+
+<pre>
+ <b>virtual bool</b> runOnMachineFunction(MachineFunction &MF) = 0;

+
+<tt>runOnMachineFunction</tt> can be considered the main entry point
+of a <tt>MachineFunctionPass</tt>; that is, you should override this
+method to do the work of your <tt>MachineFunctionPass</tt>. <p>
+
+The <tt>runOnMachineFunction</tt> method is called on every
+<tt>MachineFunction</tt> in a <tt>Module</tt>, so that the
+<tt>MachineFunctionPass</tt> may perform optimizations on the
+machine-dependent representation of the function. If you want to get
+at the LLVM <tt>Function</tt> for the <tt>MachineFunction</tt> you're
+working on, use <tt>MachineFunction</tt>'s <tt>getFunction()</tt>
+accessor method -- but remember, you may not modify the LLVM
+<tt>Function</tt> or its contents from a
+<tt>MachineFunctionPass</tt>. <p>
