    v12 = call fn1(v11)
    v13 = iadd v9, v12
    return v13
}

Steps to Reproduce

  1. Run on an Apple M1 chip

Expected Results

Actual Results

The program paniced:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Error("unimplemented relocation addend Relocation { offset: 104, size: 26, kind: Relative, encoding: AArch64Call, symbol: SymbolId(3), addend: -4 }")', <some path>/.cargo/registry/src/github.com-1ecc6299db9ec823/cranelift-object-0.86.1/src/backend.rs:500:22

Versions and Environment

Cranelift version or commit: 0.86.1

Operating system: MacOS

Architecture: M1

Extra Info

This works for me on aarch64-unknown-gnu (see https://cirrus-ci.com/task/6079482023903232 - it runs a lot of additional things, but near the bottom of the "test" task it compiles the Fibonacci function fine), but not aarch64-apple-darwin

Thanks for the report. Did this CLIF come from Wasmtime or some other frontend? (I ask because we try to support Wasmtime's use of Cranelift on aarch64-apple-darwin but the use of Cranelift with other frontends is much less well-tested. That doesn't mean we don't want to support it, I'm just trying to judge the severity.) It sounds like we need to implement another relocation case here. If you're willing to dig into it further, I'd be happy to review a PR.

It came from a different frontend (a small compiler I'm writing). The problem seems to be withcranelift-object, because I can run the same program without error by using cranelift-jit (which I have adopted as a stopgap solution).

If you're willing to dig into it further, I'd be happy to review a PR.

I'd be happy to, but I'm not sure what a relocation is :)

I'd be happy to, but I'm not sure what a relocation is :)

I think this might already be fixed upstream in https://github.com/gimli-rs/object/pull/465, so it might be a case of just updating the object crate whenever they do their next release.

:wave: Hey,

Would you be able to test this code using PR #5434? It includes the updated version of object, and I suspect it might fix your issue.
