Try `maint print {raw-,}registers' and `set debug target 1'. DanielJ's
hunch about swapping the low/high words looks right.
The existing MIPS code does evil stuff related to register raw size. It
current stores 32 bit register values in the lower half of a 64 bit raw
register, rather than the least significant half. But only sometimes
and not consistently :-(
