Hi Ana,
It seems that most of the -mattr features only obtain on/off without assigning a value.
For -mfpu=vfp4,  each fpu configuration will be declared as a feature (e.g. FeatureVFP4) and the configurations are limited,
but the threshold value could be any number. 
Did you mean declare as a target feature in `RISCV.td` or I misunderstanding something?
