Detailed Description

Performs type conversion from an arbitrary input type to a type that is expressed by a QuantizedType.

This handles cases where the inputType is a supported primitive type (i.e. f32, bf16, etc) or a vector/tensor type based on a supported elemental type.

Since conversion often involves introspecting some attributes of the input type in order to determine how to represent it, this is a two step process.

◆ convert()

Type ExpressedToQuantizedConverter::convert ( QuantizedType elementalType ) const

Member Data Documentation

◆ expressedType

const Type mlir::quant::ExpressedToQuantizedConverter::expressedType

Supported, elemental expressed type (i.e.

f32). Will be nullptr if conversion is not supported.
