Add compact_stub.
(emum _ovly_flavour): Delete ovly_compact, ovly_none.

entry point for stubs in non-icache area.

descriptors.
(spu_elf_build_stubs): And don't built them.

reduced data.

make sure we have a GOT section.

broken out of add_from_object.
(Symbol_table::add_from_object): Call define_default_version.
(Symbol_table::define_special_symbol): Add resolve_oldsym
parameter. Change all callers. If the version for a symbol comes
from a version script, resolve it with the symbol with the same
name with no version. Also add the symbol without a version if
appropriate.
(do_define_in_output_data): If resolving with oldsym, don't delete
sym.
(do_define_in_output_segment): Likewise.
(do_define_as_constant): Likewise.

value of disassemble-next-line.
(gdb_disassembly_stub_args): New struct for argument passing
between function do_gdb_disassembly and function
gdb_disassembly_stub.
(gdb_disassembly_stub): New function. Helper for
gdb_disassembly.
(do_gdb_disassembly): New function. Use TRY_CATCH to catch
the exception from the gdb_disassembly because it will be
broken by filter sometime.
(print_frame_info): If disassemble-next-line is set to auto
or on and doesn't have the line debug messages for $pc,
output the next instruction.
If disassemble-next-line is set to on and there is line debug
messages, output assembly codes for next line.
(_initialize_stack): Make the "set disassemble-next-line"
command an auto-boolean command. Change its class to
class_stack. Place it in the top level set list. Extend help
to describe the auto mode.
Use the ops parameter to get to the target beneath, rather than
using the current_target global. Using the current_target global
was an unintended accident.

crashing all the time.
* aix-thread.c (base_target): Delete.
(pd_enable): Do not set base_target.

generating overlays if fixed sections plus reserved stack
and heap space fit into local store.
* stack.c (return_command <retval_exp>): New variables retval_expr
and old_chain. Inline parse_and_eval to initialize retval_expr. Check
RETVAL_EXPR for UNOP_CAST and set RETURN_TYPE to the RETURN_VALUE type
if RETURN_TYPE is NULL.
