well then that worries me more.
I'm seeing a usage from 5c that is like this:
MOVW $16384, R3
MOVE $1038, R2
MOVW.P R2, 4(R3)
the problem is that it shouldn't be 4(R3), it should be 0(R3). And the
pre-increment only makes it worse. I can't quite figure out what 5c is
doing here.
any ARM guys left out there?
