A processor of an aspect includes a decode unit to decode a prior instruction that is to have at least a first context, and a subsequent instruction. The subsequent instruction is to be after the prior instruction in original program order. The decode unit is to use the first context of the prior instruction to determine a second context for the subsequent instruction. The processor also includes an execution unit coupled with the decode unit. The execution unit is to perform the subsequent instruction based at least in part on the second context. Other processors, methods, systems, and machine-readable medium are also disclosed.
