Right.  One of my favorite things about VIS is how flexible it is.  You
can do cool things like using fpmerge to double 8-bit data:

        membar  #StoreLoad
        ldda    [%o0]0xF0,%f0
        fpmerge %f0,%f0,%f16
        fpmerge %f1,%f1,%f18
        fpmerge %f2,%f2,%f20
        fpmerge %f3,%f3,%f22
        fpmerge %f4,%f4,%f24
        fpmerge %f5,%f5,%f26
        fpmerge %f6,%f6,%f28
        fpmerge %f7,%f7,%f30
        stda    %f16,[%o1]0xF0
        membar  #StoreLoad

Naturally you'd want to overlap your ldda/stda's and unroll a loop around
this to keep the memory bus flowing at the same time as the FP units.
