Abstract
An aliasing method and apparatus carried out on a digital computer are provided for generating an object code from a source program. An aliasing data structure is defined and includes an initial empty check-list for each variable in the source program. A pseudo variable is constructed to represent each predefined large alias class. The pseudo variable is attached to the check-list of each variable included in the predefined alias class. Inverse alias checking upon use of a variable is provided using the check-lists for the variable.
