| * 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. |
