armasm implements an extension to the architectural Advanced SIMD assembly syntax, called extended notation. This extension allows you to include datatype information or scalar indexes in register names.
If you use extended notation, you do not have to include the data type or scalar index information in every instruction.
Register names can be any of the following:
QN directives to define names for typed and scalar registers.
