These originate, I think, from the old e500 ABI; in +any case, they are only defined for 32-bit ABIs, and there is a +significant amount of code in bfd/elf32-ppc.c to handle them +appropriately, none of which is in elf64-ppc.c. However, the +assembler can generate them when building 64-bit code for processors +such as e5500 (which uses PPC_OPCODE_E500MC).
