Ski IA-64 Simulator Reference Manual 1.0L

Unable to open console window

Your system-mode program tried to open a console with the appropriate Simulator System Call but Ski wasn’t able to spawn the corresponding xterm program. First, verify that environment variable DISPLAY is set to the proper hostname:displaynumber string. If this does not help, perhaps there is no xterm available via your PATH environ- ment variable? Perhaps you have hit the process limit or used all the pseudo-tty devices on your Linux system? See “System-ModeIA-64 Programs” on page 6-2.

Unaligned Data fault

An attempt was made to access data on an unnatural boundary. Two-byte quantities must be on addresses evenly divisible by two; four-byte quantities must be on addresses evenly divisible by four, and so on. See “Misaligned Data Access Trap” on page 6-3and “Interruptions” on page 7-1.

Unexpected end of file

You are trying to restore a saved simulator state and either the save file is corrupt or Ski is broken. See “Saving and Restoring the Simulator State” on page 8-8.

unrecognized option %s

You specified a command line option that Ski doesn’t understand. Different varieties of Ski ( xski, ski, and bski) understand different flags. See “Command Line Flags” on page 2-4.

Unrecognized symbol name: %s

You tried to refer to a symbol in an expression but Ski doesn’t know about that symbol. Perhaps you mis-typed it? Or perhaps it is a program-defined symbol in a file that wasn’t compiled with debugging symbol generation enabled (the -gflag on many compilers)? Or perhaps you referred to an IA-64 register using a mnemonic that Ski doesn’t recog- nize? See “Symbolic Arguments” on page 4-4, “Symbol Table Commands” on page 8-8,and Appendix B, “Register Names”.

unsupported DOS int 21 function %02x%02x

Your IA-32 application-mode program tried to invoke an MS-DOS function that Ski doesn’t emulate. The first hexa- decimal number is the MS-DOS function code and the second number is the sub-function code. See “Application- Mode IA-32 Programs” on page 6-1and “MS-DOS Application Environment” on page 7-3.

Unsupported SSC: %d

Your IA-64 system-mode program invoked a Simulator System Call that Ski doesn’t support. Either your program has a bug or Ski is broken. See “System-ModeIA-64 Programs” on page 6-2.

unsupported system call %d

Your IA-64 application-mode program tried to invoke an Linux system call that Ski doesn’t emulate. See “Linux Application Environment” on page 7-1and “Application-ModeIA-64 Programs” on page 6-1.

Usage: %s [options] [file [args]]
