## 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.

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