Remember that it's not just a matter of configuring math emulation into the kernel. The function call ABI is different for soft vs. hard float, so library calls will go kerflooey if you mix the two. If you stick to all hard float user space, you can use kernel math emulation. -- Joe Green MontaVista Software, Inc. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
