/* The relocation directory entry types. |

PAIR : The low half that follows relates to the preceding 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. |

|
relocation types, but it appears to be useless for the i860. |

any object files. */ |
