* coff-alpha.c (alpha_relocate_section): During final link, allow
output .lita section to be bigger than 64k by adjusting gp value
on a per-input section basis.
* libecoff.h (struct ecoff_tdata): Add issued_multiple_gp_warning
field.
(struct ecoff_section_tdata): Add gp field.

Handle Alpha ECOFF changes in OSF/1 3.2.
* libecoff.h (struct ecoff_backend_data): Add get_elt_at_filepos
field.
* coff-alpha.c: Include "aout/ar.h".
(alpha_ecoff_get_relocated_section_contents): Don't require an
ALPHA_R_IGNORE reloc after an ALPHA_R_GPDISP reloc, since OSF/1
3.2 doesn't generate one.
(alpha_relocate_section): Likewise.
(alpha_ecoff_slurp_armap): Define.
(alpha_ecoff_slurp_extended_name_table): Define.
(alpha_ecoff_construct_extended_name_table): Define.

(alpha_ecoff_openr_next_archived_file): New static function.
(alpha_ecoff_get_elt_at_index): New static function.
(alpha_ecoff_backend_data): Initialize get_elt_at_filepos field.
(ecoffalpha_little_vec): Change BFD_JUMP_TABLE_ARCHIVE from
_bfd_ecoff to alpha_ecoff.
* ecoff.c (ecoff_link_add_archive_symbols): Use get_elt_at_filepos
field from backend structure, rather than always calling
_bfd_get_elt_at_filepos.
* coff-mips.c (mips_ecoff_backend_data): Initialize
get_elt_at_filepos field.
* archive.c (_bfd_generic_read_ar_hdr_mag): New function, copied
from _bfd_generic_read_ar_hdr with minor changes.
(_bfd_generic_read_ar_hdr): Use _bfd_generic_read_ar_hdr_mag.
* libbfd-in.h (_bfd_generic_read_ar_hdr_mag): Declare.
* libbfd.h: Rebuild.
* bfd-in.h (BFD_IN_MEMORY): Define.
* libbfd-in.h (struct bfd_in_memory): Define.
* libbfd.c (bfd_read): Handle BFD_IN_MEMORY flag.
(bfd_get_file_window): Don't try to map a BFD_IN_MEMORY file.
(bfd_write, bfd_stat): Abort if BFD_IN_MEMORY is set.
(bfd_tell, bfd_flush, bfd_seek): Handle BFD_IN_MEMORY flag.
* bfd.c (struct _bfd): Change iostream field from char * to PTR.
(bfd_get_size): Handle BFD_IN_MEMORY flag.
* cache.c (bfd_cache_close): Ignore BFD_IN_MEMORY files.
(bfd_open_file): Cast to PTR, not char *, when setting iostream.
(bfd_cache_lookup_worker): Abort if BFD_IN_MEMORY is set.
* opncls.c (bfd_fdopenr): Cast to PTR, not char *, when setting
iostream.
(bfd_openstreamr): Likewise.
* aoutx.h (NAME(aout,some_aout_object_p)): Only fstat iostream if
BFD_IN_MEMORY is not set.
* riscix.c (riscix_some_aout_object_p): Likewise.
* bfd-in2.h, libbfd.h: Rebuild.
* targets.c (bfd_target): Add _bfd_get_elt_at_index field.
(BFD_JUMP_TABLE_ARCHIVE): Add _get_elt_at_index.
(bfd_get_elt_at_index): Define.
* archive.c (_bfd_generic_get_elt_at_index): Rename from
bfd_get_elt_at_index. Change index parameter from int to
symindex.
* libbfd-in.h (_bfd_generic_get_elt_at_index): Declare.
(_bfd_noarchive_get_elt_at_index): Define.
(_bfd_archive_bsd_get_elt_at_index): Define.
