objects were seen, even when linking PIC code.
* libelf.h (ELF_LINK_HASH_NEEDS_PLT): Define.
(struct elf_link_hash_table): Add field dynamic_sections_created.
* elfcode.h (elf_link_record_dynamic_symbol): Create dynstr if it
doesn't already exist.
(elf_link_add_object_symbols): Create dynamic sections based on
dynamic_sections_created field, not dynobj field. Don't bother to
set dynobj.
(elf_link_create_dynamic_sections): If dynamic sections were
already created, don't do anything. If dynobj is already set, use
it; otherwise, set it to the bfd argument. Don't initialize
dynsymcount. Only create dynstr if it does not exist. Set
dynamic_sections_created to true.
(NAME(bfd_elf,size_dynamic_sections)): Skip most of this function
if no dynamic objects were seen.
(elf_adjust_dynamic_symbol): If a symbol has the
ELF_LINK_HASH_NEEDS_PLT flag set, let the backend adjust it.
(elf_bfd_final_link): Change most decisions based on dynobj to
check dynamic_sections_created instead.
(elf_link_output_extsym): Only handle dynamic symbols if a dynamic
object was seen.
* elf.c (_bfd_elf_link_hash_table_init): Initialize new field
dynamic_sections_created. Set dynsymcount to 1, not 0.
* elf32-i386.c (elf_i386_create_dynamic_sections): Call
elf_i386_create_got_section rather than creating the .got and
.got.plt sections.
(elf_i386_create_got_section): New static function.
(elf_i386_check_relocs): Just call elf_i386_create_got_section if
a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
Only create the .rel.got section, and only make space for a reloc,
for a global symbol or when generating a shared object. For a
R_386_PLT32 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
(elf_i386_adjust_dynamic_symbol): Rework initial assertion to
permit ELF_LINK_HASH_NEEDS_PLT non dynamic symbols. Create a
procedure linkage table entry for such symbols. But, if no
dynamic objects were seen, never create a PLT entry.
(elf_i386_size_dynamic_sections): If no dynamic objects were seen,
skip most of this function, and force the size of the .rel.got
section to zero.
(elf_i386_relocate_section): For a R_386_GOT32 reloc against a global
symbol when no dynamic object was seen, initialize the contents of
the .got section. For a R_386_GOT32 against a local symbol, only
create a R_386_RELATIVE reloc when generating a shared object.
Treat a R_386_PLT32 reloc against a symbol for which we did not
create a PLT entry as a R_386_PC32 reloc.
(elf_i386_finish_dynamic_sections): Only fiddle with the dynamic
entries and the PLT if we saw a dynamic object.
* elf32-sparc.c (elf_sparc_howto_table): Fix R_SPARC_PC22 by
setting rightshift to 10. Fix R_SPARC_WPLT20 by setting
rightshift to 2, size to 2, bitsize to 30, and dst_mask to
0x3fffffff.
(elf32_sparc_create_dynamic_sections): Don't set the size of the
.plt section. Call elf32_sparc_create_got_section rather than
creating the .got section.
(elf32_sparc_check_relocs): Call elf32_sparc_create_got_section if
a GOT table is needed, not bfd_elf32_link_create_dynamic_sections.
Only create the .rela.got section, and only make space for a
reloc, for a global symbol or when generating a shared object.
Set the alignment of the .rela.got section to 2. For a
R_SPARC_WPLT30 reloc, just set the ELF_LINK_HASH_NEEDS_PLT flag.
(elf32_sparc_adjust_dynamic_symbol): Rework initial assertion to
permit ELF_LINK_HASH_NEDS_PLT non dynamic symbols. Create a
procedure linkage table for such symbols. But, if no dynamic
objects were seen, never create a PLT entry. Initialize the size
of the .plt section.
(elf32_sparc_size_dynamic_sections): If no dynamic objects were
seen, skip most of this function, and force the size of the
.rela.got section to zero. Strip empty reloc sections, and strip
an empty .plt section.
(elf32_sparc_relocate_section): For a GOT reloc against a global
symbol when no dynamic object was seen, initialize the contents of
the .got section. For a GOT reloc against a local symbol, only
create a R_SPARC_RELATIVE reloc when generating a shared object.
Treat a R_SPARC_WPLT30 reloc against a symbol for which we did not
create a PLT entry as a R_SPARC_WDISP30 reloc.
(elf32_sparc_finish_dynamic_sections): Only fiddle with the
dynamic entries and the PLT if we saw a dynamic object.
* config/mt-netware: New file.
* config/mt-i386-netware: Removed, separate configs for different
netware architectures are no longer needed now that we have
--with-headers.
target_wait_hook to allow GUI to handle blocking for inferior. Call
call_command_hook in execute_command to provide means for wrapping
commands with GUI state change updates.
* gdbtk.c (gdb_cmd): Force GUI into idle mode when errors occur.
* (gdb_stop): New tcl command to stop the target process.
* (x_event, gdbtk_wait): Allow GUI to interrupt gdb out of target
waits.
* (gdbtk_call_command): Wrapper around command processing to
alert GUI of target state changes.
* (gdbtk_init): Get the fd of X server for doing async

