Enum cranelift_codegen::isa::x64::args::RoundImm

pub enum RoundImm {
    RoundNearest,
    RoundDown,
    RoundUp,
    RoundZero,
}

Encode the rounding modes used as part of the Rounding Control field. Note, these rounding immediates only consider the rounding control field (i.e. the rounding mode) which only take up the first two bits when encoded. However the rounding immediate which this field helps make up, also includes bits 3 and 4 which define the rounding select and precision mask respectively. These two bits are not defined here and are implictly set to zero when encoded.

Variants

RoundNearest

Round to nearest mode.

RoundDown

Round down mode.

RoundUp

Round up mode.

RoundZero

Round to zero mode.
