👋 Hey,

We found this issue as part of a libcore test in cg_clif. (see: https://github.com/bjorn3/rustc_codegen_cranelift/issues/1256).

.clif Test Case

target aarch64

function %numcore(i128) -> b1 {
block0(v0: i128):
    v1 = iconst.i128 0
    v2 = icmp eq v0, v1
    return v2
}
; run: %numcore(36893488147419103231) == false
