Enum miri::shims::x86::FloatBinOp

source ·
enum FloatBinOp {
    Cmp {
        gt: bool,
        lt: bool,
        eq: bool,
        unord: bool,

Variants§

§

Cmp

Comparison

The semantics of this operator is a case distinction: we compare the two operands, and then we return one of the four booleans gt, lt, eq, unord depending on which class they fall into.

AVX supports all 16 combinations, SSE only a subset
