The Registers window (Figure 11) has the four standard menus at the top of the window, under which is a data area for showing the set registers and, alongside, a scroll bar for viewing all the source code.
Figure 11: Registers window
At the top of the data area are register values headings, and at the left are designators for controlling registers set by the Options menu (Figure 12). Depending on the register values and alphanumeric registers you choose, you will see more or fewer choices in the data area. Shown in Figure 11 are the representations for Natural, Decimal, Hex, Octal and Raw values.
For more on registers when debugging (used for setting machine register contents such as for program counters, stack pointers, or the status of a stack frame or the processor), see Examining Data in Debugging with GDB.
Each selected option will indicate the relative representation for register values.
