A control transfer instruction (CTI), such as a branch, jump, etc., may have an offset value for a control transfer that is to be performed. The offset value may be usable to compute a target address for the CTI (e.g., the address of a next instruction to be executed for a thread or instruction stream). The offset may be specified relative to a program counter. In response to detecting a specified offset value, the CTI may be modified to include at least a portion of a computed target address. Information indicating this modification has been performed may be stored, for example, in a pre-decode bit. In some cases, CTI modification may be performed only when a target address is a “near” target, rather than a “far” target. Modifying CTIs as described herein may eliminate redundant address calculations and produce a savings of power and/or time in some embodiments.
