* Patches from Jeffrey Law <law@cs.utah.edu>.
+ * gdb/hppa-tdep.c (frame_chain_valid): If "use_unwind" is true, then
+ use unwind descriptors to determine if the frame chain is valid.
* gdb/hppa-tdep.c (find_dummy_frame_regs): Rework so that
it does not assume %r4 is the frame pointer.
* gdb/hppa-pinsn.c (print_insn): Handle 'r' and 'R' for break, rsm,
