(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.

functions.
(regno_mapping, sig_map, excepn_map): Add braces around inner
initializers.

fix code which mixed signed with unsigned.
(go32_resume): Use TARGET_SIGNAL_LAST instead of -1.
(go32_wait): Initialize INT3_addr.
(go32_fetch_registers): Extend all FP registers that are shorter
than 4 bytes to 32 bits. Support 32 standard FP registers defined
on config/i386/tm-i386.h.
(store_register): Support 32 FP registers.
(go32_create_inferior): Don't crash if handed a NULL pointer
instead of exec file name.
(ignore): Remove unused function.
(go32_insert_hw_breakpoint): Remove unused variables.
(init_go32_ops): Set value of processing_gcc_compilation to 2.
* gnu-nat.c: Fix the formatting where indent misinterpreted `&' as
a binary operator.
(gnu_attach): Change error message for missing
argument to be identical to the corresponding message in
`inftarg.c'. This makes the testsuite happy.
* elf32-mips.c (mips_elf_next_relocation): Rename from
mips_elf_next_lo16_relocation, and generalize to look
for any relocation type.
(elf_mips_howto_table): Make R_MIPS_PC16 pcrel_offset.

(mips_rtype_to_howto): Likewise.
(mips_elf_calculate_relocation): Handle new relocs.
(_bfd_mips_elf_relocate_section): REL_HI16/REL_LO16 relocs
are paired. The addend for R_MIPS_GNU_REL16_S2
is shifted right two bits.
In gas/:
* config/tc-mips.c (mips_ip): Don't put stuff in .rodata
when embedded-pic.
* config/tc-mips.c (SWITCH_TABLE): The ELF embedded-pic
implementation doesn't have special handling for switch
statements.
(macro_build): Allow for code in sections other than .text.
(macro): Likewise.
(mips_ip): Likewise.
(md_apply_fix): Do pc-relative relocation madness for MIPS ELF.
Don't perform relocs if we will be outputting them.
(tc_gen_reloc): For ELF, just use fx_addnumber for pc-relative
relocations. Allow BFD_RELOC_16_PCREL_S2 relocs when
embedded-pic.
In gas/testsuite/:
* gas/mips/empic.d: New file.
* gas/mips/empic.s: New file.
* gas/mips/mips16-e.d: New file.
* gas/mips/mips16-e.s: New file.

* gas/mips/mips.exp: Add empic, mips16-e. Add mips16-f as an
expected failure.
In include/elf:
* mips.h: Add R_MIPS_GNU_REL_HI16, R_MIPS_GNU_REL_LO16,
R_MIPS_GNU_REL16_S2, R_MIPS_PC64 and R_MIPS_PC32 relocation
numbers.
* i386gnu-nat.c (gnu_store_registers): Make sure the T bit in the
%eflags isn't modified. This fixes a bug where every call to a
function in the program beyond the first call would fail.
* gdb.base/long_long.exp: Correct test suite failure when printing
a long long value as a double on ARM platforms.
ARM doubles use a hybrid endian format. It is not strictly little or big
endian. It is little endian with the words swapped.
