Fix 'gdbarch already exists' test by comparing os_ident as well.
As the last action, invoke OS abi_handler if installed.

of an array sized by REGISTER_BYTES.
(examine_prologue): Accept a pointer to an array of CORE_ADDR,
instead of the defunct struct frame_saved_regs. Recognize new

destination of a frame store when parsing the prologue (so long
as it's on the stack).

(sparc_frame_find_saved_regs): Accept a ptr to an array of CORE_ADDR
instead of the defunct struct frame_saved_regs.

supply_register. Provide 4-byte offset to compensate for diff
between size of the prgreg_t elements on a 64-bit host and size
of the registers for a 32-bit target. Fill all inaccessible regs
with zero so they won't keep being requested again and again.

work for configs where build/host/target are the same.

Added monitor flags MO_NO_ECHO_ON_SETMEM (don't expect echo on
setmem command), MO_RUN_FIRST_TIME (if command to start process
running on target is different from one to continue execution),
MO_HEX_PREFIX (if addresses from monitor have a "0x" prefix).
* monitor.c,parse.c,sparc-tdep.c:
Don't require strings in the registers array. This is to allow
NULLs to be place holders in the tm-*.h file so that only minor
changes are needed when a new processor is introduced (eg, one
without floating point).

here. Get it right for flat frames.
* sparc-tdep.c (sparc_frame_chain): Instead of returning
meaningful value for ->frame field, just return dummy value.
This change is needed because the old code didn't deal with mixed
flat and non-flat frames.
* sparc-tdep.c (sparc_pop_frame): Write SP_REGNUM from
frame->frame, don't go through saved regs for this.
* sparc-tdep.c: Move guts of skip_prologue to new function
examine_prologue. Check for flat prologue and set is_flat.
Provide the caller with the information about what is saved where
if desired.
(skip_prologue, sparc_frame_find_saved_regs): Call examine_prologue.
* sparc-tdep.c: Replace union sparc_insn_layout and anonymous
union in isannulled, which won't work on a little-endian host,
