Why does the following assembly produce errors on BOOKE?
mtsprg 7, %r3
Looking at the sources, opcode/ppc-opc.c, I see that the mtsprg macro
only takes 2-bit sprg register numbers, which is apparently correct for
the basic ppc architecture, but not for e500. This should probably be
conditional on the architecture choice. I haven't looked at any
architecture or processor manuals to double check.
Meanwhile, "mtsprg7 %r3" will work. Likewise for mfsprg.
