complain_overflow_bitfield doesn't complain) from -2**(n-1)..2**n-1 to
-2**n..2**n. This might mean that some reloc overflows are no longer
caught, but it solves the address wrap problem for 16-bit relocs
nicely. In any case, ports that rely on complain_overflow_bitfield
for reloc overflow checking were not getting a very good check
previously. A bitfield range in a machine instruction is typically
either the signed or unsigned n bit numbers, not the overlap of these
two ranges.
not supported by the current arch, only change the name if
its contents are the same as prev_name.

i386_linux_sigtramp_saved_sp): Deleted. These all implement
Linux-specific signal trampoline detection, and should be moved to...
* i386-linux-nat.c: ... here.
* config/i386/tm-linux.h (I386_LINUX_SIGTRAMP): No need to define
this any more, since we're not enabling OS-specific code in a
OS-independent file.
(File Options): Add @cindex entries for each command-line option.
Document --epoch, --annotate, --async, --interpreter, --write,
--statistics, and --version.
* annotate.texi: Convert to a chapter. Use @value{GDBN} instead
of GDB.
* solib.c (current_sos): New function, replacing find_solib.
(find_solib): Deleted.
(free_so): New function.
(clear_solib): Call free_so, instead of writing it out.
(solib_add): Rewritten: compare the inferior's current list of
shared objects with GDB's list, and do the required loads and
unloads.
(info_sharedlibrary_command, solib_address): Don't use find_solib
to walk the list of shared libraries: call solib_add, and then
walk the list at so_list_head normally.
* objfiles.c (free_objfile): Don't call CLEAR_SOLIB, and don't
detach the core target. These tasks are taken care of elsewhere.
* target.c (remove_target_sections): New function.
* target.h (remove_target_sections): New declaration.
* solib.c (symbol_add_stub): Check whether we've already created
an objfile for this shared object first, before doing all that
work to compute section addresses, etc.
* objfiles.c (unlink_objfile): Report an internal error if objfile
doesn't occur in the object_files list.
* solib.c (special_symbol_handling): Delete argument; it's not
used.
* solib.c (SOLIB_EXTRACT_ADDRESS): New macro to extract addresses
from solib structures. Use it throughout solib.c, get rid of all
CORE_ADDR casts.
(struct so_list): Change type of lmaddr to CORE_ADDR.
(first_link_map_member): Change return value type to CORE_ADDR,
update callers.
(solib_add_common_symbols): Change parameter type to CORE_ADDR,
update callers.
(open_symbol_file_object, find_solib): Change type of lm variable
to CORE_ADDR.
Declare _rl_redisplay_after_sigwinch.
[__DJGPP__]: Don't declare term_buffer and term_string_buffer (they are
unused.)
(_rl_get_screen_size) [__DJGPP__]: Call ScreenRows and ScreenCols.
(_rl_init_terminal_io) [__GO32__]: Don't call them here. Instead, call
_rl_get_screen_size. Set terminal_name. Return 0, to be consistent with
the function's declaration.
(ding) [__GO32__]: Support visual bell by calling ScreenVisualBell.
Don't undef HANDLE_SIGNALS if __DJGPP__ is defined.
(readline_initialize_everything): [__GO32__]: Call readline_default_bindings
if HAVE_TERMIOS_H is defined.
(rl_refresh_line) [__GO32__]: Don't use this code if __DJGPP__ is defined.
is up-to-date.
(space_to_eol) [__GO32__]: Clear the screen and home the cursor.
(insert_some_chars) [__GO32__]: Don't write directly to the screen in DJGPP
versions 2.x (it doesn't work).
(delete_chars) [__GO32__]: Ditto.
(dos_print_tty_state, dos_info, _initialize_ser_dos): Convert
to ISO C. Use ATTRIBUTE_UNUSED to avoid compiler warnings.
(dos_info): Avoid compiler warning when printing a ptrdiff_t.
