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