Abstract
Method, system, and computer program product embodiments for performing a branch trace operation on a computer system of an end user are provided. An encrypted mapping macro is provided to the end user to be made operational on the computer system. A trace program is provided to the end user. The end user executes the trace program on the computer system as a diagnostic tool. The trace program is adapted for decrypting the encrypted mapping macro, determining a storage offset location of a branch instruction; checking the storage offset location for an identifying constant, cross referencing the identifying constant with an entry in the decrypted mapping macro to identify a branch triggering bit and diagnostic information associated with the branch instruction, and returning the branch triggering bit and diagnostic information, the branch triggering bit and diagnostic information provided to a coder.
