<ul>
<li>The type legalization logic has been completely rewritten, and is now
more powerful (it supports arbitrary precision integer types for example)
and hopefully more correct.
The type legalizer converts operations on types that are not natively
supported by the target machine into equivalent code sequences that only use
natively supported types.
The old type legalizer is still available and will be used if
<tt>-disable-legalize-types</tt> is passed to <tt>llc</tt>.
