Is it OK to commit?
Nearly. ;-)
Please consider the following remarks and apply the resulting patch
after sending it to gcc-patches (without waiting for further approval).
Thanks.
I've commited the following.

+<h2><a name="intro">Introduction</a></h2>
+
+<p>The goal of this project is to add a new extension for improving the code
+size optimization of GCC with code factoring methods (code motion and merging
+algorithms). The implementation currently resides on the branch.</p>
+
+<h2><a name="documentation">Documentation</a></h2>
+
+<p>The project includes the following two code factoring algorithms:</p>
+<ul>
+<li>Local code factoring: This is a code motion technique. It tries to merge two
+identical instructions.</li>
+<li>Sequence abstraction: This algorithm merges identical code sequences. It is
+nearly the opposite of function inlining.</li>
+</ul>
+
+<p>Both algorithms have an opportunity of working on two different levels
+(Tree, RTL). Both have their own advatages, disadvatages.
+This project holds both types for future investigations. </p>
