Have you tested this support with a userspace containing floating point instructions? I wonder if CONFIG_MATH_EMULATION is going to need work at all, and if the boards with an actual FPU (440EP, 440EPx, 460EX, etc) would have issues. josh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
