Chapter 12: Emulator/Analyzer Interface Commands
modify software_breakpoints
modify software_breakpoints
This command changes the specification of software breakpoints.
Software breakpoints provide a way to accurately stop the execution of your
program at one or more instruction locations. When a software breakpoint is set,
the instruction that is normally at that location is replaced with a TRAP instruction.
When the software breakpoint is executed, control is passed to the emulator's
monitor program, and the original instruction is restored in the user program. Thus,
execution is interrupted before the instruction at the specified address is executed.
Operation of the program can be resumed after the breakpoint is encountered, by
specifying either a run or step command.
If you modify software breakpoints while the memory mnemonic display is active,
the new breakpoints are indicated by a "*" in the leftmost column of the instruction
containing the breakpoint.
The software breakpoint facility may be completely disabled or enabled via the
"modify software_breakpoints" command. The default is "enabled".
