Register Window

Register Window

DESCRIPTION

The Register window enables you to take a close look at the way your program uses the machine. You can view the following information:

• the contents of the 16 general purpose registers (debugger variables $r0 through $r15) in hexadecimal format

• the contents of the 4 floating-point registers (debugger variables $f0 through $f6) in both hexadecimal and floating-point format

• the address of the current instruction (debugger variable $iad) in hexadecimal format

• the address mode.

The only way to open the Register window is with the window open register command. Issuing a window open register command when the Register window is already open causes it to be updated. Pressing ENTER also updates it.

Each of the registers and the current instruction address is associated with a debugger variable. These variables are assigned values that are based on the contents of the register. For example, using the Register window as shown above, you can determine that debugger variable $r0 has a value of 0x0180016c , which was derived from the contents of general purpose register 0. Debugger variables can be used as arguments to commands, such as the print and dump commands, that support expressions.
