-  You can no longer pass use_iterators directly to cast<> (and similar), because

-<li>
-  llvm.memcpy.*, llvm.memset.*, llvm.memmove.* (and possibly other?) intrinsics
-  take an extra parameter now (i1 isVolatile), totaling 5 parameters.
-  If you were creating these intrinsic calls and prototypes yourself (as opposed
-  to using Intrinsic::getDeclaration), you can use UpgradeIntrinsicFunction/UpgradeIntrinsicCall
-  to be portable accross releases.
-  Note that you cannot use Intrinsic::getDeclaration() in a backwards compatible
-  way (needs 2/3 types now, in 2.7 it needed just 1).

-<li>
-  The constructor for the Triple class no longer tries to understand odd triple
-  specifications.  Frontends should ensure that they only pass valid triples to
-  LLVM.  The Triple::normalize utility method has been added to help front-ends
