   2  * These #defines are needed in arm.c and write_object.c to create the
   3  * the mach-o arm relocation r_types ARM_RELOC_HALF and ARM_RELOC_HALF_SECTDIFF.
   4  * The values are internal but can't over lap any of the 4 bit r_type values
   5  * they they are outside that 4 bit range.  But they are picked so we can use
   6  * the low two bits for the r_length encoding.
