* cranelift: Add extra runtests for `clz`/`ctz` * riscv64: Restrict lowering rules for `ctz`/`clz` * cranelift: Add `u64` isle helpers * riscv64: Improve `ctz` codegen * riscv64: Improve `clz` codegen * riscv64: Improve `cls` codegen * riscv64: Improve `clz.i128` codegen Instead of checking if we have 64 zeros in the top half. Check if it *is* 0, that way we avoid loading the `64` constant. * riscv64: Improve `ctz.i128` codegen Instead of checking if we have 64 zeros in the bottom half. Check if it *is* 0, that way we avoid loading the `64` constant. * riscv64: Use extended value in `lower_cls` * riscv64: Use pattern matches on `bseti`
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
