感谢~~
Q:
R8 = 0x11223344
R9 = 0xFADEABAD
R10 = 0x55667788
What is final value of R2 in hexadecimal, using all eight
digits (that is write 0x00000000 and not 0x0), after the
execution of each sequence of instructions, for both
little- and big-endian machines? If any access in the
sequence is misaligned, write'misaligned' instead of an answer.
- Little-Endian - Big-Endian
