摘要： A computer implemented method, apparatus and computer usable program code for marking instructions for instrumentation. A plurality of instructions is presented in a graphical user interface. A user input selecting a set of instructions in the plurality of instructions for instrumentation is received through the graphical user interface. A set of instructions is marked as a set of instrumentation instructions in response to receiving the user input. The set of instructions are executed by a processor if the processor is in an instrumentation mode, and the instrumentation instructions are unexecuted if an absence of the processor being in the instrumentation mode is present.

摘要： A method, apparatus, and computer instructions in a processor for associating a data type with a memory location. The type is associated with a location by means of metadata that is generated and manipulated by hardware instructions that are typically generated by a compiler as it generates the other instructions that comprise the machine code version of a program. A determination is made as to whether a data value about to be stored is of the required data type for that location. The hardware indicates an error condition if the types do not match.

摘要： A system and method for collecting a plurality of metrics during a single run of a computer program. The mechanism of the present invention initializes a plurality of counters to count events associated with metrics of interest. The mechanism of the present invention then counts the occurrence of events associated with metrics of interest during a single execution of a computer program. Responsive to a determination that a counter in a plurality of counters has generated an interrupt, the interrupt is rerouted to an interrupt handler, wherein the interrupt handler generates trace records comprising trace information corresponding to the interrupt. The mechanism of the present invention then generates profiles for the trace records, wherein the profiles differentiate the trace records based on the metric type associated with each trace record.

摘要： A method, system, apparatus, and computer program product is presented for tracing operations. A set of related methodologies can be used within instruction tracing software, such as a tracing program, to reduce its tendency to generate interrupts that cause unwanted effects in the system that is being captured. A first methodology allows access to protected memory blocks so that instructions may be read from those memory blocks. A second methodology provides for the trace output buffer to be accessed using physical addressing. A third methodology traces only instruction addresses, which are resolved later during a post-processing phase of operation. A fourth methodology comprises multiple different methods for obtaining copies of instructions that have already executed rather than obtaining them before they are executed.

摘要： A method, apparatus, and computer instructions for generating coverage data for accesses to dynamically allocated data during execution of code in a data processing system. In response to a request to dynamically allocate a memory area for dynamically allocated data, the memory area is dynamically allocated during execution of the code. The memory area is associated with a data access indicator in response to dynamically allocating this memory area. A determination is made as to whether an access to a memory location associated with the data access indicator has occurred, in response to executing an instruction in the code at a processor in the data processing system. If the data access indicator is associated with the memory area, a state of the data access indicator by the processor is changed when the instruction is executed. The coverage data for the dynamically allocated data is generated during execution of the code by the processor.

摘要： An apparatus and method are provided for the dynamic instrumentation of code to minimize system perturbation during tracing of the execution of the code. With the apparatus and method, “hot spots” in the execution of the code are dynamically determined during tracing of the execution of the code. These “hot spots” are dynamically instrumented, i.e. an event hook is inserted, to cause control to be passed to a handler that determines a caller of the “hot spot” method. The method that called the “hot spot” method, or “caller” method, is identified from a call stack and is dynamically instrumented for an appropriate metric so that the next time the calling method is executed, the dynamically inserted hooks are executed. The execution of the hooks in the caller method is continued for a predetermined period, e.g., number of invocations, to get an understanding of the caller method's characteristics. A list of callers of instrumented methods is maintained and used to determine one or more calling methods of the instrumented caller method. One or more of these calling methods may be instrumented and the hooks inserted in the instrumented caller method (called by the one or more calling methods), are removed. In this way, the call graph of the hot spots of a program execution is “walked up” and characterized over time.
摘要翻译：提供了一种用于在代码执行跟踪期间对代码进行动态检测以最小化系统扰动的装置和方法。利用该装置和方法，在代码执行的跟踪期间动态地确定代码执行中的“热点”。这些“热点”被动态地装配，即插入事件钩子，以使得控制被传递给确定呼叫者“热点”方法的处理程序。称为“热点”方法或“呼叫者”方法的方法是从调用堆栈中识别的，并为适当的度量进行动态检测，以便下次执行调用方法时，会执行动态插入的钩子。调用方法中的挂钩的执行持续一段预定时间，例如调用次数，以便了解呼叫者方法的特征。维护检测方法的呼叫者列表，并用于确定被调用呼叫者方法的一个或多个呼叫方法。可以对这些调用方法中的一个或多个进行检测，并且删除插入到被调用的调用方法中的钩子（由一个或多个调用方法调用）。以这种方式，程序执行的热点的调用图被“走过”并且随着时间的推移而被表征。
