HP WDB 6.2 Release Notes (5900-1472; January 2011)

pre-loaded, the debugger obtains the thread-error information in the batch mode
for exec-ed application.
• HP WDB cannot execute both batch mode thread check and batch mode heap
check together. If the rtcconfig file has both entries, then batch heap check
overrides the batch thread check.
Mixed Mode Debugging
The following are not supported for mixed mode debugging:
• Placing a breakpoint on a PA-RISC library.
• Listing the arguments (using the info args command) for a selected PA-RISC frame
during corefile debugging. Alternatively, the disassembly instructions or runtime
conventions can be examined to identify the locations of the arguments and the
values at these locations can be displayed using the print or x command.
• Printing the local variables of the selected frame (using the info locals command)
for a selected PA-RISC frame during corefile debugging. Alternatively, the disassembly
instructions can be examined to identify the locations of the arguments and the values
at these locations of the local variables can be displayed using the print or x
command.
• Executing the backtrace_other_thread command for a frame belonging to a
PA-RISC library.
• Executing the maint info unwind command for PA addresses.
• Printing the description of the type of expression or data type (using the ptype
command) on a PA-RISC symbol.
Debugger Support for Optimized Code
On HP 9000 systems for 32-bit and 64-bit applications, printing of local variable values
may be inaccurate for +O1 and higher optimizations.
NOTE: HP WDB 6.1 and later versions contains limited debugging support for optimized
code of 32-bit applications on HP 9000 and even more limited support for debugging
optimized code (DOC) for 64-bit applications on HP 9000 systems. Additionally, the
debugging support becomes limited as higher levels of compiler optimization are used.
