    It still needs to be determined if the raspi3 actually has 32 64bit fp regs or only 16.

    A raspberrypi 3 identifies its CPU as follows:

    processor : 0
    model name : ARMv7 Processor rev 4 (v7l)
    BogoMIPS : 38.40
    Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32
    CPU implementer : 0x41
    CPU architecture: 7
    CPU variant : 0x0
    CPU part : 0xd03
    CPU revision : 4
