ABSTRACT OF THE INVENTION A method and system for handling a branch instruction which requires branching from a current instruction of a first instruction sequence to the first instruction of a second instruction sequence. The branch instruction is fetched and the next instruction of the first sequence is fetched while the branch instruction is displacement formatted. The first instruction of the second sequence is fetched while such next instruction is displacement formatted and the branch instruction is executed. The second instruction of the second sequence is fetched while the first instruction is displacement formatted, but the next instruction of the first sequence is not executed so that an execution wait occurs. The third instruction of the second sequence is then retched while the second instruction is displacement formatted and the first instruction is executed.
