3.18 Machine-Dependent Options

Each target machine supported by GCC can have its own options—for example, to allow you to compile for a particular processor variant or ABI, or to control optimizations specific to that machine. By convention, the names of machine-specific options start with ‘-m’.

Some configurations of the compiler also support additional target-specific options, usually for compatibility with other compilers on the same platform.
