Rodolphe, My platform (Zynq) has Neon and vfp (see /proc/cpuinfo in the first post). My first post contains the different configurations I tried for building V8. If nothing special is specified (except arm.release or arm.debug), isn't vfp enabled automatically ? Or do I need to specify this explicitly ? Shouldn't soft fp work anyway, regardless of the fact that hard fp is possible ?
