Extended Basic Block

A sequence or batch of instructions that logically belong together. They have one entry point, and can only be entered at that entry point, and one or more exit points. On the Mill there is no implicit exiting an EBB, so every ends with an explicit control flow operation. The EBB plays a central role for organizing code on the Mill. For one, jump addresses are encoded relative to the start of the current EBB. Branch prediction works on EBB exits instead of branches.
