ser-bsd.o from XDEPFILES. All the magic is now handled in
configure.in.
entire breakpoint chain and print only the first entry that needs to
be printed and needs to be stopped for. Fixes problems with printing
of multiple breakpoints with different conditions.
* breakpoint.c (print_it_done): Renamed from print_it_noop as it
effectively stops printing of the breakpoint chain.

(bpstat_{alloc,stop_status}): Set print_it field.
* breakpoint.c (bpstat_stop_status): Use catch_errors when
evaluating watchpoint condition, via new function watchpoint_check.
Also stop if watchpoint disabled due to leaving its block.
* breakpoint.c (enable_breakpoint): Don't enable watchpoint if it
went out of scope.

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.

Get rid of pointer pseudo-regs, use _REGNUM with all reg names.

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.
m88k, mips, none, ns32k, pa, pyr, romp, rs6000, sparc, tahoe, vax,
z8k}: New directories to hold cpu specific configuration files.
Naming follows gcc convention.
* config/{*.mt, *.mh}: All target and host makefile fragment
config files moved to an appropriate config/<cpu> subdirectory.
* nm-*, xm-*, tm-*: All native, host, and target files, which
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.
* Makefile.in (INCLUDE_CFLAGS): Add -I${srcdir}/config to
pick up native, host, or target include files moved to one of
the config subdirectories, and that are included by other files.
* Makefile.in (alldeps.mak): Modify to account for new config
directory structure.
* alldeps.mak, depend: Update for new config directory structure.
* config/*/[ntx]m-*.h: Modify all files that include other
[ntx]m-*.h files to use path relative to gdb/config. I.E.
"a29k/tm-ultra3.h" includes "a29k/tm-29k.h" rather than just
"tm-29k.h".
* remote-eb.c (tm-29k.h): Include a29k/tm-29k.h.
* mipsread.c (tm-mips.h): Include mips/tm-mips.h.
* i860-pinsn.c (tm-i860.h): Include i860/tm-i860.h.
* configure.in: Default gdb_host_cpu to host_cpu, and remap
the ones where the default is not unique or different than the
config subdirectory name. Similarly, handle gdb_target_cpu.
Modify configure.in as appropriate to make use of gdb_host_cpu
and gdb_target_cpu to find makefile fragments and make links.
