Mojo function

permlane_swap

def permlane_swap[dtype: DType, //, stride: Int](val1: Scalar[dtype], val2: Scalar[dtype]) -> SIMD[dtype, 2]

Swaps values between lanes using AMD permlane swap instruction.

Parameters:

• ​dtype (DType): Data type of the values (must be 32-bit type).
• ​stride (Int): Swap stride (must be 16 or 32).

Args:

• ​val1 (Scalar[dtype]): First value to swap.
• ​val2 (Scalar[dtype]): Second value to swap.

Returns:

SIMD[dtype, 2]: SIMD vector containing the swapped values.
