522 * (debug_execution true), since the breakpoints would be set to match
523 * target firmware being debugged, not the helper algorithm.... and
524 * enabling them could cause such helpers to malfunction (for example,
525 * by overwriting data with a breakpoint instruction. On the other
526 * hand the infrastructure for running such helpers might use this
