of reading/writing registers that are shorter than REGISTER_TYPE.
* (value_from_register): Install H8500 specific code to return
proper value when register is being used as a pointer.
* h8500-tdep.c: Remove extra defines of NUM_REGS.
(h8500_skip_prologue): Use correct lengths for LINK instructions.
(FRAME_CHAIN): Change name to h8500_frame_chain. Rewrite code to
chain frames properly by combining frame pointer with T reg.
(init_extra_frame_info): Delete. It's now a macro.
(frame_args_address): Don't add PTR_SIZE. Stack args are already
offset by the correct amount off of the frame pointer.
(register_byte): Delete. It's now a macro.
(register_raw_size, register_virtual_size): Delete. Replaced by
common routine h8500_register_size, cuz there's no difference
between the raw & virtual sizes on this machine.
(register_convert_to_raw, register_convert_to_virtual): Delete,
cuz there's no difference between the raw & virtual forms.
Replaced by memcpy in tm file.
(register_virtual_type): Rename to h8500_register_virtual_type.
Get rid of pointer pseudo-regs, use _REGNUM with all reg names.
(_initialize_h8500_tdep): Get rid of crock to ensure that GDB &
emulator have same reg offsets. This is all handled in the
simulator code now.
(h8500_trapped_internalvar): New routine to detect references to
convenience vars acting as pointer pseudo-regs.
(h8500_value_trapped_internalvar): Conjure up value of pointer
pseudo-regs.
(h8500_set_trapped_internalvar): Convert set value in real
register references.
infcmd.c (read_pc, write_pc): Add h8500 specific code to handle
code segment register.
infrun.c (proceed): Simplify. Call write_pc instead of doing it
by hand.
(wait_for_inferior): Add h8500 specific code to add stack segment
when reading SP register.
remote-sim.c (fetch_register): Spacing.
tm-h8500.h: #define GDB_TARGET_IS_H8500 to make it easier to
detect cruft. Redo all register manipulation stuff. Get rid of
pointer pseudo-regs. (INIT_EXTRA_FRAME_INFO): Adds stack segment
to frame pointer. (IS_TRAPPED_INTERNALVAL,
VALUE_OF_TRAPPED_INTERNALVAR, SET_TRAPPED_INTERNALVAR): Use these
to create internal vars for pointer pseudo-regs.
get linked to nm.h, xm.h, and tm.h respectively by configure,
moved to appropriate config/<cpu> subdirectory.
* nm-sysv4.h, xm-sysv4.h, tm-sysv4.h, tm-sunos.h, nm-trash.h:
Native, host, and target files that are common across more than
one cpu architecture and included by one of the configured
native, host, or target files, get moved to config directory.
