The principal difference in the debugger is in the appearance of the Register window. The procedure for viewing the Register window is the same as for the x86 edition: while debugging a running program, choose Registers from the Debug menu (or press ALT+5).
Registers on Alpha are not the same as on x86. Additionally, the Program Status Register (psr) is equivalent to the register window flags used in the x86 edition.
Alpha processors have 32 general integer registers, each of which is 64 bits wide, and 32 floating-point registers, each of which is 64 bits wide.
The following figure shows a typical display of the Register window when running on an Alpha platform.
