Note that the NEON unit doesn't implement the deeper parts of IEEE754 floating point like NaN and exceptions. These are needed for general purpose applications but not, say, radial fills in graphics. Turning on -ffast-math allows the compiler to send floating point operations via NEON instead of VFP. -- Michael _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
