   struct fix *fixP is the fixup md_apply_fix is operating on. valueT *valP is
   the value to store into the object files, or at least is the generic code's
   best guess. Specifically, *valP is the value of the fixup symbol, perhaps
   modified by MD_APPLY_SYM_VALUE, plus fixP->fx_offset (symbol addend), less
   MD_PCREL_FROM_SECTION for pc-relative fixups. segT seg is the section the
   fix is in. fixup_segment performs a generic overflow check on *valP after
   md_apply_fix returns. If the overflow check is relevant for the target
   machine, then md_apply_fix should modify *valP, typically to the value
   stored in the object file. */
