An apparatus for detecting base-register usage conflicts in computer code includes a parsing module configured to parse source code, an identification module configured to identify statements in the source code that reference a base register for address resolution according to base-displacement form, and a determination module configured to determine whether a base register referenced by one statement matches the base register referenced by another. If two statements do reference the same register, an apparatus and method in accordance with the invention may notify a user such that corrective action may be taken.
