Unified and Generative Debugging

Analysis, Architectural, Design, Implementation and Usage Debugging Patterns

This is another tracing example of unified debugging patterns introduced previously in Volume 6 (page 172).

•    Usage Patterns

Saving a memory address obtained at a breakpoint event in a debugger pseudo-register for use at later breakpoint events

Debugging TV¹⁰⁰ published a case study for tracing window messages in WinDbg¹⁰¹. There a pseudo-register is used to save a buffer address before GetMessage call and then to reuse it after the call. Please look at Event State Management slide on Frames episode 0×06 presentation¹⁰². The full WinDbg log and the recording are available there too¹⁰³.
