LLVM API changes are:</p>
<ul>
-
+<li>The biggest and most pervasive change is that llvm::Type's are no longer
+ returned or accepted as 'const' values. Instead, just pass around non-const
+ Type's.</li>
+
<li><code>PHINode::reserveOperandSpace</code> has been removed. Instead, you
must specify how many operands to reserve space for when you create the
PHINode, by passing an extra argument into <code>PHINode::Create</code>.</li>
