<li>The X86 backend now generates substantially better code for 64-bit integer
and floating point operations.</li>
<li>The -inline pass no longer inlines mutually recursive functions until it
hits the inlining threshold.</li>
<li>The -inline pass no longer misses obvious inlining opportunities just
because the callee eventually calls into an external function.</li>
<li>The -simplifycfg pass can now "if convert" simple statements into the new
<tt>select</tt> instruction.</li>
<li>The -loopsimplify pass can now break <a
href="http://llvm.cs.uiuc.edu/PR35">natural loops with multiple backedges</a>
into multiple nested loops. This enables a variety of subsequent
optimizations.</li>
<li>The -adce pass can now eliminate calls to functions that do not not write to
memory.</li>
<li>The link-time optimizer now runs the -prune-eh pass (to remove unused
exception handlers.</li>
