/*
* 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.
