API changes are:</p>
<ul>
<li>...</li>
<li><tt>ModuleProvider</tt> has been <a
href="http://llvm.org/viewvc/llvm-project?view=rev&revision=94686">removed</a>
and its methods moved to <tt>Module</tt> and <tt>GlobalValue</tt>.
Most clients can remove uses of <tt>ExistingModuleProvider</tt>,
replace <tt>getBitcodeModuleProvider</tt> with
<tt>getLazyBitcodeModule</tt>, and pass their <tt>Module</tt> to
functions that used to accept <tt>ModuleProvider</tt>. Clients who
wrote their own <tt>ModuleProvider</tt>s will need to derive from
<tt>GVMaterializer</tt> instead and use
<tt>Module::setMaterializer</tt> to attach it to a
<tt>Module</tt>.</li>
<li><tt>GhostLinkage</tt> has given up the ghost.
<tt>GlobalValue</tt>s that have not yet been read from their backing
storage have the same linkage they will have after being read in.
Clients must replace calls to
<tt>GlobalValue::hasNotBeenReadFromBitcode</tt> with
<tt>GlobalValue::isMaterializable</tt>.</li>
</ul>
