:wave: Hey,

While working in the fcmp testsuite for #4849 I discovered that all unordered float comparisons are unimplemented in AArch64.

I don't actually need this, its just a tracking issue.

.clif Test Case

test run
target aarch64

function %fcmp_uge_f32(f32, f32) -> b1 {
block0(v0: f32, v1: f32):
    v2 = fcmp uge v0, v1
    return v2
}
; run: %fcmp_uge_f32(0x0.5, 0x0.5) == true

A more comprehensive test suite was introduced in #4849

Steps to Reproduce

• clif-util test ./the-above.clif

Expected Results

The test to pass.

Actual Results

Crashes with unimplemented.

Versions and Environment

Cranelift version or commit: main
Operating system: Linux
Architecture: AArch64
