Indirect Branch Tracking

The ENDBR32 and ENDBR64 (collectively ENDBRANCH) are two new instructions that are used to mark valid indirect CALL/JMP target locations in the program. This instruction is a NOP on legacy processors for backward compatibility.

The processor implements a state machine that tracks indirect JMP and CALL instructions. When one of these instructions is seen, the state machine moves from IDLE to WAIT_​FOR_​ENDBRANCH state. In WAIT_​FOR_​ENDBRANCH state the next instruction in the program stream must be an ENDBRANCH. If an ENDBRANCH is not seen the processor causes a control protection fault (#CP), otherwise the state machine moves back to IDLE state.
