Hi! I've been wondering whats the better choice of settings in the make.conf is for the EfikaMX Smartbook Currently i set it like Funtoo's ARM stage3 default, or should i be setting -mfpu=neon instead? CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard" CXXFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard" |

Hi, "better" is a relative term and you may want to simply test what works best for your application. If you plan to use "-mfpu=neon" and expect your code to be auto-vectorized by GCC, you will need to add '-funsafe-math-optimizations' which may cause a loss of precision.
