As of version 4.3.0, GCC offers the {{ic|1=-march=native}} switch that enables CPU auto-detection and automatically selects optimizations supported by the local machine at GCC runtime. To use it, just modify the default settings by changing the {{ic|CFLAGS}} and {{ic|CXXFLAGS}} lines as follows: | As of version 4.3.0, GCC offers the {{ic|1=-march=native}} switch that enables CPU auto-detection and automatically selects optimizations supported by the local machine at GCC runtime.
