/* The relocation directory entry types.
     PAIR   : The low half that follows relates to the preceeding HIGH[ADJ].
     HIGH   : The high half of a 32-bit constant.
     LOWn   : The low half, insn bits 15..(n-1), 2^n-byte aligned. 
     SPLITn : The low half, insn bits 20..16 and 10..(n-1), 2^n-byte aligned. 
     HIGHADJ: Similar to HIGH, but with adjustment.
     BRADDR : 26-bit branch displacement.

   Note: The Intel assembler manual lists LOW4 as one of the
   relocation types, but it appears to be useless for the i860.
   We will recognize it anyway, just in case it actually appears in
   any object files.  */
