The tracei command shows machine instructions, function calls, or variable changes. It is valid only in native mode.
tracei is really a shorthand for trace event-specification -instr where the- instr modifier causes tracing to happen at instruction granularity instead of source line granularity. When the event occurs, the printed information is in disassembly format instead of source line format.
