Figure 222: Action Point Tab
Setting Breakpoints and Barriers
The icon is what TotalView displays when you create a breakpoint
on an assembler statement.
CLI: All action points display as “@” when you use the dlist command to
display your source code. Use the dactions command to see what
type of action point is set.
When you’re program halts because it encountered an action point,
TotalView lets you know what has happened in several ways. In the Root
Window, the status is displayed with the letter “b” followed by a number.
This is the same number that you will see in the Action Points tab within
the Process Window. In the Process Window, the status lines above the
Source Pane also let you know that the thread is at a breakpoint. Finally,
TotalView places a yellow arrow over the action point’s icon in the Action
Point tab. For example:
If you are working with templated code, you will see ellipses (...) after the
address. These ellipses indicate that there are additional addresses associated
with the breakpoint.
Setting Breakpoints and Barriers
TotalView has several options for setting breakpoints. You can set:
� Source-level breakpoints
� Breakpoints that are shared among all processes in multi-process programs
� Assembler-level breakpoints
You can also control whether TotalView stops all processes in the control
group when a single member reaches a breakpoint.
