+ Make linux_get_siginfo_type `type *' unique.
+ * linux-tdep.c (linux_gdbarch_data_handle, struct linux_gdbarch_data)
+ (init_linux_gdbarch_data, get_linux_gdbarch_data): New.
+ (linux_get_siginfo_type): New variable linux_gdbarch_data. Initialize
+ it. Use linux_gdbarch_data->siginfo_type as a persistent storage.
+ (_initialize_linux_tdep): New.
+
+2010-08-31 Jan Kratochvil <jan.kratochvil@redhat.com>
+
Code cleanup.
* defs.h (find_memory_region_ftype): New typedef.
(exec_set_find_memory_regions): Use it.
