  84. <p>Each target machine supported by GCC can have its own options&mdash;for

  85. example, to allow you to compile for a particular processor variant or

  86. ABI, or to control optimizations specific to that machine.  By

  87. convention, the names of machine-specific options start with

  88. &lsquo;<samp>-m</samp>&rsquo;.

  89. </p>

  90. <p>Some configurations of the compiler also support additional target-specific

  91. options, usually for compatibility with other compilers on the same

  92. platform.
