comptime members

FLOAT4_E2M1

Methods

__init__

def __init__(value: Int) -> Self

__eq__

def __eq__(self, other: Self) -> Bool

Returns:

Bool

simd_width

def simd_width(self) -> SIMDLength

Returns the operand fragment width, in bytes, this format expects.

FP6 holds only 24 payload bytes, but 24 is not a power of two, so it asks for 32. InstCombine narrows the operand back down, so the padding costs nothing. Stage FP6 loads as 24 bytes, not 32.

Returns:

SIMDLength: The fragment width in bytes.
