+
+       * infptrace.c (store_inferior_registers): Move some common code out
+       to store_register, like fetch_inferior_registers & fetch_register.
+       (store_register): New function, from store_inferior_registers.
+       (fetch_inferior_registers, fetch_register): Minor code tweaks to
+       make {fetch,store}_inferior_registers and {fetch,store}_register
+       routines as similar in structure as possible.
+       (fetch_inferior_registers, store_inferior_registers): Eliminate
+       local variable numregs and just use ARCH_NUM_REGS directly.
+

        * blockframe.c: add macro USE_GENERIC_DUMMY_FRAMES to enable/disable
