A method and system for branch prediction are provided herein. The method includes executing a program, wherein the program comprising multiple procedures, and setting bits in a taken branch history register to indicate whether a branch is taken or not taken during execution of instructions in the program. The method further includes the steps of calling a procedure in the program and overwriting, responsive to calling the procedure, the contents of the taken branch history register to a start address for the procedure.