to just set or clear breakpoints when in the margin tag.
* Change shape of register window to be more vertical to better
reflect it's contents.
* Add stop button.
* Cleanup some code around command window bindings.
* infrun.c (wait_for_inferior): Make sure
through_sigtramp_breakpoint is non-null before deleting.
systems, only use it for "exit 1", and make it set a non-zero exit status;
reset it before "exit 0". Also, check exit status of config.sub, and error out
if it failed.
in a section not owned by any BFD.
(elf_section_from_bfd_section): Separate out loop which calls
backend routine. Check bfd_section and call the backend routine
even for a section not owned by any BFD.

* remote-vx.c (vx_add_symbols): Call it.
* coffread.c (coff_symtab_read): Handle common symbols the same
way that partial-stab.h does.
storage class slightly more verbose. It's not clear how many
characters I can justify using up, but before this change they
both were abbreviated "sc" which is (IMHO) clearly unacceptable.
(define_some_regs): Add new special register names defined on the
29040.
(parse_operand): Add argument opt. If non-zero, don't warn about
a missing operand.
(machine_ip): If handling argument type 'I', pass opt as non-zero
to parse_operand. Handle new optional operand type 'I'.
(md_undefined_symbol): Handle special register names (srNN).
loader that reads files using BFD and converts it on the fly.
* monitor.c (set_loadtype_command): Fixed so it doesn't core dump.

accordingly. Default to gr_load_image().

srecord format by downloading to the monitor.
* w89k-rom.c, op50n-rom.c: set supported load types.
and the start address was not set using --set-start, default the
start address to zero. This hack is because the `binary' output
file format uses the start address to set the virtual address of
the first byte in the file.
* binutils.texi, objcopy.1: Add some notes on generating S-records
and binary files.
(adjust_start, set_start_set, set_start): New static variables.

field if section is removed. Handle --adjust-vma and
--adjust-section-vma.
(copy_section): Correct type of last argument to PTR.
(mark_symbols_used_in_relocations): Likewise.
(strip_main): Clear used field when handling -R.
(copy_main): Handle new options.
* binutils.texi (objcopy): Document new options.

srecord format by downloading to the monitor.
* w89k-rom.c, op50n-rom.c: set supported load types.
rather than messing with Elf_Sym_Extra. Store the symbol index in
the udata.i field.
(swap_out_syms): Use outbound_syms as a pointer rather than as an
array. Don't worry about elf_sym_num.
(elf_symbol_from_bfd_symbol): Use udata.i rather than just udata.

udata.i rather than elf_sym_extra array.
(elf32_hppa_backend_symbol_table_processing): Don't set
symextn_hdr->size; just use sh_size.
