* gdbarch.c Include "gdb_obstack.h".
(struct gdbarch): Add an "obstack".
(alloc_gdbarch_data): Allocate the gdbarch data using
GDBARCH_OBSTACK_CALLOC.
(free_gdbarch_data): Delete function.
(gdbarch_obstack_zalloc): New function.
(gdbarch_free): Free the obstack, do not call free_gdbarch_data.
Assert that the architecture is not initialized.
(gdbarch_alloc): Allocate an obstack, allocate the architecture
vector from the obstack.
(alloc_gdbarch_data, init_gdbarch_swap): Allocate memory using the
architecture obstack.
(GDBARCH_OBSTACK_CALLOC, GDBARCH_OBSTACK_ZALLOC): Define.
(set_gdbarch_data): Assert that the data is not initialized.
(struct gdbarch_data): Delete member "free".
(register_gdbarch_data): Do not initialize "free".
* gdbarch.h, gdbarch.c: Re-generate.
