摘要:
A method for retrieving a return address from a link stack when returning from a procedure in a pipeline processor is disclosed. The method identifies a retrieve instruction operable to retrieve a return address from a software stack. The method further identifies a branch instruction operable to branch to the return address. The method retrieves the return address from the link stack, in response to both the instruction and the branch instruction being identified and fetches instructions using the return address.
