Trap entry point rust (_start_trap_rust)

scause/mcause is read to determine the cause of the trap. XLEN-1 bit indicates if it’s an interrupt or an exception. The result is examined and ExceptionHandler or one of the core interrupt handlers is called.

Safety

This function should not be called directly by the user, and should instead be invoked by the runtime implicitly.
