gdb and OpenJDK

[Alexander Smundak]

I have posted a very preliminary version of the Python module
that provides the ability to walk JVM frames in GDB and show
them as Java frames (i.e., Java method names and arguments):
http://cr.openjdk.java.net/~asmundak/gdbunwind/hotspot/webrev.00/agent/src/os/linux/gdb/libjvm.so-gdb.py.html

If you want to play with it, you will need to apply my proposed GDB patch
(see the attachment to
https://sourceware.org/ml/gdb-patches/2015-02/msg00735.html),
and then follow the instructions in the source file.

I'll keep posting the new versions of this code in
http://cr.openjdk.java.net/~asmundak/gdbunwind/hotspot/webrev.01/
as they become available.
