Deleting Program Breakpoints | HP IA-64, Ski Simulator guide

Ski IA-64 Simulator Reference Manual 1.0L

Figure 8-3. Three Breakpoints, 0, 2, and 1, Visible in xski’s Program Window

8.3.2Deleting Program Breakpoints

Two commands delete program breakpoints. The bd command deletes a speciﬁed breakpoint. The bD command deletes all breakpoints currently set.

8.3.3Listing Program Breakpoints

The bl command causes a list of currently set program breakpoints to be displayed on the screen, symbolically if possible, as shown in Figure 8-4.The ﬁrst column of the display shows the breakpoint number, for use with the bd command. The second column displays a “ P” for physically-addressed breakpoints and “ V” for virtually-addressed breakpoints. The col- umn labelled “Address” is, of course, the breakpoint address. In the next column, “ IA-64” indicates a breakpoint in IA-64 code and “ IA-32” indicates a breakpoint in IA-32 code. The “Command” column is currently unused.
