<p>This document contains the release notes for the LLVM compiler
-infrastructure, release 1.2. Here we describe the status of LLVM, including any
+infrastructure, release 1.4. Here we describe the status of LLVM, including any
known problems and bug fixes from the previous release. The most up-to-date
version of this document can be found on the <a

-This is the third public release of the LLVM compiler infrastructure. This
-release incorporates several <a href="#newfeatures">new features</a> (including
-exception handling support for the native code generators, the start of a
-source-level debugger, and profile guided optimizer components), many <a
-href="#qualityofimp">speedups</a> and <a href="#codequality">code quality</a>
-improvements, documentation improvements, and a small collection of important <a

-<p><B> FIXME: UPDATE: </b>
-At this time, LLVM is known to correctly compile and run all C
-& C++ SPEC CPU2000 benchmarks, the Olden benchmarks, and the Ptrdist
-benchmarks. It has also been used to compile <b>many</b> other programs. LLVM
-now also works with a broad variety of C++ programs, though it has still
-received less testing than the C front-end.

<a name="newfeatures">This release implements the following new features:</a>
</div>
+<div class="doc_text">
+
<ol>
-<li><a href="SourceLevelDebugging.html">A new LLVM source-level debugger has been started.</a></li>
-<li>LLVM 1.2 encodes bytecode files for large programs in 10-30% less space.</li>
-<li>LLVM can now feed profile information back into optimizers for Profile Guided Optimization, includes a simple basic block reordering pass, and supports edge profiling as well as function and block-level profiling.</li>
-<li>The LLVM JIT lazily initializes global variables, reducing startup time for programs with lots of globals (like C++ programs).</li>
-
-<li>The build and installation infrastructure in this release is dramatically
-improved. There is now an <a
-href="http://llvm.cs.uiuc.edu/PR105"><tt>autoconf/AutoRegen.sh</tt> script</a>
-that you can run to rebuild the <tt>configure</tt> script and its associated
-files as well as beta support for "<a
-href="http://llvm.cs.uiuc.edu/PR208">make</a> <a
-href="http://llvm.cs.uiuc.edu/PR220">install</a>" and <a
-href="http://llvm.cs.uiuc.edu/PR203">RPM package generation</a>.</li>
-
-<li>The "tblgen" tool is <a href="TableGenFundamentals.html">now documented</a>.</li>
-<li>The target-independent code generator got several improvements:
-<ul>
- <li>It can now fold spill code into instructions (on targets that support it).</li>
- <li>A generic machine code spiller/rewriter was added. It provides an API for
- global register allocators to eliminate virtual registers and add the
- appropriate spill code.</li>
- <li>The represenation of machine code basic blocks is more efficient and has
- an easier to use interface.</li>
-</ul>
-</li>
-<li><a href="http://llvm.cs.uiuc.edu/PR253">LLVM now no longer depends on the boost library</a>.</li>
-<li>The X86 backend now generates <b>substantially</b> better native code, and is faster.</li>
-<li>The C backend has been turned moved from the "llvm-dis" tool to the "llc"
-tool. You can activate it with "<tt>llc -march=c foo.bc -o foo.c</tt>".</li>
-<li>LLVM includes a new interprocedural optimization that marks global variables
-"constant" when they are provably never written to.</li>
-<li>LLVM now includes a new interprocedural optimization that converts small "by reference" arguments to "by value" arguments, which is often improve the performance of C++ programs substantially.</li>
+ <li>The test/Programs hierarchy <a href="http://llvm.cs.uiuc.edu/PR257">has
+ been moved out of the main LLVM tree</a> into a separate CVS repo and
+ tarball.</li>
+ <li>LLVM now optimizes global variables significantly more than it did
+ before.</li>
+ <li>LLVM now includes the new '<tt>undef</tt>' value and <a
+ href="LangRef.html#i_unreachable"><tt>unreachable</tt></a> instruction,
+ which give the optimizer more information about the behavior of the
+ program.</li>

-<p>LLVM has been extensively tested on Intel and AMD machines running Red
-Hat Linux and FreeBSD. It has also been tested on Sun UltraSPARC workstations running Solaris 8.
-Additionally,
-LLVM works on Mac OS X 10.3 and above, but only with the C backend or
-interpreter (no native backend for the PowerPC is available yet).
-The core LLVM infrastructure uses "autoconf" for portability, so hopefully we
-work on more platforms than that. However, it is likely that we
-missed something and that minor porting is required to get LLVM to work on
-new platforms. We welcome portability patches and error messages.</p>
+<p>LLVM is known to work in the following platforms:</p>
+
+<ul>
+<li>Intel and AMD machines running Red Hat Linux and FreeBSD (and probably
+ other unix-like systems).</li>
+<li>Sun UltraSPARC workstations running Solaris 8.</li>
+<li>Intel and AMD machines running on Win32 with the Cygwin libraries.</li>
+<li>PowerPC-based Mac OS X boxes, running 10.2 and above. Note that no JIT
+support is available yet, and LLC support is beta. The C backend can be used
+to produce stable code for this platform.</li>
+</ul>
+
+<p>The core LLVM infrastructure uses
+<a href="http://www.gnu.org/software/autoconf/">GNU autoconf</a> to adapt itself
+to the machine and operating system on which it is built. However, minor
+porting may be required to get LLVM to work on new platforms. We welcome your
+portability patches and reports of successful builds or error messages.</p>
+
+<p>Note that the LLVM build system does not currently support directories with
+spaces on them when running on Win32/cygwin. We strongly recommend running
+LLVM and the C frontend out of a top-level directory without spaces (e.g.,
+<tt>/cygdrive/c/llvm</tt>). Also, make sure to install <b>all</b> of the
+cygwin packages. By default, many important tools are not installed that
+are needed by the LLVM build process or test suite (e.g., /bin/time). Finally,
+please make sure that there are no directories with spaces in them in your
+PATH environment variable.</p>
