...two.  This is reasonable for types such as ‘<3 x float>’.  Maybe we need to add another legalization operation which will mean widening the vectors?  In any case, I estimated that implementing this per-element promotion would require major changes and decided that this is not the way to go. _Packed_ I followed Duncan’s original suggestion which was packing vectors of i1s into general purpose registers. I started by adding several new types to ValueTypes (td and h).  I added ‘4vi1, 8vi1, 16vi1 … 64vi1’.  For x86, I mapped the v8i1 .. v8i64 to general purpose x86 registers. I started playing wit...
