error: 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 1.76.0-nightly (d5fab3376 2023-12-02) running on x86_64-unknown-linux-gnu

note: compiler flags: -Z codegen-backend=cranelift -Z dump-mir-dir=dir

warning: 2 warnings emitted

This is a Cranelift bug. It should propagate the error out into cg_clif, which would then give a rustc diagnostic for this. Cranelift doesn't support stack frames larger than 2GB. (Neither does LLVM, but LLVM tends to silently miscompile instead)

I can't reproduce this with the latest version in this repo.

Seems to be fixed, indeed.

Should be fixed on the next nightly then.

@bjorn3

@bjorn3 this is crashing again it seems.

Is it panicking with the same message?

Yeah, as if the original fix had been reverted or something :|

I can't reproduce this with rustc +nightly-2024-02-12 src/main.rs -Zcodegen-backend=cranelift where src/main.rs is:

#[repr(align(536870912))]

enum Aligned {
    Zero = 0,
    One = 1,
}

fn main() {
    let aligned = Aligned::Zero;

    assert_eq!(tou8(Aligned::Zero), 0);
}

fn tou8(al: Aligned) -> u8 {
    al as u8
}

weird.
for me:

rustc 1.78.0-nightly (1a648b397 2024-02-11)
binary: rustc
commit-hash: 1a648b397dedc98ada3dd3360f6d661ec2436c56

release: 1.78.0-nightly
Cranelift version: 0.104.0

so the only diff I can spot right now is that I'm on x86 and you're on aarch64, could that make a difference?

Edit: the backtrace also goes through some x86 stuff
/rust/deps/cranelift-codegen-0.104.0/src/isa/x64/abi.rs:957:46:

Of course. Will test on x86 in a bit.

On x86 cargo-bisect-rustc for me can't find any nightly for which it actually worked. Even manually checking a random nightly for which it should have worked (nightly-2023-12-31) it gives the same ICE. And with the latest version in this repo it fails too. Maybe I checked it on aarch64 back then too?

Probably the same issue:

auto-reduced (treereduce-rust):

//@compile-flags: --cap-lints=warn -Zcodegen-backend=cranelift
pub fn main() {
    let x = [1; 0x3f800000];
    let mut y = 0;
    for i in &x[..] {
        y += *i
    }
}

original:

//@ run-pass

pub fn main() {
    let x = [1; 0x3f800000];
    let mut y = 0;
    for i in &x[..] {
        y += *i
    }
    assert_eq!(y, 0xbf7fffff);
}
