CHAPTER 2 DEPENDENCE FUNCTIONS
2.3.6.6 Display Format of Trace Data
The trace data display format can be selected by running the SHOW TRACE command
with a command modifier specified. If setup is completed with the SET SOURCE
command so as to select a source line addition mode, a source line is attached to the
displayed trace data.
There are three formats to display trace data:
• Display in instruction execution order (Specify /INSTRUCTION.)
• Display all machine cycles (Specify /CYCLE.)
• Display in source line units (Specify /SOURCE.)
■ Display in Instruction Execution Order (Specify /INSTRUCTION.)
Trace sampling is performed at each machine cycle, but the sampling results are difficult to display because
they are influenced by pre-fetch, etc. This is why the emulator has a function to allow it to analyze trace data
as much as possible. The resultant data is displayed after processes such as eliminating pre-fetch effects,
analyzing execution instructions, and sorting in instruction execution order are performed automatically.
However, this function can be specified only in the single trace while in the debugging mode.
In this mode, data can be displayed in the following format.
