and P_LINK_W.
(P_PEA_FP, P_MOVL_SP_FP): New macros.
(P_MOVL, P_LEAL, P_MOVML): Macros renamed from P_MOV_L, P_LEA_L and
P_MOVM_L.
(altos_skip_prologue, isi_skip_prologue): Use P_* macros, not octal
constants.
(delta68_in_sigtramp): New function.
(delta68_frame_args_address, delta68_frame_saved_pc): Ditto.
(m68k_skip_prologue): Use P_* macros, not hex constants.
(m68k_find_saved_regs): Do not expect a fixed sequence of register save
instructions, but accept them in any order; use P_* macros, not octal
or hex constants; recognize also `fmovemx to (fp + displacement)' and
`moveml to (fp + displacement)'.

(FRAME_SAVED_PC, FRAME_ARGS_ADDRESS): Ditto.
From David Whedon <dwhedon@gordian.com>
* top.c (execute_command): Checks all commands beore executing
to see if the user needs to be warned that the command is
deprecated, warns user if appropriate.
(add_info), (add_info_alias), (add_com) , (add_com_alias): Changed
return values from void to struct cmd_list_element *.
* command.c (lookup_cmd_1): Check aliases before following link
in case user needs to be warned about a deprecated alias.
(deprecate_cmd): new exported function for command deprecation,
sets flags and posibly a replacement string.
(deprecated_cmd_warning): New exported funciton to warn user about
a deprecated command.
(lookup_cmd_composition): New exported function that determines
alias, prefix_command, and cmd based on a string. This is useful
is we want to full name of a command.
* command.h : Added prototypes for deprecate_cmd,
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.
From Philippe De Muyter <phdm@macqel.be>

(i386_extract_return_value): Rewritten. Correctly support all
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.
(insert_breakpoints): Try to insert watchpoints for all the values
on the value chain, even if some of them fail to insert.
* values.c (value_primitive_field): Set the offset in struct value
we return when the field is a packed bitfield.
* remote.c (remote_threads_extra_info): new function.
Implement the extra thread info query for "info threads".

out that these are target-dependent, and useful in non-native

* i386-linux-tdep.c: ... Here, a new file.
* Makefile.in (ALLDEPFILES): Add i386-linux-tdep.c.
(i386-linux-tdep.o): New rule.
(i386-linux-nat.o): We no longer depend on frame.h.
* config/i386/linux.mt (TDEPFILES): Add i386-linux-tdep.o.
* event-loop.c (top-level) [NO_FD_SET]: Deprecate this branch.
Print an error at compile time if we are to use select, but FD_SET
is not available.
(SELECT_MASK, NBBY, FD_SETSIZE, NFDBITS, MASK_SIZE): Define only
if HAVE_POLL is not defined and NO_FD_SET *is* defined.
(create_file_handler) [!HAVE_POLL]: Use FD_SET and FD_CLR.
(delete_file_handler) [!HAVE_POLL]: Use FD_CLR and FD_ISSET.
(gdb_wait_for_event) [!HAVE_POLL]: Copy fd_set sets directly
instead of using memcpy and memset. Use FD_ISSET.

Linux-specific signal trampoline detection, and should be moved to...

* 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.
* 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.

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.

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.
