the last line of the old window is displayed as the first line of the new window. ( ski only) See “ski Register Window Commands” on page 5-1.

rb [count]

Moves the Register Window “backward” (scroll up) through the currently-displayed register set. The Register Win- dow is scrolled count lines. If count is omitted, the Register Window scrolls up one windowful less one line, i.e. the first line of the old window is displayed as the last line of the new window. ( ski only) See “ski Register Window Commands” on page 5-1.

rd [filename ]

Dump the Register Window to the screen or to the file given by filename . See “Register Window Commands” on page 5-1.

romload filename address [mapfile ]

Load an MS-DOS .com-format file for IA-64, IA-32, or mixed system-mode simulation. address specifies where to load the program. mapfile provides Ski with the mapping between program-defined symbols and their addresses and must specify an ASCII text file exactly compatible with mapfiles produced by the Microsoft “ML” linker. See “How to Load a Program” on page 6-3.

step [count]

Execute count instructions or, if no count is specified, one instruction. See “Program Execution” on page 6-5.

step until expression_without_spaces

Execute instructions until the expression_without_spaces has a non-zero value. See “Program Execution” on page 6-5.

save filename

Save the state of a simulated processor in the file given by filename . Only the registers and memory of the simulated processor are saved; state information private to the simulator such as cycle counts is not saved. See “Saving and Restoring the Simulator State” on page 8-8.

sdt

Show the Data Translation Lookaside Buffer (DTLB) (system-mode only). See “System-Mode TLB Simulation” on page 6-2.

sit

Show Instruction Translation Lookaside Buffer (ITLB) (system-mode only). See “System-Mode TLB Simulation” on page 6-2.

sr

ski: Show the system registers (Control Registers, Region Registers, Debug Registers, Protection Key Registers, Data Breakpoint Registers, Instruction Breakpoint Registers, Performance Monitor Configuration Registers, Perfor- mance Monitor Data Registers) in the Register Window. See “Register Window Commands” on page 5-1.

xski: Toggle the display of the system registers pane. See “Register Window Commands” on page 5-1.

symlist [filename ]

Write program-defined symbols to the screen or to the file given by filename . See “Symbol Table Commands” on page 8-8.
