Flexible horizontal stack display and editor

1. A computer-implemented method for debugging a computer program, comprising:

retrieving stack frame data associated with a first function being executed within the computer program from a stack;

retrieving stack frame data associated with a second function being executed within the computer program from the stack;

processing the stack frame data associated with the first function;

processing the stack frame data associated with the second function;

displaying a stack window in a user interface;

rendering a first data representation corresponding to the stack frame data associated with the first function in a first sub-window of the stack window; and

rendering a second data representation corresponding to the stack frame data associated with the second function in a second sub-window of the stack window.

2. The method of claim 1 , further comprising displaying a source code window in the user interface.

3. The method of claim 2 , further comprising displaying the stack window on top of the source code window in the user interface.

4. The method of claim 1 , further comprising displaying a re-assembled machine code window in the user interface.

5. The method of claim 4 , further comprising displaying the stack window on top of the re-assembled machine code window in the user interface.

6. The method of claim 1 , further comprising adjusting the size of the first sub-window of the stack window.

7. The method of claim 6 , further comprising adjusting the size of the second sub-window of the stack window.

8. The method of claim 6 , wherein adjusting the size of the first sub-window of the stack window comprises performing a point and click method with a cursor control device.

9. The method of claim 1 , further comprising displaying high-level stack data associated with the first function in a first display area of the first sub-window of the stack window.

10. The method of claim 9 , wherein the high-level stack data associated with the first function includes a set of variables and a value stored in each of the set of variables during execution of the first function.

11. The method of claim 9 , further comprising adjusting the size of the first display area of the first sub-window of the stack window.

12. The method of claim 9 , further comprising displaying low-level stack data associated with the first function in a second display area of the first sub-window of the stack window.

13. The method of claim 12 , wherein the low-level stack data associated with the first function includes a plurality of memory locations, data stored at each of the plurality of memory locations, and a program symbol associated with each of the plurality of memory locations.

14. The method of claim 1 , further comprising:

retrieving stack frame data associated with a third function being executed within the computer program from the stack;

processing the stack frame data associated with the third function;

rendering a third data representation corresponding to the stack frame data associated with the third function in a third sub-window of the stack window.

15. The method of claim 14 , further comprising adjusting the size of the third sub-window of the stack window.

16. The method of claim 14 , further comprising:

displaying high-level stack data associated with the third function in a first display area of the third sub-window of the stack window; and

displaying low-level stack data associated with the third function in a second display area of the third sub-window of the stack window.

17. The method of claim 1 , further comprising closing at least one of the first sub-window of the stack window and the second sub-window of the stack window.

18. The method of claim 14 , further comprising closing at least one of the first sub-window of the stack window, the second sub-window of the stack window, and the third sub-window of the stack window.

19. A computer-readable medium that provides instructions that, when executed on a processor, cause the processor to perform the following method:

retrieving call stack data associated with a computer program from memory, wherein the call stack data includes information pertaining to a first function being executed within the computer program and information pertaining to a second function being executed within the computer program;

displaying the information pertaining to the first function in a first sub-window of a stack window; and

displaying the information pertaining to the second function in a second sub-window of the stack window, wherein the first sub-window of the stack window and the second sub-window of the stack window are arranged horizontally within the stack window.

20. A computer-implemented method for debugging a computer program, comprising:

retrieving information pertaining to a first function being executed within the computer program from a stack and displaying the information pertaining to the first function in a first sub-window of a stack window;

retrieving information pertaining to a second function being executed within the computer program from the stack and displaying the information pertaining to the second function in a second sub-window of the stack window;

determining whether a command to change the size of at least one of the first and second sub-windows is received and, in response to a positive determination, changing the size of at least one of the first and second sub-windows;

determining whether a command to update at least a portion of the information pertaining to the first function or the information pertaining to the second function is received and, in response to a positive determination, updating at least a portion of the information pertaining to the first function or the information pertaining to the second function.
