+<tt>runOnMachineFunction</tt> can be considered the main entry point

+
+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
