Print<const N: usize> {
    fn print(&self) -> usize {
        N
    }
}

pub struct Printer;
impl Print<L> for Printer {}

fn main() {
    let p = Printer;
    assert_eq!(p.print(), 4);
}

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.67.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -Z crate-attr=feature(generic_const_exprs) -Z unstable-options

query stack during panic:
#0 [codegen_select_candidate] computing candidate for `<Printer as Print<L>>`
#1 [resolve_instance] resolving instance `<Printer as Print<L>>::print`
#2 [analysis] running analysis passes on this crate
end of query stack

another example:

#![crate_type = "lib"]
#![feature(portable_simd)]

use std::simd::Simd;
const N: usize = 8;

#[no_mangle]
// CHECK-LABEL: @wider_reduce_into_iter
pub fn wider_reduce_into_iter(x: Simd<u8, N>) -> u16 {
    // CHECK: zext <8 x i8>

    // CHECK: call i16 @llvm.vector.reduce.add.v8i16(<8 x i16>
    x.to_array().into_iter().map(u16::from).sum()
}

[matthiaskrgr]

another one

// run-pass
#![allow(dead_code)]

fn foo<T>(t: T) -> impl Into<[T; { const FOO: usize = 1; FOO }]> {
    [t]
}

fn bar() -> impl Into<[u8; { const FOO: usize = 1; FOO }]> {
    [99]
}

fn main() {
    println!("{:?}", foo(42).into());
    println!("{:?}", bar().into());
}

[matthiaskrgr]

None of these seem to crash anymore, probably fixed by #105561 🎉

[albertlarsan68]

Which example should I choose to add as a regression test ?

[albertlarsan68]

@rustbot claim

Also put this in my to-do list.

[albertlarsan68]

@rustbot release-assignment

I think the tests were already added in the PR.
