Currently this option is -supported in two configurations: (i) with armv8.2-a as the base architecture where all the supported ISA features are enabled and -(ii) with armv8-a as the base architecture where only a subset of ISA features (everything except FP16 vector arithmetic) -are enabled in the build. +supported in two configurations: (i) with armv8.2-a (ii) with armv8-a.
