Ski IA-64 Simulator Reference Manual 1.0L 1 Getting Started: A Ski Tutorial In this chapter, you learn how to use Ski by executing a brief tutorial. At the end of the tutorial, you will learn where to look in this manual for detailed descriptions of Ski’s operation and commands. Introductory information on Ski is pre- sented in Chapter 2, “Overview”. 1.1 The Ski Simulator Ski simulates the IA-64 architecture and also has limited support for simulating IA-32 programs. Ski runs on IA-32 Linux host

The Four Primary xski Windows 1.2.2 Exiting Ski You can quit xski and this tutorial with the Quit button, with the File->Quit menu selection, or with the “quit” com- mand. All are in the Main Window. (Don’t quit now; you are just beginning!) 1.2.3 Loading Your Program Use the “Command” area of the “main” Window to load your program. For example, let’s say your program is the famous “Hello, world” program, the executable file is named “hello”,

The xski Register Window 1.2.4 Inspecting Data To look at theargv andenvp strings, you need to use the Data Window. Linux passesargc,argv, andenvp on the mem- ory stack (r12). To look at this memory area, use the “dj” command (“datajump”) in “Command” area of the Main Win- dow. Supply, as an operand, the address of the memory stack. For example, if r12 is set to 9ffffffffff780, you can Copyright © 2000 Hewlett

Ski IA-64 Simulator Reference Manual 1.0L type “dj r12”or“dj 9ffffffffff780”, as shown in Figure 1-7 and the Data Window changes to display the hexadec- imal data stored at the location, as shown in Figure 1-8. Find the value of r12 in your program and use “dj”now.(You might wonder why “dj” exists, instead of a simple scroll bar. Imagine scrolling through the entire IA-64 address space– it would take a long, long time!) Figure 1-7. Changing the Data Window Display Figure 1-8. The Data Window Sho

The Data Window Showingargv andenvp Strings in Hexadecimal Typing hexadecimal numbers is error-prone, and Ski provides several shortcuts to avoid it. The first is xski’s Command History, an unlabeled window pane just above the “Command” area in the Main Window. As you execute commands, they move up to the Command History. Later, you can bring th

Ski IA-64 Simulator Reference Manual 1.0L Another shortcut is the * pointer-dereference operator for indirect addressing. Type “dj 0” to jump the Data Window to location 0. Then type “dj *(r12+18)”. Ski will take the contents of r12 (9ffffffffff780, remember?), add 18 (hex) and use that as the address of the operand. The * operator fetches the contents of *(r12+18) and uses that value, 9ffffffffff938, as the address to jump to. Compare the Data Window display resulting from “dj r12+18” with the
