<h5>Overview:</h5>
<p>A union type describes an object with size and alignment suitable for
an object of any one of a given set of types (also known as an "untagged"
union). It is similar in concept and usage to a
<a href="#t_struct">struct</a>, except that all members of the union
have an offset of zero. The elements of a union may be any type that has a
size. Unions must have at least one member - empty unions are not allowed.
</p>
<p>The size of the union as a whole will be the size of its largest member,
and the alignment requirements of the union as a whole will be the largest
alignment requirement of any member.</p>
<p>Unions members are accessed using '<tt><a href="#i_load">load</a></tt> and
'<tt><a href="#i_store">store</a></tt>' by getting a pointer to a field with
the '<tt><a href="#i_getelementptr">getelementptr</a></tt>' instruction.
Since all members are at offset zero, the getelementptr instruction does
not affect the address, only the type of the resulting pointer.</p>

<p>
LLVM's "eager" JIT compiler is safe to use in threaded programs. Multiple
threads can call <tt>ExecutionEngine::getPointerToFunction()</tt> or
<tt>ExecutionEngine::runFunction()</tt> concurrently, and multiple threads can
run code output by the JIT concurrently. The user must still ensure that only
one thread accesses IR in a given <tt>LLVMContext</tt> while another thread
might be modifying it. One way to do that is to always hold the JIT lock while
accessing IR outside the JIT (the JIT <em>modifies</em> the IR by adding
<tt>CallbackVH</tt>s). Another way is to only
call <tt>getPointerToFunction()</tt> from the <tt>LLVMContext</tt>'s thread.

<p>When the JIT is configured to compile lazily (using

<a href="http://llvm.org/bugs/show_bug.cgi?id=5184">race condition</a> in
updating call sites after a function is lazily-jitted. It's still possible to
use the lazy JIT in a threaded program if you ensure that only one thread at a
time can call any particular lazy stub and that the JIT lock guards any IR
access, but we suggest using only the eager JIT in threaded programs.

The LLVM Machine Code (MC) Toolkit project is a (very early) effort to build
better tools for dealing with machine code, object file formats, etc. The idea
is to be able to generate most of the target specific details of assemblers and
disassemblers from existing LLVM target .td files (with suitable enhancements),
and to build infrastructure for reading and writing common object file formats.
One of the first deliverables is to build a full assembler and integrate it into
the compiler, which is predicted to substantially reduce compile time in some
scenarios.
</p>
<p>In the LLVM 2.6 timeframe, the MC framework has grown to the point where it
can reliably parse and pretty print (with some encoding information) a
darwin/x86 .s file successfully, and has the very early phases of a Mach-O
assembler in progress. Beyond the MC framework itself, major refactoring of the
LLVM code generator has started. The idea is to make the code generator reason
about the code it is producing in a much more semantic way, rather than a
textual way. For example, the code generator now uses MCSection objects to
represent section assignments, instead of text strings that print to .section
directives.</p>
<p>MC is an early and ongoing project that will hopefully continue to lead to
many improvements in the code generator and build infrastructure useful for many
other situations.

<li>Targets can now specify register allocation hints through
<tt>MachineRegisterInfo::setRegAllocationHint</tt>. A regalloc hint consists
of hint type and physical register number. A hint type of zero specifies a
register allocation preference. Other hint type values are target specific
which are resolved by <tt>TargetRegisterInfo::ResolveRegAllocHint</tt>. An
example is the ARM target which uses register hints to request that the
register allocator provide an even / odd register pair to two virtual

<ul>
<li>All uses of <tt>hash_set</tt> and <tt>hash_map</tt> have been removed from
the LLVM tree and the wrapper headers have been removed.</li>
<li>The llvm/Streams.h and <tt>DOUT</tt> member of Debug.h have been removed. The
<tt>llvm::Ostream</tt> class has been completely removed and replaced with
uses of <tt>raw_ostream</tt>.</li>
<li>LLVM's global uniquing tables for <tt>Type</tt>s and <tt>Constant</tt>s have
been privatized into members of an <tt>LLVMContext</tt>. A number of APIs
now take an <tt>LLVMContext</tt> as a parameter. To smooth the transition
for clients that will only ever use a single context, the new
<tt>getGlobalContext()</tt> API can be used to access a default global
context which can be passed in any and all cases where a context is
required.
<li>The <tt>getABITypeSize</tt> methods are now called <tt>getAllocSize</tt>.</li>
<li>The <tt>Add</tt>, <tt>Sub</tt> and <tt>Mul</tt> operators are no longer
overloaded for floating-point types. Floating-point addition, subtraction
and multiplication are now represented with new operators <tt>FAdd</tt>,
<tt>FSub</tt> and <tt>FMul</tt>. In the <tt>IRBuilder</tt> API,
<tt>CreateAdd</tt>, <tt>CreateSub</tt>, <tt>CreateMul</tt> and
<tt>CreateNeg</tt> should only be used for integer arithmetic now;
<tt>CreateFAdd</tt>, <tt>CreateFSub</tt>, <tt>CreateFMul</tt> and

<li>The <tt>DynamicLibrary</tt> class can no longer be constructed, its functionality has
moved to static member functions.</li>
<li><tt>raw_fd_ostream</tt>'s constructor for opening a given filename now
takes an extra <tt>Force</tt> argument. If <tt>Force</tt> is set to
<tt>false</tt>, an error will be reported if a file with the given name
already exists. If <tt>Force</tt> is set to <tt>true</tt>, the file will
be silently truncated (which is the behavior before this flag was
added).</li>
<li><tt>SCEVHandle</tt> no longer exists, because reference counting is no
longer done for <tt>SCEV*</tt> objects, instead <tt>const SCEV*</tt>
should be used.</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>Many APIs, notably <tt>llvm::Value</tt>, now use the <tt>StringRef</tt>
and <tt>Twine</tt> classes instead of passing <tt>const char*</tt>
or <tt>std::string</tt>, as described in
the <a href="ProgrammersManual.html#string_apis">Programmer's Manual</a>. Most
clients should be unaffected by this transition, unless they are used to
<tt>Value::getName()</tt> returning a string. Here are some tips on updating to
2.6:
<ul>
<li><tt>getNameStr()</tt> is still available, and matches the old
behavior. Replacing <tt>getName()</tt> calls with this is an safe option,
although more efficient alternatives are now possible.</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>
<li>If you were just relying on <tt>getName()</tt> being able to be sent to
a <tt>std::ostream</tt>, consider migrating
to <tt>llvm::raw_ostream</tt>.</li>
<li>If you were using <tt>getName().c_str()</tt> to get a <tt>const
char*</tt> pointer to the name, you can use <tt>getName().data()</tt>.
Note that this string (as before), may not be the entire name if the
name contains embedded null characters.</li>
<li>FIXME: Debug info has been totally redone. Add pointers to new APIs. Substantial caveats about compatibility of .ll and .bc files.</li>
<li>If you were using <tt>operator +</tt> on the result of <tt>getName()</tt> and
treating the result as an <tt>std::string</tt>, you can either
use <tt>Twine::str</tt> to get the result as an <tt>std::string</tt>, or
could move to a <tt>Twine</tt> based design.</li>
<li>The <tt>llvm/Support/DataTypes.h</tt> header has moved
to <tt>llvm/System/DataTypes.h</tt>.</li>
<li><tt>isName()</tt> should be replaced with comparison
against <tt>getName()</tt> (this is now efficient).

<li>The registration interfaces for backend Targets has changed (what was
previously <tt>TargetMachineRegistry</tt>). For backend authors, see the <a
