+ * opncls.c (find_separate_debug_file): Add include_dirs
+ parameter. Only include the directory part of the bfd's filename
+ in search paths if include_dirs is true. Add a couple of extra
+ locations for looking for debug files.
+ ( bfd_follow_gnu_debuglink): Update invocation of
+ find_separate_debug_file.
+ (bfd_follow_gnu_debugaltlink): Likewise.
+ (get_build_id): New function: Finds the build-id of the given bfd.
+ (get_build_id_name): New function: Computes the name of the
+ separate debug info file for a bfd, based upon its build-id.
+ (check_build_id_file): New function: Checks to see if a separate
+ debug info file exists at the given location, and that its
+ build-id matches that of the original bfd.
+ (bfd_follow_build_id_debuglink): New function: Finds a separate
+ debug info file for a given bfd by using the build-id method.
+ * dwarf2.c (_bfd_dwarf2_slurp_debug_info): Try using the build-id
+ method of locating a separate debug info file before using the
+ debuglink method.
+ * bfd-in2.h: Regenerate.
