AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case.
Define GDB_MULTI_ARCH.
* config/sparc/tm-sparclet.h: Add GDB_MULTI_ARCH configuration.
Do not define GDB_MULTI_ARCH (bfd does not correctly identify target).
* config/sparc/tm-sparclite.h: Ditto.
* config/sparc/tm-sun4sol2.h: Define GDB_MULTI_ARCH.
* sparclet-rom.c (sparclet_regnames): Initialize explicitly, to

used must be the index of the section where 'sym' resides,
not .text.
* procfs.c (many functions): change int cmd; to long cmd;
Solaris /proc API calls this parameter a long, and requires it
for 64-bit hosts (where sizeof(long) != sizeof(int)). UnixWare
calls it an int, but on existing UnixWare hosts, int and long
are the same size. So long it must be. If a future UnixWare
version has problems with this, we'll have to use autoconf.
* proc-api.c (write_with_trace): use long instead of int.
* solib.c (elf_locate_base, info_sharedlibrary_command):
Look at the bfd to determine if it is elf32 or elf64, rather

casting problems when int and pointer are not the same size.
* event-top.c (command_handler): use data as a union.

deprecated_warn_user and lookup_cmd_composition, added flags to
the cmd_list_element structure, changed return values for
add_com_* and add_info_* from void to cmd_list_element.
* maint.c : (maintenance_deprecate): New function to deprecate a
command. This exists only so that the testsuite can deprecate
commands at runtime and check the warning behavior.
(maintenance_undeprecate) : New function, drops deprecated flags.
(maintenance_do_deprecate): Actually does the (un)deprecation.
(initialize_maint_cmds): Added the above new deprecate commands.
* sol-thread.c (ps_pglobal_lookup): Change argument type from
paddr_t to psaddr_t. This mistake appears to date from an
erroneous man page in Solaris 2.5 -- the correct type from the
system headers has always been psaddr_t.
(ps_pdread, ps_pdwrite, ps_ptread, ps_ptwrite): ditto.
(rw_common): ditto.

floating-point types and large integer types on targets that use
the standard i386 GDB register layout and return floating-point
values in the FPU.
* breakpoint.c (insert_breakpoints, remove_breakpoint)
(bpstat_stop_status, can_use_hardware_watchpoint): Don't insert,
remove, or check status of hardware watchpoints for entire structs
and arrays unless the user explicitly asked to watch that struct
or array.

* Makefile.in (ALLDEPFILES): Add i386-linux-tdep.c.
(i386-linux-tdep.o): New rule.

* 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.
* 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.

* 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.

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,

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.

(store_register): Support 32 FP registers.
(go32_create_inferior): Don't crash if handed a NULL pointer
instead of exec file name.

argument to be identical to the corresponding message in
`inftarg.c'. This makes the testsuite happy.
* 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.

* objfiles.h (MINIMAL_SYMBOL_HASH_SIZE): New define.
(struct objfile): New fields `msymbol_hash',
`msymbol_demangled_hash'.
* i386-linux-nat.c: Use elf_gregset_t and elf_fpregset_t instead
of gregset_t and fpregset_t. Those are the only names that are
guaranteed to specify the right types for all supported Linux
systems out there.
Various doc fixes and gratitious local variable renames, all in an
attempt to stress similarities between the code and unify the
terminology used. Use ISO-C all over.
(regmap): Remove trailing comma.
(FPREG_ADDR): Renamed from FPREGSET_T_FPREG_ADDR.
(convert_to_gregset): Make static. Remove GDB_REGS argument. It
is unnecessary and wasn't used anyway. All callers changed.
(convert_to_fpregset, convert_to_xfpregset): Likewise.
(fetch_regs, store_regs): Remove unused variable `regno'.
(fill_fpregs): If REGNO is not -1, only update the specified
register.
(fetch_core_registers): Renamed from
i386_linux_fetch_core_registers. There is no need for a unique
name since the function is static anyway.
(linux_elf_core_fns): Renamed from i386_linux_nat_core_functions
since it is more descriptive.
Fix support for Linux/i386 signal trampolines. The old approach
didn't work for Linux 2.2 and beyond, and didn't work with recent
versions of the GNU C library.

(i386_linux_in_sigtramp): New function.
(i386_linux_sigcontext_addr): New function. Recognize the names
of the signal tranmpolines used by recent versions of the GNU C
library, and add support for RT signals.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET): New
defines. Moved here from config/i386/tm-linux.h.
(i386_linux_sigtramp_saved_pc, i386_linux_sigtramp_saved_sp):

(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET):
Moved to i386-tdep.c.
