<h2>New Targets and Target Specific Improvements</h2>
<ul>
+ <li>The x86 back end has had some noticeable work done to it.
+ <ul>
+ <li>Tuning for K8 core is available via <code>-march=k8</code> and <code>-mcpu=k8</code>
+ <li>Scalar SSE code generation carefully avoids reformatting penalties, hidden dependencies
+ and minimize amount of uops generated on both Intel and AMD CPUs.
+ <li>Conditional jump elimination is now more aggressive on modern CPUs.
+ <li>The Athlon and K8 port have been converted to use the DFA processor pipeline description.
+ <li>Number of other small performance improvements.
+ </ul>
