Struct melior::dialect::ods::quant::DequantizeCastOperation

pub struct DequantizeCastOperation<'c> { /* private fields */ }

A dcast operation. Convert back from a quantized to quantizable (expressed) type operation.

A DequantizeCast op dcast represents the inverse of a qcast, converting back from a quantized to quantizable (expressed) type.

Like qcasts, a dcast is allowed to have both its operand and result as non quantized types. This facilitates transformations and marks edges where the computation must be carried out in the expressed type.

Especially early in transformation, it is common to have dcasts on all operands to ops that must operate with the expressed type (typically math ops prior to lowering to target-specific, quantized kernels).
