* config/mn10300/tm-mn10300.h (D0_REGNUM, A0_REGNUM, MDRQ_REGNUM,
MCRH_REGNUM, MCRL_REGNUM, MCVF_REGNUM): New definitions.
(enum movm_register_bits): New enum.
* mn10300-tdep.c (set_movm_offsets): Use symbolic names for the
bits, not hex literals. Handle the `other', `exreg0', and
`exother' bits. Correct handling of `exreg1': it saves r4, r5,
r6, and r7, not r2, r3, r4, and r5.
(saved_regs_size): New function.
(mn10300_frame_chain, mn10300_frame_saved_pc): Use it, instead
of computing the same thing inline, incorrectly.
stuff out into mn10300_pop_frame_regular, and use
generic_pop_current_frame. This lets us share code, and also
makes this function's prototype match that expected by gdbarch.
Make this function static.
(mn10300_pop_frame_regular): New function.
(mn10300_gdbarch_init): Register mn10300_pop_frame as the
gdbarch's pop_frame method.
* config/mn10300/tm-mn10300.h (POP_FRAME): Delete definition.
(mn10300_pop_frame): Delete declaration.

Make these functions static; they should only be visible to the
outside world as gdbarch methods.

Delete definitions. We register gdbarch methods for these now.
(struct frame_info, struct type, struct value): Delete forward
declarations of these types; they're no longer necessary, since we
don't have function declarations here any more.
* mn10300-tdep.c: #include "arch-utils.h", to get declarations for
some default gdbarch methods.
(mn10300_store_struct_return): Return void, as expected by
gdbarch.
(mn10300_init_extra_frame_info): Take initial `fromleaf' argument,
as expected by gdbarch.
(mn10300_frame_init_saved_regs): Provide dummy definition for
this, as required by gdbarch.
(mn10300_gdbarch_init): Add mn10300_call_dummy_words, as expected
by gdbarch. Register gdbarch methods or values for all the stuff
removed from tm-10300.h, listed above.
Convert mn10300, MIPS and powerpc/rs6000 targets to use
BREAKPOINT_FROM_PC
Delete global variable memory_breakpoint_size. Use BREAKPOINT_FROM_PC
instead.

(D2_REGNUM, D3_REGNUM, A2_REGNUM, A3_REGNUM): Define.
* mn10300-tdep.c (fix_frame_pointer): New function.
(set_movm_offsets): Use register number macros instead of
hard-coded constants.
(mn10300_analyze_prologue): Fix to handle redefinition of FP_REGNUM.
(mn10300_frame_chain): Fix to handle redefinition of FP_REGNUM;
use register number macros instead of hard-coded constants;
add missing parameter to call of mn10300_analyze_prologue.
(mn10300_frame_saved_pc): Use register number macros instead of
hard-coded constants.
for mn10300_analyze_prologue.
(mn10300_analyze_prologue): Simplify by factoring out common code.
Fix bugs in setting frame address for optimized code.
Use read_memory_nobpt instead of target_read_memory.
* mn10300-tdep.c: wrote/fixed implementations of
mn10300_frame_chain, mn10300_init_extra_frame_info,
mn10300_frame_saved_pc
* config/mn10300/tm-mn10300.h: redefine INIT_EXTRA_FRAME_INFO
and INIT_FRAME_PC macros
Backtracing starting to work correctly.
