摘要
This invention describes how to avoid data loss due to limited buffer size during continuous tracing of high frequency events such as branches. Buffer data loss is adaptively avoided by either temporarily patching an instruction with a jump to itself or by using delay loops with an adaptive number of iterations during exception handling in which the trace event is written to the buffer.
