Experience shows that people will use every opportunity to shot themselfes into their foot ... Even a soft-fp system may still have the in-kernel emulator, so be able to execute both soft-fp and hard-fp binaries correctly. But it won't be able to support a mix of both nor would the kernel know that an application is just mixing hard and soft fp. Ralf
