@ -240,6 +240,11 @@ optimization. The LLVM optimizer now notices long sequences of consequtive
stores and merges them into <tt>memcpy</tt>s where profitable.</li>
<li>Alignment detection for vector memory references and for <tt>memcpy</tt> and
<tt>memset</tt> is now more aggressive.</li>
<li>The aggressive dead code elimination (ADCE) optimization has been rewritten to make
it both faster and safer in the presence of code containing infinite loops.
Some of its prior functionality has been factored out into the loop deletion
pass, which <em>is</em> safe for infinite loops.</li>
