Examining Registers

Select one of the Show:Registers menu items to display a dialog box that shows the contents of a group of hardware registers. Figure 4-2 shows a dialog box displaying general registers. You can also display ￿oating point and special registers.

From the Show Registers dialog box, you can:

1.View register contents.

Register values that change during execution are highlighted.

2.Specify how the the register values are updated (similar to setting a watchpoint's granularity).

You can also temporarily suspend updating, which allows the target program to run faster. When register tracing is activated and set to anything other than Every Stop, the debugger creates an implicit watchpoint to check the register values at the appropriate granularity.

3.Change from the default hexadecimal display format.

The ￿oating point register dialog box allows you to specify whether the registers are displayed as two 4-byte values (single precision) or one 8-byte value (double precision).
