38 * The rr_lo_hi macro swaps a pair of registers depending on
39 * current endianness. It is used in conjunction with ldrd and strd
40 * instructions that load/store a 64-bit value from/to memory to/from
41 * a pair of registers which are used with the mrrc and mcrr instructions.
42 * If used with the ldrd/strd instructions, the a1 parameter is the first
43 * source/destination register and the a2 parameter is the second
44 * source/destination register. Note that the ldrd/strd instructions
45 * already swap the bytes within the words correctly according to the
46 * endianness setting, but the order of the registers need to be effectively
47 * swapped when used with the mrrc/mcrr instructions.
