HP WDB 5.7 Release Notes

Announcement

HP Wildebeest Debugger (WDB) 5.7 is an HP-supported implementation of the open source

debugger GDB. It supports source-level debugging of programs written in HP C, HP aC++, and

Fortran 90 on Itanium®-based systems running HP-UX 11i v2 or HP-UX 11i v3, and HP 9000

systems running HP-UX 11i v1, HP-UX 11i v2, or HP-UX 11i v3.

What is New in This Version of HP WDB for Integrity Systems

The following new features are introduced in this version of HP WDB for Integrity systems:

Enhanced Support for Debugging Optimized Code

HP WDB 5.7 provides the following enhanced support for debugging optimized code:

• “Printing Values of the Local Variables in Optimized Code Built With –g” (page 7)

• “Support to Prevent the Debugged Program from Stopping at Instructions that are Predicated

False ” (page 8)

Printing Values of the Local Variables in Optimized Code Built With –g

HP WDB 5.7 enables you to examine local variables and formal parameters in programs that are

compiled with optimization levels above +O1 (available for compiler versions A.06.15 and

later). This feature is available for live processes, and core files that are created by optimized

code. Limited stepping operations in the optimized code continue to be supported with no

additional enhancements.

The debugger reports the values of the variables in the optimized source code. However, as a

result of optimization, there are code locations where the value of the local variables may not be
