A +pass count of five means that this tracepoint will issue a silent +"tstop" when it is hit the fifth time (after it has performed all +it actions). A pass count of zero (0) means that the tracepoint +will never causes the trace experiment to terminate on the target.</P> + +<P>To <A NAME="t_actions_add">add an action</A> for the tracepoint, +select the appropriate action from the Action ComboBox and click +"Add". The <A HREF="#actionsdlg">Action Dialog</A> appears to +allow editing the action's properties.</P> + +<P>Currently, there are two actions: collect and while-stepping. +Any number of collect actions may be added to specify that the +target should collect variables, registers, and memory when +it is hit. The while-stepping action may be used to collect +data for a specified number of machine instructions. Only one +while-stepping action may be specified for any tracepoint.</P> + +<P>To <A NAME="t_actions_modify">modify the actions</A> associated +with a tracepoint, double-click the left mouse button on the action +listed in the Action Frame, and the <A HREF="#actionsdlg">Actions +Dialog</A> will appear.</P> + +<P>To accept the tracepoint as displayed, click the OK button.

To delete +the tracepoint (if it is not a new tracepoint), click the DELETE button.</P> + +<H3><A NAME="actionsdlg">The Actions Dialog</A></H3> +The Actions Dialog is used to edit an action for the tracepoint. It +consists of two lists, one containing all (uncollected) local variables +(including function arguments) and registers, and one containing everything +being collected. + +<P>The <A NAME="#a_variables">Variables List</A> lists all uncollected local variables, +function arguments, and registers and may also display the special indentifiers +"All Locals", "All Arguments", and "All Registers".

To specify a range of variables to be +collected, select them in the Variables list and click the "<<< Collect" button.</P> + +<P><A NAME="a_collect">The Collection List displays all data being collected +by the action, including the special types "All Locals", "All Registers", and +"All Arguments", which specify that every local variable, every register, and +every function argument will be collected, respectively. Specifying a local +variable, for example, and "All Locals" will cause only the special identifier +"All Locals" to be sent to the target. Analogously, "All Registers" and "All +Arguments" also override any register or function argument specifically listed +in the Collection List.</P> + +<P>To remove data from the Collection List, double-click any of the entries listed +in the List, or select a range of data to be removed and press the "Ignore >>>" +button. All local variables, function arguments, registers, and special identifiers +will be returned to the Variable List, while any expression (memory ranges, globals) +will simply "disappear". To add these again, use the <A HREF="#a_other">Other Entry</A> +at the bottom of the display.</P> + +<P>The <A NAME="#a_other">Other Entry</A> can be used to move any variable listed in +either the Collection List or the Variable List to the other list. It can also +be used to specify expressions for collection, such as memory ranges and global variables. +Simply enter the name of the global variable or the expression and press the enter key on +the keyboard. If the expression is valid, it will be added/removed from the Collection +List.</P> +</BODY> +</HTML> |
