 **Notes and Observations**:
 
-1. minimum/maximum instructions are needed for vector reductions, where the SVP64 tree reduction needs a single instruction to work properly.
-2. if you implement any of the FP min/max modes, the rest are not much more hardware.
-3. FP min/max are rather complex to implement in software, the most commonly used FP max function `fmax` from glibc compiled for SFFS is 32 (!) instructions.
