When either of the following operation has occurred, the program will stop automatically after conducting step execution in the source level (1 line of source text) or in the instruction level (1 instruction).
Once the program is stopped, the contents of each panel will be updated automatically. As such, step execution is suited for debugging the program execution in transition either in source or instruction level.
The unit in which the program is step-executed depends on the setting as follows:
button on the Editor panel’s toolbar is invalid (default):Step execution is conducted in source level.
Note, however, that when the focus is in the Disassemble panel or the line information does not exist in the address specified by the current PC value, the step execution is conducted in instruction level.
button on the Editor panel’s toolbar is valid:Step execution is conducted in instruction level.
button is only enabled if the Mixed display mode is selected on the Editor panel.Step execution is divided into the following types:
2.8.3.1 Step in function (Step in execution)
2.8.3.2 Step over function (Step over execution)
2.8.3.3 Execute until return is completed (Return out execution)
Breakpoints, break events, and action events that have been set do not occur during step execution. |
An error message will appear while processing a function prologue or epilogue if the return address cannot be acquired. |
