    • A method and apparatus for evaluating software application performance utilizing a compiler application. An evaluation function is created which may be utilized to track and store software application execution information at each invocation thereof. A software application to be evaluated is compiled utilizing a compiler application which inserts at least one prelude routine command during compiling which is utilized to invoke the prelude routine upon each entry to a procedure within the software application. A command invoking the evaluation function is inserted into the prelude routine such that each entry to a procedure within the, software application under evaluation will result in the storage of execution information at that point. In the depicted embodiment of the present invention execution information at each exit from a procedure within the software application is also tracked and stored by invoking the evaluation function automatically prior to returning from a current procedure.
    • 一种用于使用编译器应用程序评估软件应用程序性能的方法和装置。 创建评估功能,其可用于在其每次调用时跟踪和存储软件应用执行信息。 使用编译器应用程序来编译要评估的软件应用程序,该编译器应用程序在编译期间插入至少一个前奏程序命令,该编译器应用程序在每次输入到软件应用程序中的过程时用于调用前奏程序。 将调用评估函数的命令插入到前奏例程中,使得在评估中的软件应用程序内的过程的每个条目将导致在该点存储执行信息。 在本发明的所描绘的实施例中,通过在从当前过程返回之前自动调用评估函数来跟踪和存储在软件应用程序内的每个出口处的执行信息。

    • A method and apparatus in a data processing system for generating a metadata stream. An attribute call is received to set an attribute. In response, a first database is queried to determine whether the attribute call is present in the first database. The first database is updated in response to the attribute call being absent in the first database. In response to receiving a primitive call, an attribute call associated with the primitive is retrieved from the first database. A determination is made as to whether the attribute call associated with the primitive is present in a second database. The second database is; updated to include the attribute call associated with the primitive call in response to the attribute call associated with the primitive call being absent in the second database. The attribute call associated with the primitive call and the primitive call is placed in the metadata stream.
    • 一种用于生成元数据流的数据处理系统中的方法和装置。 接收属性调用以设置属性。 作为响应,查询第一数据库以确定属性调用是否存在于第一数据库中。 响应于第一个数据库中不存在的属性调用更新了第一个数据库。 响应于接收到原始呼叫,从第一数据库检索与原语相关联的属性调用。 确定与基元相关联的属性调用是否存在于第二数据库中。 第二个数据库是 更新为包括与基本调用相关联的属性调用以响应于与第二数据库中不存在的原语调用相关联的属性调用。 与原始调用和原语调用相关联的属性调用被放置在元数据流中。
