IntType

public struct IntType : IRType
extension IntType: Equatable

The IntType represents an integral value of a specified bit width.

The IntType is a very simple type that simply specifies an arbitrary bit width for the integer type desired. Any bit width from 1 bit to (2^23)-1 (about 8 million) can be specified.
