6.9. VFP directives and vector notation

This section applies only to armasm. The inline assemblers in the C and C++ compilers do not accept these directives or vector notation.

You can make assertions about VFP vector lengths and strides in your code, and have them checked by the assembler. See:

If you use VFPASSERT directives, you must specify vector details in all VFP data processing instructions. The vector notation is described below. If you do not use VFPASSERT directives you must not use this vector notation.

In VFP data processing instructions, specify vectors of VFP registers using angle brackets:

You can use this vector notation with names defined using the DN and SN directives (see DN and SN).

You must not use this vector notation in the DN and SN directives themselves.
