a write_register to a pseudo-reg. Target_store_pseudo_register

in their system headers symbols with global scope that go by those
names.

set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.
(struct gdbarch): Delete members d10v_make_daddr,
d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(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.
(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
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.
include of "serial.h".
* Makefile.in (remote_utils_h): Update.
* monitor.h (struct serial): Declare as opaque. Remove include of
"serial.h".
(struct monitor_ops): Replace serial_t with `struct serial *'.
* 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.

(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

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,

selected one.

sigtrapped lwps to handle next.

(Host Definition): Document that much of this chapter is obsolete.

up a target architecture.

(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.
