On AArch64 Linux, a machine register dump is printed as follows:

-- Machine register context ------------------------------------------------
 "x0: 0x0000000000000000 "x1: 0x000000000000000b "x2: 0x0000000000000000
 "x3: 0x5345475600000000 "x4: 0x0000000000000000 "x5: 0x5345475600000000
 "x6: 0x000000000108e600 "x7: 0x000000000000f00f "x1: 0x0000000000000000
 "x1: 0x000000000000000b "x2: 0x0000005501286080 "x2: 0x0000000000003020
 "x2: 0x0000000000000002 "x2: 0x0000000000000001 "x2: 0x0000000000000001
 "x2: 0x0000000000000001 "x2: 0x0000005500b85264 "x2: 0x0000005500b8518c

 "fa: 0x0000000000000000

As you can see above, the register names are indistinguishable. For example, there are 11 registers labeled "x2.

It should be printed as follows:

-- Machine register context ------------------------------------------------
  x0: 0x0000000000000000  x1: 0x000000000000000b  x2: 0x0000000000000000
  x3: 0x5345475600000000  x4: 0x0000000000000000  x5: 0x5345475600000000
  x6: 0x000000000108e600  x7: 0x000000000000f00f x18: 0x0000000000000000

The same goes for ARM Linux.
