What do you mean? Oracular? More or less? Executing the branch? Function return vs function call? This sounds like garbage I'm afraid.

There seems to be some fundamental basic misconceptions.

First of all, there is no "trivial", "sorta", or "more or less" about it. Function returns are predicted (and predicted well), and speculatively executed beyond. The "oracle" is called the branch predictor. The instructions after the "return" branch that redirects instruction pointer to the caller can execute in parallel with or even before the return branch is executed.

Second, none of the useful work that occurs after a branch is "independent". It all depends on the outcome of the branch. The point is that speculation can run in parallel or ahead of execution of branches.

Third, terminology may differ a bit, but a branch is not executed until its inputs are available, same as any other instruction. Fetch and prediction and speculative execution of instructions before an earlier branch has executed is not executing the branch itself. Executing determines the actual result of the branch, then that result will be sent to units responsible for branch prediction and for resteering the pipeline in case of a miss.

There is nothing special about a function or return from CPU point of view, it's just control flow redirection. Special case is that the call/return is recognized by branch prediction, but it has no fundamental different effect on operation of the pipeline.
