# Progress #
* TCWG-1159, New design of GDB/GDBserver target description. [3/10]
Update patches to address review comments. Commit three patches.
Need to post V3.

* TCWG-561, Handle unavailable memory during frame unwinding. [2/10]
Think about the plan.

* Upstream patches review. [3/10]
** Review IBM kernel-awareness patches.
** Review sparc64 adi patch.
** Review Alan's patch on removing MAX_REGISTER_SIZE. Evaluate other
better but expensive approach.

* Misc, [2/10]
Write a STL container allocator which uses stack instead of heap.
Underestimate the complexity of C++. Need to replace some std::vector
with my vector with stack_allocator in GDB. It should be also useful
to Alan.
