(get_extended_arelt_filename): Add origin parameter. (_bfd_generic_read_ar_hdr_mag): Deal with extended name combined with a file offset. (append_relative_path): New function. (_bfd_get_elt_at_filepos): Deal with external members and nested archives. (bfd_generic_openr_next_archived_file): Thin archives. (bfd_generic_archive_p): Recognize new magic string. (adjust_relative_path): New function. (_bfd_construct_extended_name_table): Construct extended names for thin archive members. (_bfd_write_archive_contents): Emit new magic string, skip copying files for thin archives. * bfd/bfd-in.h (bfd_is_thin_archive): New macro. * bfd/bfd.c (struct bfd): New fields for thin archives. * bfd/libbfd-in.h (struct areltdata): New field for thin archives. * bfd/opncls.c (bfd_close): Delete BFDs for nested archives. * binutils/ar.c (make_thin_archive): New global flag. (map_over_members): Deal with full pathnames in thin archives. (usage, main): Add 'T' option for building thin archives. (replace_members): Pass thin archive flag to ar_emul_append. * binutils/arsup.c (ar_open): Initialize new flag. * binutils/binemul.c (ar_emul_append): Add new parameter for flattening nested archives. (do_ar_emul_default_append): New function. (ar_emul_default_append): Factored out recursive code. * binutils/binemul.h (ar_emul_default_append): Add new parameter. (struct bin_emulation_xfer_struct): New parameter for ar_append. * binutils/dlltool.c (gen_lib_file): Initialize thin archive flag. * binutils/emul_aix.c (ar_emul_aix_internal): Add new flatten parameter, currently unimplemented. All callers changed. * binutils/objcopy.c (copy_archive): Preserve thin archive flag. * binutils/doc/binutils.texi: Update ar documentation. * binutils/testsuite/binutils-all/ar.exp: Add thin archive tests. * include/aout/ar.h (ARMAGT): New magic string for thin archives. --- bfd/bfd.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'bfd/bfd.c') diff --git a/bfd/bfd.c b/bfd/bfd.c index ce7b391..7e6e872 100644 --- a/bfd/bfd.c +++ b/bfd/bfd.c @@ -150,6 +150,13 @@ CODE_FRAGMENT . origin, with origin set to 0 for non archive files. *} . ufile_ptr origin; . +. {* The origin in the archive of the proxy entry.
