Hi When I tried to build 444.namd with options "-O2 -m64 -mvsx -mcpu=power7", I can see vsx instructions are actually used, there are many xs- started instructions, but none of them use high registers [vsr32 -vsr63], does anybody know the reason?
One example is function calc_pair_energy_fullelect in file ComputeNonbondedUtil.o, there are many vsr register spilling but high vsr registers are never used. thanks Carrot
