In my last article, I used Last Branch Record (LBR) Trace to manually capture UEFI program flow source and destination addresses. This week, I look at the associated instruction opcodes and mnemonics and try to figure out what is going on.

My curiosity got the better of me this week. I decided to play detective, and see what I can learn from LBR trace data if I pretend I don’t have access to the source code.

In Episode 12, I wrote a simple “Hello World!” application in ‘C’ using the built-in UEFI shell functions. In Episode 13, I failed in an attempt to re-write that application using standard ‘C’ library functions, such as printf(). I’ve learned a lot since then – here’s how to write more sophisticated programs.
