| 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. | |
