(read_memory_region, get_descriptor, display_descriptor)
(go32_sldt, go32_sgdt, go32_sidt): New functions.
(top-level): Include ctype.h, utsname.h, dos.h, and go32.h. Ifdef
away `disable' from dos.h, since breakpoint.h defines an enum
member of the same name, and GCC 2.7.2 barfs.
(_initialize_go32_nat): Provide new commands dos-sysinfo, dos-ldt,
dos-gdt, and dos-idt, all of them in the "info" class
Testing: I tested on native Red Hat Linux 7 using gcc 3.0.
The "info float" command exercises print_i387_value.

* i387-tdep.c (print_i387_value): Fix pointer glitch.

(select_event_lwp_callback): Likewise.
(cancel_breakpoints_callback): Bail out early if LP is the event
LWP. Add comment about backup up breakpoints. Fix formatting and
debug message.
(select_event_lwp): Make solely repsonsible for switching event
LWP. Fix formatting and remove bogus "ERROR" debug message.
Don't backup breakpoints from here.
(lin_lwp_wait): Don't touch LP->status, let select_event_lwp
handle that. Only call select_event_lwp if we're not waiting for
a specific LWP, i.e. when PID == -1. Backup breakpoints from here.
* lin-lwp.c: Prevent thread starvation by using a monte carlo
method to choose which of several event threads to handle next.
(stop_wait_callback): Defer pushback of breakpoint events until
later; add SIGTRAP events to the queue of unhandled events.
Keep calling waitpid until SIGSTOP retrieved. If more than one
non-SIGSTOP event is retrieved, push them back onto the process
queue using kill.
(count_events_callback, select_singlestep_lwp_callback,
select_event_lwp_callback, cancel_breakpoints_callback,
select_event_lwp): New functions. Implement monte carlo method
for selecting which of several SIGTRAP threads to handle next.
Push back the breakpoint event for all threads other than the
selected one.
(lin_lwp_wait): Call select_event_lwp to decide which of several
sigtrapped lwps to handle next.
(resume_callback): Disable code that attempts to handle
step_resume breakpoints. Let core gdb handle this.

d10v_write_sp, d10v_write_fp, d10v_read_fp,
d10v_push_return_address): Call the functions d10v_make_daddr,
d10v_make_iaddr, d10v_convert_iaddr_to_raw, and
d10v_convert_daddr_to_raw, not the global macros D10V_MAKE_DADDR,

D10V_CONVERT_DADDR_TO_RAW.
structure and not macros.
(Host Definition): Document that much of this chapter is obsolete.
(Target Architecture Definition): Update list of files that make
up a target architecture.
(Coding): Update.
(read_partial_die): Delete fourth argument; we return this info in
the struct partial_die_info object itself now.
(dwarf2_build_psymtabs_hard, scan_partial_symbols): Use the
has_pc_info field of the partial die struct, rather than passing a
variable by reference to read_partial_die.
code in loop condition. This seemed to be trying to round
info_ptr up to the next four-byte boundary, but that's not what it
actually did. If we discover the problem the old code was really
trying to address, we can fix it properly.
* thread-db.c (attach_thread): Check for TD_THR_ZOMBIE in addition
to TD_THR_UNKNOWN when looking for defunct zombie threads.
(thread_db_thread_alive): Ditto.
(find_new_threads_callback): Ditto.
(get_hex_word): Don't use HOST_BYTE_ORDER.
(array_fetch_registers): Add variable ``reg''. Use
store_unsigned_integer to byte-swap the register. Delete unused
local ``regs''.
* infrun.c (handle_inferior_event): Replace prev_pc test in all
calls to bpstat_stop_status (removed in 1999-09-24). This test
helps distinguish stepping over a breakpoint trap from stepping
thru a jump to the instruction after a breakpoint trap.
(handle_inferior_event): Don't bother writing the PC if
DECR_PC_AFTER_BREAK is zero (optimization).
* breakpoint.c (bpstat_stop_status): Add comment explaining the
purpose and usage of the "not_a_breakpoint" argument in computing
the breakpoint address.
* monitor.c (setmem_resp_delim_pattern): New regexp pattern.
(setreg_resp_delim_pattern): Likewise.
(setmem_resp_delim_fastmap): New buffer.
(setreg_resp_delim_fastmap): Likewise.
(monitor_open): Initialize above regexp if they are defined.
(monitor_write_memory): Use regexp to check the result of write.
(monitor_store_register): Likewise to check result of register set.
