Function Documentation

fakeQuantAttrsToType() [1/2]

UniformQuantizedType mlir::quant::fakeQuantAttrsToType	(	Location	loc,
		unsigned	numBits,
		double	rmin,
		double	rmax,
		bool	narrowRange,
		Type	expressedType,
		bool	isSigned = false
	)

Converts per-layer FakeQuant attributes to the corresponding type.

In the event that the parameters cannot be converted, returns a nullptr convertible Type and issues an appropriate error. Note that there are multiple variants of a per-layer FakeQuant op, so this function takes the attributes discretely vs taking a reference to the originating op.
