In pre-UAL VFP data processing instructions, specify vectors of VFP registers using angle brackets:
sis a single-precision scalar registernnsis a single-precision vector whose length and stride are given by the current vector length and stride, as defined byn<>VFPASSERT VECTOR. The vector starts at registernsis a single-precision vector of length L, stride 1. The vector starts at registern<L>nsis a single-precision vector of lengthn<L:S>LSndis a double-precision scalar registernndis a double-precision vector whose length and stride are given by the current vector length and stride, as defined byn<>VFPASSERT VECTOR. The vector starts at registerndis a double-precision vector of length L, stride 1. The vector starts at registern<L>ndis a double-precision vector of lengthn<L:S>LSn
You can use this vector notation with names defined using
the DN and SN directives.
You must not use this vector notation in the DN and SN directives
themselves.
