• Serial debugging of a parent and child process.
• Support for Parallel Processing limited to pthread parallelism, but not the compiler
generated parallelism, for example, with directives.
• Implementation of ask mode for set follow-fork-mode.
• Support for setting breakpoints using shared library name.
• Support for core file commands packcore, unpackcore, getcore, dumpcore
and info rtti address.
• On PA-RISC systems, sanity check for core files dumped by hardware generated
signals can be performed. HP WDB can detect and warn the user about certain
cases of corrupted core files.
• Inline support is on by default on Integrity systems. On PA-RISC, the inline support
is still off by default.
• For PA 64-bit applications, WDB can step into shared library bind-on-reference
calls. This support is available for PA 32-bit as well.
• Interception of synchronous signals used by sigwait(), sigwaitinfo() and
sigtimedwait() functions. These signals are displayed by WDB just like
asynchronous signals but are always passed to the debugger whether [nopass]
is set or not.
• Support for debugging hardware watchpoints and shared libraries.
• For PA 64-bit applications, WDB can step into shared library bind-on-reference
calls. This support is available for PA 32-bit as well.
• Implementation of -mapshared option to suppress mapping all the shared libraries
in a process private.
• Support for deferred breakpoints on dlopened and shl_loaded libraries with
stripped main program.
• Additional support for procedural breakpoints.
• C99 variable arrays implemented on Integrity systems. This support is available
on PA-RISC as well.
• The show envvars command can be used to print information on environment
variables supported by WDB.
• Support for handling __fpreg data type.
• Support for making changes to the program when debugging without having to
re- compile or re-link it.
• Hardware breakpoints on Integrity systems.
• Support for debugging PA-RISC Applications on Integrity systems.
• Unwinding Java stack frames on Integrity systems. The 64-bit version of gdb can
unwind through Java stack frames using the shared library in the Java product.
The 64-bit library is part of the JDK 1.4.2.10 and JDK 1.5.0.03 products.
• Enhanced nexti and stepi commands. The WDB nexti and stepi commands,
prints the assembly instruction along with the next source line.
