Operation
Opening and closing the window
The [Registers] window opens automatically at debugger startup (unless the gdbtk.ini file is modified).
Clicking the [Close] button closes the window. The window can also be minimized.
To reopen the window, choose [Registers] from the [View] menu in the [Source] window or click the [Registers]
button.
[Registers] button
Only one instance of the [Registers] window can be open at one time. Any attempt to open the [Registers]
window while already open activates a new [Registers] window, which moves to the front of the screen.
Changing display format
The display format of registers can be selected from the following:
Hex:
Hexadecimal (default)
Decimal:
Signed decimal
Unsigned:
Unsigned decimal
Natural:
Common representation for the data type (e.g. decimal for int type values, hexadecimal for
pointers)
Binary:
Binary
Octal:
Octal
Raw:
8-digit hexadecimal
Floating Point: Floating point
Choose the register whose display format you wish to change by clicking it. (Clicking once more deselects the
register.) The name of a selected register is highlighted in blue.
Next, choose the desired display format from the [Format] submenu of the [Register] menu.
Otherwise, you can choose from the popup menu shown below that appears by right-clicking.
rewriting register data
The contents of registers can be changed directly in the window. Choose the register whose content you wish
to change by clicking it. Next, choose [Edit] from the [Register] menu. The register value is then highlighted in
blue, with a text cursor displayed after the value, indicating that the register is in edit mode. A register can also
be placed in edit mode by double-clicking it.
Enter a new value in decimal or hexadecimal to replace the existing value or alter the necessary digits of the
existing value. You can use the arrow, backspace, and delete keys.
Note that if a value exceeding the register size is entered, only the 24 low-order bits are handled as valid, with
those after bit 24 ignored.
