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.
(get_specific): If the the architecture doesn't match, fail.

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.
* eval.c (evaluate_subexp_with_coercion): Add call to
check_typedef, to handle typedeffed vars correctly.
* gdb.base/printcmds.c: Add typedeffed arrays.
* gdb.base/printcmds.exp (test_print_typedef_arrays): New
procedure to test arrays that are typedef'd.
Add support for a variable object that tries to evaluate itself in
the currently selected frame, rather than in a fixed frame.
* wrapper.c,h (gdb_parse_exp_1): Added a wrapper for
gdb_parse_exp_1.
* varobj.h: Added USE_CURRENT_FRAME to varobj_type & changed def'n
of varobj_create.
* varobj.c (varobj_list): Return type indicates whether the
variable's type has changed (for current frame variables).
(varobj_update): Handle the case where the variable's type has
changed.
(delete_variable_1): Allow for deletion of variables that have not
been installed yet.
(new_root_variable): Initialize use_selected_frame variable.
(value_of_root): This is where most of the work to handle "current
frame" variables was added. Most of the complexity involves
handling the case where the type of the variable has changed.
(varobj_create): Add a "type" argument, to tell if the
variable is one of these "current frame" variables. Also protect
call to parse_exp_1 from long jumping.
* mi-var-block.exp: The error report from varobj_create changed
since I am now trapping parse_exp_1 errors. Change the tests to
match the new error message.
* mi-var-child.exp: Ditto.
* mi-var-cmd.exp: Ditto.
* lib/gdb.exp: Fix the gdbtk_start routine to correctly find all
the library directories.
* gdbtk-varobj.c (variable_create): Pass the correct
"how_specified" flag to the varobj_create routine.
