Figure 5-1. xski’s Program Window Showing IA-64 Assembly Language Code

pm

Display the program being simulated in its source code form with the assembly language translation mixed in, as shown in Figure 5-2.The source code display is for your convenience only; you cannot interact with the source code, e.g., modify the source code, click on a variable name to see its value in the Data Window, and so on. The source code is not embedded in the executable ﬁle. Instead, the compiler and linker place into the executable ﬁle a record of the location and ﬁlename of the source code. The source code ﬁle must be available to Ski in the location recorded in the executable ﬁle. In practice, this means you will want to run xski or ski from the directory where the program was compiled. (See Section 3.5, “The Program Window” for more information on source code compilation.) This command is valid for IA-64 code only. The mnemonic stands for “program display mixed”.
