<li>Just about everything has been converted to use <tt>raw_ostream</tt> instead of

<li><tt>llvm/ADT/iterator.h</tt> has been removed, just use <tt>&lt;iterator&gt;</tt>
instead.</li>
<li>The <tt>Streams.h</tt> file and <tt>DOUT</tt> got removed, use <tt>DEBUG(errs() &lt;&lt; ...);</tt>
instead.</li>
<li>The <tt>TargetAsmInfo</tt> interface was renamed to <tt>MCAsmInfo</tt>.</li>
<li><tt>ModuleProvider</tt> has been <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. <li>The <tt>add</tt>, <tt>sub</tt>, and <tt>mul</tt> instructions no longer
<tt>GlobalValue</tt>s that have not yet been read from their backing support floating-point operands. The <tt>fadd</tt>, <tt>fsub</tt>, and
storage have the same linkage they will have after being read in. <tt>fmul</tt> instructions should be used for this purpose instead.</li>
Clients must replace calls to
<tt>GlobalValue::hasNotBeenReadFromBitcode</tt> with
<tt>GlobalValue::isMaterializable</tt>.</li>
<li>The <tt>isInteger</tt>, <tt>isIntOrIntVector</tt>, <tt>isFloatingPoint</tt>,
<tt>isFPOrFPVector</tt> and <tt>isFPOrFPVector</tt> methods have been renamed
<tt>isIntegerTy</tt>, <tt>isIntOrIntVectorTy</tt>, <tt>isFloatingPointTy</tt>,
<tt>isFPOrFPVectorTy</tt> and <tt>isFPOrFPVectorTy</tt> respectively.</li>
<li><tt>llvm::Instruction::clone()</tt> no longer takes argument.</li>
<li><tt>raw_fd_ostream</tt>'s constructor now takes a flag argument, not individual
booleans (see <tt>include/llvm/Support/raw_ostream.h</tt> for details).</li>
<li>Some header files have been renamed:
