sizeof_cooked_registers and sizeof_cooked_register_valid_p.

register cache and then assign that to sizeof_raw_registers. Set
sizeof_raw_register_valid_p to sizeof_cooked_register_valid_p

i387_supply_register).
* blockframe.c (sigtramp_saved_pc): Use
builtin_type_void_code_ptr, not builtin_type_void_data_ptr (we are
extracting the PC). Use TYPE_LENGTH (builtin_type_void_code_ptr)
instead of (TARGET_PTR_BIT / TARGET_CHAR_BIT).
* frame.c (get_prev_frame): Cleanups. Eliminate redundant tests
for a NULL NEXT_FRAME. Simplify fromleaf initialization. Add
more comments. Zap dead code.

selected frame up, such that it is also used if a target provides
multi-arch definitions of these functions.

* dummy-frame.h (dummy_frame_register_unwind): Rename
generic_call_dummy_register_unwind.
* hppa-tdep.c: Add new functions replacing macro bodies from
config/pa/tm-hppa.h. These function will be used to initialize
the gdbarch structure. Import some comments from tm-hppa.h,
and place them where appropriate, to avoid loosing them when
we cleanup this file.

(_initialize_printcmd): Do not create disassemble command here.
* cli/cli-cmds.c (disassemble_command): New function. Implements
disassemble command.
(init_cli_cmds): Create disassemble command here instead.
* gdb.asm/asm-source.exp: Adjust patter to new disassembler routine
which explicitly prints the zero offset as "+0".
* hppa-tdep.c (hppa_gdbarch_init): New function.

(_initialize_hppa_tdep): Register the hppa gdbarch init function and
tdep structure dumper.

until the multi-arching conversion has partially been completed.
* valops.c (value_assign): Merge lval_register case into
lval_reg_frame_relative. Use frame_register and

write_register_bytes. After flushing the register cache, try to
re-select the selected frame.

(print_float_info): Print registers in float_reggroup.
(print_vector_info): Print registers in vector_reggroup.

all_reggroup. Otherwize, print registers in general_reggroup.
(registers_info): Rewrite. Add support for register groups.
Eliminate a goto.

ages.
(symtab_symbol_info): Remove eons old ifdeffed out code.
(_initialize_symtab): Remove prehistoric disabled 'info methods'
command.
* f-exp.y: Add missing semi-colons.
