...alizing the formation of <8 x float> vectors. This may work, but will cause an unnecessary compile-time increase. 2. Add some kind of API to TTI that allows the default logic (# == vector-size/type-size) to be overridden. This could be something specific to the problem at hand, such as: bool areFloatsStoredAsDoublesInVectors(), or something more general. Maybe something like: unsigned getSizeAsVectorElement(Type *T) which would return the number of bytes that the specified type actually takes up when used as a vector element. I'm certainly open to suggestions. I don't know if this situation applies to other ta...

Add some kind of API to TTI that allows the default logic (# == vector-size/type-size) to be overridden.
