GCC 4.2 introduces a new -march option, -march=native, which automatically detects the features your CPU supports and sets the options appropriately. If you have an Intel or AMD CPU and are using >=sys-devel/gcc-4.2.0, using -march=native is recommended. Do NOT use -march=native if you use distcc on nodes with different architectures as this may produce unusable code.
有多少人不是>=gcc4.2.2的? |
