@bryanpkc Good point. The same is said also in Arm ARM, section A2.1.1.
There is already a description at https://github.com/llvm/llvm-project/blob/ba4d36951f1deaf24dce526900a2d6dbdefa377b/llvm/lib/Target/AArch64/AArch64.td#L1513
Shouldn't it include both `FeatureJS` and `FeatureComplxNum` ?
Once you have that, I would expect `+nosimd` to disable FEAT_FCMA and `+nofp` to disable both `FEAT_FCMA` and `FEAT_JSCVT`.
