579 * @param current True to use the target's saved program counter instead
580 * of the address parameter
581 * @param address Optionally used as the program counter.
582 * @param handle_breakpoints True iff breakpoints at the resumption PC
583 * should be skipped. (For example, maybe execution was stopped by
584 * such a breakpoint, in which case it would be counterprodutive to
586 * @param debug_execution False if all working areas allocated by OpenOCD
587 * should be released and/or restored to their original contents.
588 * (This would for example be true to run some downloaded "helper"
589 * algorithm code, which resides in one such working buffer and uses
590 * another for data storage.)
592 * @todo Resolve the ambiguity about what the "debug_execution" flag
593 * signifies. For example, Target implementations don't agree on how
594 * it relates to invalidation of the register cache, or to whether
595 * breakpoints and watchpoints should be enabled. (It would seem wrong
596 * to enable breakpoints when running downloaded "helper" algorithms
597 * (debug_execution true), since the breakpoints would be set to match
598 * target firmware being debugged, not the helper algorithm.... and
599 * enabling them could cause such helpers to malfunction (for example,
600 * by overwriting data with a breakpoint instruction. On the other
601 * hand the infrastructure for running such helpers might use this
602 * procedure but rely on hardware breakpoint to detect termination.)
