+       relocs against the .text section as required.
+       * ecofflink.c (bfd_ecoff_debug_accumulate): When relaxing, adjust
+       PDR addresses as required.
+
        * ecoff.c (ecoff_emit_aggregate): Take fdr argument.  Map fdr
        index through rfd map if it exists.  Check for a couple of cases
        which gdb handles specially.  Change all callers.
