code repeated three times in bfd_section_from_shdr in elfcode.h.
* libelf.h (_bfd_elf_make_section_from_shdr): Declare.
* elfcode.h (bfd_section_from_shdr): Use new function
_bfd_elf_make_section_from_shdr to create BFD sections. If a
reloc section does not use the main symbol table, or it is part of
the process image, treat it as a normal section, not relocs.
* elf32-mips.c (mips_elf_section_from_shdr): Use new function
_bfd_elf_make_section_from_shdr.
* ld.h (ld_config_type): Add field dynamic_link.
* ldmain.c (main): Initialize config.dynamic_link to false. Warn
on attempts to use -r with -relax, -call_shared or -s.
* lexsup.c (longopts): Separate OPTION_CALL_SHARED from
OPTION_NON_SHARED. Add OPTION_IGNORE. Adjust macro values
accordingly. Add "dy" and "non_shared" options. Change "Qy" to
OPTION_IGNORE for now. Handle OPTION_CALL_SHARED and
OPTION_NON_SHARED by setting dynamic_link field accordingly.
Handle OPTION_IGNORE by ignoring it. Clear dynamic_link field for
-r and -Ur.
* ldfile.c (ldfile_open_file): If config.dynamic_link is true, try
opening a file with a .so extension first.
* emultempl/elf32.em: New file.
* emulparams/elf32_sparc.sh (TEXT_START_ADDR): Change to 0x10000.
(NONPAGED_TEXT_START_ADDR): Likewise.
(TEMPLATE_NAME): Define as elf32.
(DATA_PLT): Define.
* emulparams/elf_i386.sh (TEMPLATE_NAME): Define as elf32.
* scripttempl/elf.sc: Add placement for new dynamic sections.
Don't use CREATE_OBJECT_SYMBOLS. Define _etext, _edata and _end
outside of any section. Don't use ALIGN(8); just let one section
VMA follow another. Put .dynbss in .bss. Don't mention debugging
sections; they'll be handled correctly anyhow.
* Makefile.in (eelf_i386.c): Depend upon elf32.em, not generic.em.
Eric Youngdale <ericy@cais.com>.

linking: elf_backend_create_dynamic_sections,

dynstr, bucketcount.

(elf_swap_reloc_in): Define as macro using NAME. Make externally
visible.

section names.

(map_program_segments): Completely rewrite.
(assign_file_positions_except_relocs): Completely rewrite.
(assign_file_positions_for_relocs): Don't set a file position for
sections which already have one. Don't bother to align the file
position here.
(section_from_elf_index): Handle SHT_HASH and SHT_DYNAMIC
section types.
(elf_section_from_bfd_section): Likewise.
(elf_slurp_symbol_table): If section_from_elf_index fails, just
use bfd_abs_section rather than returning an error.
(elf_sizeof_headers): Make useful.
(elf_link_record_dynamic_symbol): New static function.
(elf_link_add_object_symbols): Handle dynamic objects.
(elf_link_create_dynamic_sections): New static function.

(NAME(bfd_elf,size_dynamic_sections)): New function.
(struct elf_final_link_info): Add dynsym_sec and hash_sec fields.
(elf_bfd_final_link): Handle dynamic linking. Create a section
symbol for all ELF sections, not all BFD sections. Store section
symbol index in target_index field, not index field. Traverse
over global symbols even if stripping.
(elf_link_output_extsym): Output dynamic symbols. Mark symbols
defined by dynamic objects as undefined.
(elf_link_input_bfd): Ignore dynamic objects. Use target_index
field for section relocs, and make sure it is set.
(elf_reloc_link_order): Use target_index field for section relocs,
and make sure it is set.
* elf.c (elf_link_hash_newfunc): Initialize dynindx, dynstr_index,
weakdef and elf_link_hash_flags fields.

(som_write_armap): Add elength, map, orl_count and int arguments.
(som_write_armap): Use %ld and cast to long for getuid result.
* xcoffread.c (read_xcoff_symtab): For C_FILE symbols, only use
the auxent if the symbol's name is ".file". From David Edelsohn
<c1dje@watson.ibm.com>.
fputs_unfiltered and exit directly, rather than fatal. The latter
calls vfprintf_unfiltered!
* gdbtypes.h, gdbtypes.c (can_dereference): New function.
* value.h, printcmd.c (print_value_flags): Move from here...
* annotate.c: ...to here, and make it use can_dereference.
* gdb.t00/teststrategy.exp: Reorder so that AIX gdb can print the
version also, match on casted version strings, and match on
gdb startup case where the line numbers might be messed up.
