Interpreting Status and Control Registers

The Stack Frame Pane in the Process Window lists the contents of CPU registers for the selected frame--you may need to scroll past the stack local var-iables to see them. To learn about the meaning of these registers, you need to consult the user's guide for your CPU and Architectures.

For your convenience, TotalView displays the bit settings of many CPU registers symbolically. For example, TotalView symbolically displays registers that control rounding and exception enable modes. You can edit the values of these registers and continue execution of your program. For example, you might do this to examine the behavior of your program with a different rounding mode.

Since the registers that are displayed vary from platform to platform, see Architectures for information on the registers supported for your CPU. For general information on editing the value of variables (including registers), refer to Displaying Areas of Memory.
