Compatibility
There are no compatibility issues. (Note that Aries itself is a key product in binary
compatibility between PA-RISC and Itanium-based.)
Performance
The experimental dynamic translator significantly improves the performance of the
emulated application. From the initial measurements it has been observed that the
overall Aries performance, with the experimental dynamic translator turned on,
increases by 20% on an average. This increase may vary based on the nature of the
emulated PA-RISC application.
Documentation
The manpage for Aries, Aries (5), has been changed.
For further information, see the white paper, “Compatibility Mode on Itanium-based
HP-UX: A Developer Perspective,” available at

Obsolescence
Not applicable.
Debugging
This section includes the following topics:
• “Absolute Debugger (adb)” on page 207
• “HP Kernel Debugger (KWDB)” on page 208
• “HP Wildebeest Debugger (WDB)” on page 209
Absolute Debugger (adb)
The adb command executes a general-purpose debugging program, the Absolute
Debugger, that is sensitive to the underlying architecture of the processor and operating
system on which it runs. It can be used to examine files and provide a controlled
environment for executing HP-UX programs.
Summary of Change
Absolute Debugger incorporates the following new features:
• Support for Lazyfp
• Support for Dual pdir
• Support for debugging MxN threads in a process/core
