Hi, This patch documents the following options for Arm Cortex-M55 CPU under -mcpu= list. +nomve.fp (disables MVE single precision floating point instructions) +nomve (disables MVE integer and single precision floating point instructions) +nodsp (disables dsp, MVE integer and single precision floating point instructions) +nofp (disables floating point instructions) Committed as obvious to master.
