"""Trace FIFA17's PMA ScenarioModeStart-to-event-5 producer chain.
|
||||
|
||||
The generated GDB program uses hardware breakpoints, only reads registers and
|
||||
client memory, logs, and continues. Breakpoints are rotated so no more than four
|
||||
are enabled. It never calls client functions, writes client memory, emits an
|
||||
event, or drives input.
