Oh perfect -- I did do an initial grep to see if this was done but couldn't immediately find it. The Power ISA does guarantee that unaligned word/doubleword reads are handled transparently by the hardware so enabling this seems like a reasonable approach on PPC as well. I'll submit a v2 that does this. > ~Andrew Thanks, Shawn
