s8 elementwise squared difference of scalar and vector.

Parameters:

  • left_shift – [in] Common left shift applied to both inputs before requantization. Bound: the kernel evaluates (value + offset) << left_shift in int32; with full-range int8 inputs and zero-points the widest operand is 255, so left_shift is at most 23. The scale 1 << left_shift is itself representable up to 30. Not validated by the kernel.
