(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer. This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.

methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are. Say that addresses
are 32 bits long. Register the address_to_pointer and
pointer_to_address conversion functions. Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible. Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
gdbarch_d10v_convert_iaddr_to_raw.

"serial.h".

* monitor.c (monitor_desc): Ditto.
(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.
2001-07-06 Michael Chastain <chastain@redhat.com>
* i387-tdep.c (print_i387_value): Fix pointer glitch.

(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_MAKE_IADDR, D10V_CONVERT_IADDR_TO_RAW, and
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.

and replace it with a relatively simple test in resume.
(resume): Replace thread_step_needed logic with a test for
stepping, breakpoint_here_p and breakpoints_inserted.
Move CANNOT_STEP_BREAKPOINT logic to after thread_step logic.
(proceed): Discard thread_step_needed logic.
(wait_for_inferior, fetch_inferior_event, handle_inferior_event):
Discard thread_step_needed logic.
* remote-rdi.c (arm_rdi_wait): Fix return type in prototype.

* configure.in: include nlist.h when checking for member som_addr
in struct so_map.

"tm.h".
* gdbarch.h, gdbarch.c: Regenerate.
* defs.h (GDB_MULTI_ARCH_TM): Rewrite definition.
* infrun.c (context_switch): New function. Abstract the operation
of saving and restoring infrun's state when switching threads.
(handle_inferior_event): Normalize the handling of the 'thread hop'
event (when the wrong thread hits a thread-specific breakpoint,
and we need to solo-step that thread past the breakpoint).
Call keep_going, instead of target_resume. Handle the subsequent
singlestep-trap as a normal event instead of just resuming.
(EXTRACT_STRUCT_VALUE_ADDRESS): Change to a function with
predicate.
* gdbarch.h, gdbarch.c: Regenerate.
* values.c (value_being_returned): Change the reference to
EXTRACT_STRUCT_VALUE_ADDRESS_P to a function call.

(remote_check_symbols): New function. Implement qSymbol packet,
allowing target to request symbol lookup service from gdb.
(remote_open_1, remote_async_open_1): Call remote_check_symbols,
allowing symbol lookup from exec_bfd on connection to target.
(remote_new_objfile): New function. Catch new objfile notifications
from shared library module, and call remote_check_symbols.
(_initialize_remote): Hook remote_new_objfile into the shared
library notification chain. Add "set remote symbol-lookup" command.
* gdbthread.h (struct thread_info): Add new fields:
current_line, current_symtab, step_sp, for saved infrun state.
* thread.c (save_infrun_state, load_infrun_state): Save and
restore current_line, current_symtab, and step_sp.
(add_thread): Rather than adding assignments to initialize
the new fields, just use memset (tp, 0, sizeof (*tp).
This way future new fields will not be overlooked.
* infrun.c (handle_inferior_event): Save and restore save_sp,
current_line, and current_symtab when switching threads.
(line_completion_function): If we are completing on locations,
back up the start of word pointer past all characters which can
appear in a location spec.

the completion function for the "print", "inspect", "call", and
"disassemble" commands.
(top-level): #include "completer.h".
* infcmd.c (_initialize_infcmd): Make location_completer be the
completion function for the "go", "jump", and "until" commands.
(top-level): #include "completer.h".
* breakpoint.c (delete_breakpoint): Pass mark_inserted to
remove_breakpoint, so that the subsequent test for
bpt->inserted will succeed, and duplicates will be fixed up.
a little more portable.
Don't use shell's echo command to put strings containing
escaped characeters into a file -- different flavors of /bin/sh
require differnt levels of escaping. Use cat <<EOF instead.
Our internal field separator is a colon. Change all
commands which assume it is a space.

* mips-tdep.c (mips_gdbarch_init) <MIPS_ABI_N32>: Set up the
disassembler info in tm_print_insn_info as appropriate for the N32
ABI. Force N32 ABI to be the default if the CPU is R8000 or
R10000.
* configure.tgt (mips*-sgi-irix6*): Map to irix6.
* configure.host (mips*-sgi-irix6*): Ditto.
stopped due to a Ctrl-C as well as breakpoints.

* gdbarch.c (alloc_gdbarch_data, init_gdbarch_data): Delete
declarations and definitions.
(check_gdbarch_data): New function, and declaration.
(gdbarch_alloc): Don't call alloc_gdbarch_data; leaving the fields
zero is good enough.
