If the number parameter is specified, only magic instructions with that argument value are considered. The possible argument values depends on the processor type. To consider all magic instructions, the -all flag can be used. The default is to consider magic instructions with argument 0.
If no processor object is specified, magic instructions from all processors are considered.
See further about magic breakpoints in Simics User's Guide.
The -once flag causes the breakpoint to automatically be removed after it has triggered.
