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.
