/* SOM allows any one of the four previous relocations to be reused
with a "R_PREV_FIXUP" relocation entry. Since R_PREV_FIXUP
relocations are always a single byte, using a R_PREV_FIXUP instead
of some multi-byte relocation makes object files smaller.
Note one side effect of using a R_PREV_FIXUP is the relocation that
is being repeated moves to the front of the queue. */
