* arch-utils.c (default_elf_make_msymbol_special,
default_coff_make_msymbol_special): New functions.
* arch-utils.h (default_elf_make_msymbol_special,
default_coff_make_msymbol_special): Export.
* elfread.c (elf_symtab_read): Compile use of
ELF_MAKE_MSYMBOL_SPECIAL unconditionally because it is now
multiarched.
* coffread.c (coff_symtab_read): Ditto, for
COFF_MAKE_MSYMBOL_SPECIAL.
* arch-utils.c (generic_register_virtual_size): New function.
* arch-utils.h: Export generic version of register_virtual_size.
* gdbarch.sh (REGISTER_VIRTUAL_SIZE): Use new function as default.
* gdbarch.c: Regenerate.
* s390-tdep.c (s390_use_struct_convention): New function.
(s390_gdbarch_init): Register it as the S/390's
USE_STRUCT_CONVENTION method. Register
generic_cannot_extract_struct_value_address as our
EXTRACT_STRUCT_VALUE_ADDRESS method.
* arch-utils.c (generic_cannot_extract_struct_value_address): New
function.
* arch-utils.h: Add corresponding prototype.
* arch-utils.h (generic_in_function_epilogue_p): Declare extern.
* breakpoint.c (watchpoint_check): Add test whether the pc is
currently in the epilogue of a function.
* gdbarch.c: Autogenerated from gdbarch.sh.
* gdbarch.h: Ditto.

* arch-utils.c (default_prepare_to_proceed)
(generic_prepare_to_proceed): Added new functions.

* gdbarch.c: Regenerated.
* gdbarch.h: Regenerated.
* inferior.h: Added get_last_target_status() declaration.
* infrun.c (get_last_target_status): Added new function.
(handle_inferior_event): Saves last pid and waitstatus, which will
get returned by get_last_target_status().
* hppa-tdep.c (prepare_to_proceed): Added comment stating that
prepare_to_proceed() is potentially redundant since
default_prepare_to_proceed() has been added.
* linux-thread.c (prepare_to_proceed): Ditto.
* lin-lwp.c (prepare_to_proceed): Ditto.
* m3-nat.c (prepare_to_proceed): Ditto.
arch-utils.{h,c}. The ``set architecutre'' and ``set endian''
commands (part of the move) were implemented to use add_set_enum_cmd()
so that ``set architecture <tab>'' works.
