Cranelift based backend for rustc
👋 Hey, It looks like cg_clif works on s390x! 🎉 Thanks @uweigand! Should we add a qemu runner on CI to prevent regressions? (We probably need to wait for cranelift...
Trying to run the cranelift testsuite on an x86_64 macOS system with Xcode 15 results in an error that looks roughly like this: ``` = note: ld: warning: search path...
Reproduction is in Custom MIR. Not sure if this can be triggered from surface rust ```rust #![feature(custom_mir, core_intrinsics)] extern crate core; use core::intrinsics::mir::*; #[custom_mir(dialect = "runtime", phase = "initial")] pub...

Setting up the tool like in the Readme, I am getting this error when running it as `cargo clif build`: ``` error: failed to run `rustc` to learn about target-specific...
