This applies only to
armasm. The inline
assemblers in the C and C++ compilers do not accept these directives
or vector notation.
The use of VFP vector mode is deprecated, and vector notation is not supported in UAL. To use vector notation, you must use the pre-UAL VFP mnemonics. See Pre-UAL VFP mnemonics for details. You can mix pre-UAL VFP mnemonics and UAL VFP mnemonics.
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 written using
pre-UAL mnemonics. The vector notation is described in Vector notation. If you do not
VFPASSERT directives you must not use this notation.
