afonso360 opened issue #5452:

:wave: Hey,

Fuzzgen found this when adding support for this instruction. This is very similar to #5199 but with select_spectre_guard instead of select.

.clif Test Case

test interpret
test run
set enable_llvm_abi_extensions=true
target x86_64

function %a(i128, i128, i128) -> i128 {
block0(v0: i128, v1: i128, v2: i128):
    v3 = select_spectre_guard.i128 v0, v1, v2
    return v3
}
; run: %a(1, 2, 3) == 2

Steps to Reproduce

Expected Results

The above tests to pass.

Actual Results
