+ * Makefile.in (ALLDEPFILES): Add ia64-linux-nat.c and ia64-tdep.c.
+ (ia64-linux-nat.o, ia64-tdep.o): Add dependencies.
+
+ * ia64-linux-nat.c (fill_gregset): Implement.
+ (supply_fpregset, fill_fpregset): New functions.
+
+ * ia64-tdep.c (ia64_init_extra_frame_info): Revise manner in
+ which the CFM is fetched for certain frames.
+ (find_global_pointer, find_extant_func_descr): Don't use
+ partial symtabs for locating sections.
