...ant the simulation to be as good as possible*. *An iteration Approach* My current approach of getting the best simulation is a strategy-based iteration algorithm. For example, simd<4>::add can be implemented based on simd<8>::add in the following manner. ===strategy_add_doubling=== 1. hiMask = simd<8>::himask() //this is a constant with high 4 bits of each 8-bits field are 1111 and low 4 bits of each 8-bits field are 0000. 2. loMask = simd<8>::lowmask() //this is a constant with high 4 bits of each 8-bits field are 0000 and low 4 bits of each 8-bits field are 1111. 3. c = s...

Hi Bruce, Thanks for response. I also think it is not good way. Do you have the other ways to legalize it?
