This means that it is possible to use one of the three built-in indexing registers (`a0`, `a1` and `a2` aka `lcnt`) to address a register, e.g. `someArray[lcnt]`. Adding an offset is also supported, e.g. `someArray[lcnt+2]`. This is useful in FOR loops. +Normal floating-point vector registers may also be negated by prepending a minus sign before it, e.g. `-r2` or `-someArray[lcnt+2]`. + ## Supported Directives ### .proc
