    arm: add a cpu flag for the VFPv2 vector mode · e2710e79
    Janne Grunau authored
    The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu
    implementations do not support it in hardware. Vector mode code will
    depending the OS either be emulated in software or result in an illegal
    instruction on cpus which does not support it. This was not really
    problem in practice since NEON implementations of the same functions are
    preferred. It will however become a problem for checkasm which tests
    every cpu flag separately.
    Since this is a cpu feature newer cpu do not support anymore the
    behaviour of this flag differs from the other flags. It can be only
    activated by runtime cpu feature selection.
