A system and method for improved testing of a software build is provided. The system and method automatically track differences between software builds by scanning the binaries of a software product to automatically discover its classes. The system and method then build a detailed dictionary that captures static and dynamic information of that build, including class dependencies. A comparison may be made with another build, so that the present invention may automatically execute selective tests on any types, and their dependencies, that have had a structural or behavioral modification since the last build. Testers may load a set of constructors for any specific types to further increase coverage of types (or classes) tested. The present invention may also provide detailed reports that may be used to drive future testing work and target specific areas of the code for additional testing. The system and method may further provide code generation from intermediate code to specified targets to aid in reproducing and fixing bugs.

A computer system for generating a cause effect matrix as a user interface to develop a control program based on the cause effect matrix and to compile and download the resulting program into a programmable controller. A cause effect matrix diagram is used to develop a function block diagram program which is a standard IEC 1131-3 language. The function block diagram is translated into structured text which is compiled into intermediate code. The intermediate code is translated into the native code for the micro-processor of the target control system, including but not necessarily limited to the Motorola processor MPC-860. The automation of a cause effect matrix diagram to generate a function block diagram permits additional capability by allowing functions for causes, intersections, and effects. Because special functions may be included, the results of a cause generate timing functions or other computations before initiating the effect.

Form controls of the data form are instantiated using the intermediate code. Hypertext Markup Language (HTML) is generated from the intermediate code including the form controls.

One embodiment of the present invention provides a system that facilitates locked prefetch scheduling in general cyclic regions of a computer program. The system operates by first receiving a source code for the computer program and compiling the source code into intermediate code. The system then performs a trace detection on the intermediate code. Next, the system inserts prefetch instructions and corresponding locks into the intermediate code. Finally, the system generates executable code from the intermediate code, wherein a lock for a given prefetch instruction prevents subsequent prefetches from being issued until the data value returns for the given prefetch instruction.

A high-sped block is formed by generating and connecting a new basic block (contains an intermediate code obtained by performing variable replacing processing to a path replacement target variable of the intermediate code on a hot path of an original partial program and contains a branching intermediate code where a branching instruction on the hot path is converted so as to execute the hot path), and a basic block with an intermediate code for restoring value of path guarantee variable among the path replacement target variables to a value of an original variable. When an execution result of a conditional branching intermediate code is true, the speeding up of the original program is achieved through executing the basic block, and performing dependency analysis and dependency generation between the intermediate codes in the high-speed block and scheduling of the instructions.

When a host computer transmits print data to a printer, the computer investigates the possibility of overrun per each band of band obtained by partitioning a page into bands. The host computer designates pre-rendering processing in regard to bands in which overrun is judged to be possible. Upon receiving the print data, the printer generates and compresses image data beforehand in regard to a band for which pre-rendering has been designated and stores the compressed image data. In case of a band for which pre-rendering has not been designated, the printer generates an intermediate code at a stage prior to the generation of image data from the print data. At the time of printing, image data is generated in one of two band buffers and image data is output from one band buffer. At this time the compressed image data is decompressed in case of a band for which pre-rendering has been designated, and image data is generated from an intermediate code in case of a band for which an intermediate code has been generated.

The printing mode for each page of a document can be efficiently selected at a preferable timing. A printer driver identifies a spooled intermediate code as color data or monochrome data, based on selected criteria. Based on the identification results, a page that has been identified as being ambiguous is displayed on a screen. The printing mode of the ambiguous page can be changed. Then, the change of the printing mode is confirmed. After the change is confirmed, the intermediate code is printed in accordance with the confirmed printing mode.

A printer includes an intermediate code preparation section that converts print data into intermediate codes for each band, and the thus-converted intermediate code is stored in memory. The intermediate code is expanded to bit-map data, and the bit-map data are transferred to a print engine. An expansion time measurement section measures the time required for expanding the intermediate code for each band. A comparison-and-determination section determines, for each band, whether or not the time required for expanding the intermediate code into the bit-map data exceeds a threshold value, thereby preparing a band management table. With regard to only the bands which exceed a threshold value, an expansion management table is prepared by copying the band management table. The expansion management table is converted into a sorted expansion management table in which bands are sorted in descending order of expansion time. Intermediate codes for the bands are expanded beforehand into bit-map data in descending order from a higher band to a lower order band in the sorted expansion management table, so long as memory for expansion is reserved.
