<H1>The Register Window</H1>
|

|

<P>The Register Window lists registers and their contents for
|
||
|
|
the selected stack frame. It permits viewing the contents of registers
|
||
|
|
in different formats, editing register values, and some display
|
||
|
|
customizations.</P>

|
|
<p>In the image above, you can see all the registers on the left and their values on the right.
|
||
|
|
At the top is an option menu to allow you to choose what group of registers to display.
|
||
|
|
The groups names are preset according to the architecture being debugged. The default is "all".
|
||
|
|
Registers highlighted in green have recently changed.
|
||
|
|
</p>
|
||
|
|
<P>The Register Window will update the register contents in the display
|
||
|
|
to match the stack frame currently being viewed in the <A HREF="source.html">
|
||
|
|
Source Window</A> and <A HREF="stack.html">Stack Window</A>.</P>
|
||
|
|
<p>Each time the program stops, the register window will automatically update.
|
||
|
|
Registers that have changed since the last stop will be displayed in green.</p>

<H3>The Register Pop-up Menu</H3>
|

<img src="images/reg_menu.png" alt="register popup menu" width=396 height=388 border=0>
|
||
|
|
<P>
|
||
|
|
To activate the pop-up menu, click the right mouse button over a register.
|
||
|
|
This will allow you change the way the register is displayed, or to remove
|
||
|
|
it from the display. Or you can add the register to the watch window.
|
||
|
|
For integer registers, you can also open a memory window at the
|
||
|
|
location pointed to by the register.</P>

<H3>Editing a Register</H3>
|
||
|
|
<P>
|
||
|
|
To edit a register, simply click on it with the left mouse button. Type
|
||
|
|
in the new value and hit enter. You can enter a decimal, hex, or float number and
|
||
|
|
the type will be converted if possible. You may also enter an expression to be evaluated.
|
||
|
|
For example, to set $r3 to the same as $r4, edit $r3 and enter "$r4" as the value. In the same
|
||
|
|
way, you can set $pc to "main".
|
||
|
|
The value of the register is set to the current value of the expression; it will not be reevaluated
|
||
|
|
if the expression's value later changes.
|
||
|
|
</P>
|
||
|
|
<P>Press the escape key on the keyboard to cancel your edit.</P>
