   6 ## FileCheck does not like wrapping arithmetic, so we specify all 3 check variables manually:
   7 ##   ADDEND  := inline/outline addend, unsigned
   8 ##   OUTLINE := outline addend, signed
   9 ##   REBASE  := target of rebase; 0x1000 + ADDEND, unsigned
  10
  11 ## We can use the DYLD_CHAINED_IMPORT import format if 0 <= ADDEND <= 255 bytes.

  21 ## DYLD_CHAINED_IMPORT_ADDEND is used if the addend fits in a 32-bit signed integer.
