TSB

Trace synchronization barrier

This instruction is a barrier that synchronizes the trace operations of instructions, see Trace Synchronization Barrier (TSB). For information about the synchronization behavior when a DSB instruction follows a TSB instruction in program order, see:

If FEAT_TRF is not implemented, this instruction executes as a NOP.
