high-level accessors, such as <tt>getCalledValue</tt> and <tt>setUnwindDest</tt>.

</li>
|

<li>
|

You can no longer pass use_iterators directly to cast<> (and similar), because
|
||||
these routines tend to perform costly dereference operations more than once. You
|

have to dereference the iterators yourself and pass them in.

<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).

SetCurrentDebugLocation takes a DebugLoc now instead of a MDNode.

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

deal with funky triples.
