<h2>General Optimizer Improvements (and Changes)</h2>
+ <li>A new general optimization level, <code>-Og</code>, has been
+ introduced. It addresses the need for fast compilation and a
+ superior debugging experience while providing a reasonable level
+ of runtime performance. Overall experience for development should
+ be better than the default optimization level <code>-O0</code>.
<li>A new option <code>-ftree-partial-pre</code> was added to control
the partial redundancy elimination (PRE) optimization.
This option is enabled by default at the <code>-O3</code> optimization
