Abstract
Embodiments include storing return addresses for a branch-target-buffer. Aspects include receiving a first instruction and based on a determination that the first instruction is a branch instruction and potentially a call, storing a return address associated with the branch instruction in a prediction return address table, wherein the prediction return address table includes an entry that corresponds to an index value that is created based on a target address of the first instruction, and wherein the entry includes the return address that is created based on an address of a sequential instruction of the first instruction. Aspects also include receiving a second instruction and based on a determination that the second instruction is predicted to be a return instruction with a predicted return address table index value from the branch-target-buffer, using the index value to select the return address to predict as the target address.
