-Valid cases of @samp{i@var{x}86} include @samp{i386}, @samp{i486},
-@samp{i586}, and @samp{i686}. All of those configurations produce a
-library that can run on this processor and newer processors. The GCC
-compiler by default generates code that's optimized for the machine it's
-configured for and will use the instructions available on that machine.
-For example if your GCC is configured for @samp{i686}, gcc will optimize
-for @samp{i686} and might issue some @samp{i686} specific instructions.
-To generate code for other models, you have to configure for that model
-and give GCC the appropriate @samp{-march=} and @samp{-mcpu=} compiler
-switches via @var{CFLAGS}.
