Abstract

A processor framework includes a compiler to add control information to an instruction sequence at compile time. The control information is added in the instruction sequence prior to a control-flow changing instruction. Microarchitecture is configured to use the control information at runtime to predict an outcome of the control-flow changing instruction prior to fetching the control-flow changing instruction.
