Platform independent memory image analysis architecture for debugging a computer program

In a computer platform having a computer program that includes definitions of data types and a facility for generating memory images for the computer program far use in analyzing the computer program, a method comprising the steps of:

• providing a memory image that has been generated by the memory image facility, said memory image being a recording of contents of a memory space used by the computer program;
• processing the computer program to identify computer system independent attributes of the selected data type;
• storing the identified computer system independent attributes in a template for use in accessing data in the memory image of the selected data type;
• and
• creating a data type object for the selected data type to hold information regarding the selected data type and storing information contained in the template in the data type object.

In a computer system of a given hardware architecture having a computer program that defines at least one data type and an analysis facility for analyzing data for the computer program, a computer-readable medium holding computer-executable instructions for performing a method comprising the steps of:

• providing a memory image for the computer program, said memory image being a recording of contents of a memory space used by the computer program;
• providing a information regarding a context in which the computer program runs;
• with the analysis facility, identifying information context in which the computer program runs that influences attributes of the data type and that identifies that the computer system has the given hardware architecture;
• and
• employing the information identified in the context in which the computer program runs in analyzing the memory image for the computer program with the platform agnostic analysis facility.

In a computer system of a given hardware architecture having a computer program that defines a data type and analysis facility for analyzing data for the computer program, a transmission medium for transmitting computer-executable instructions for performing a method comprising the steps of:

• providing a memory image for the computer program, said memory image being a recording of contents of a memory space used by the computer program;
• providing a program operation context that provides information regarding a context in which the program runs;
• with the analysis facility, identifying information in the program operation context that influences attributes of the data type;
• creating a view of the data type based on the information that is identified;
• and
• employing the view of the data type in analyzing the memory image for the computer program with the analysis facility.
