-The Gallium llvmpipe driver is a software rasterizer that uses LLVM to
-do runtime code generation.
-Shaders, point/line/triangle rasterization and vertex processing are
-implemented with LLVM IR which is translated to x86 or x86-64 machine
-code.
-Also, the driver is multithreaded to take advantage of multiple CPU cores
-(up to 8 at this time).
-It's the fastest software rasterizer for Mesa.

-   <p>
-   For Linux, on a recent Debian based distribution do:
-   </p>
-<pre>
-     aptitude install llvm-dev
-</pre>
-   For a RPM-based distribution do:
-   </p>
-<pre>
-     yum install llvm-devel
-</pre>
-
-   <p>
-   For Windows download pre-built MSVC 9.0 or MinGW binaries from
-   http://people.freedesktop.org/~jrfonseca/llvm/ and set the LLVM environment
-   variable to the extracted path.
-   </p>
-
-   <p>
-   For MSVC there are two set of binaries: llvm-x.x-msvc32mt.7z and
-   llvm-x.x-msvc32mtd.7z .
-   </p>
-
-   <p>
-   You have to set the LLVM=/path/to/llvm-x.x-msvc32mtd env var when passing
-   debug=yes to scons, and LLVM=/path/to/llvm-x.x-msvc32mt when building with
-   debug=no. This is necessary as LLVM builds as static library so the chosen
-   MS CRT must match.

-<h1>Building</h1>
-
-To build everything on Linux invoke scons as:
-
-<pre>
-  scons build=debug libgl-xlib
-</pre>
-
-Alternatively, you can build it with GNU make, if you prefer, by invoking it as
-
-<pre>
-  make linux-llvm
-</pre>
-
-but the rest of these instructions assume that scons is used.
-
-For windows is everything the except except the winsys:
-
-<pre>
-  scons build=debug libgl-gdi
-</pre>
-
-
-<h1>Using</h1>
-
-On Linux, building will create a drop-in alternative for libGL.so into
-
-<pre>
-  build/foo/gallium/targets/libgl-xlib/libGL.so
-</pre>
-or
-<pre>
-  lib/gallium/libGL.so
-</pre>
-
-To use it set the LD_LIBRARY_PATH environment variable accordingly.
-
-For performance evaluation pass debug=no to scons, and use the corresponding
-lib directory without the "-debug" suffix.
-
-On Windows, building will create a drop-in alternative for opengl32.dll. To use
-it put it in the same directory as the application. It can also be used by
-replacing the native ICD driver, but it's quite an advanced usage, so if you
-need to ask, don't even try it.
-
-
-<h1>Profiling</h1>
-
-To profile llvmpipe you should pass the options
-
-<pre>
-  scons build=profile <same-as-before>
-</pre>
-
-This will ensure that frame pointers are used both in C and JIT functions, and
-that no tail call optimizations are done by gcc.
-
-To better profile JIT code you'll need to build LLVM with oprofile integration.

-
-  make -C "$build_dir"
-  make -C "$build_dir" install
-
-  find "$install_dir/lib" -iname '*.a' -print0 | xargs -0 strip --strip-debug
-</pre>
-
-The you should define
-
-<pre>
-  export LLVM=/path/to/llvm-2.6-profile
-</pre>
-
-and rebuild.
-
-
-<h1>Unit testing</h1>
-
-<p>
-Building will also create several unit tests in
-build/linux-???-debug/gallium/drivers/llvmpipe:
-</p>
-
-</ul>
-<li> lp_test_blend: blending
-<li> lp_test_conv: SIMD vector conversion
-<li> lp_test_format: pixel unpacking/packing
-</ul>
-
-<p>
-Some of this tests can output results and benchmarks to a tab-separated-file
-for posterior analysis, e.g.:
-</p>
-<pre>
-  build/linux-x86_64-debug/gallium/drivers/llvmpipe/lp_test_blend -o blend.tsv
-</pre>
-
-
-<h1>Development Notes</h1>

-  When looking to this code by the first time start in lp_state_fs.c, and

-</li>
-<li>
-  The driver-independent parts of the LLVM / Gallium code are found in

+	 For Windows you will need to build LLVM from source with MSVC or MINGW
+	 (either natively or through cross compilers) and CMake, and set the LLVM
+	 environment variable to the directory you installed it to.
+
+   LLVM will be statically linked, so when building on MSVC it needs to be
+   built with a matching CRT as Mesa, and you'll need to pass
+   -DLLVM_USE_CRT_RELEASE=MTd for debug and checked builds,
+   -DLLVM_USE_CRT_RELEASE=MTd for profile and release builds.
+
+   You can build only the x86 target by passing -DLLVM_TARGETS_TO_BUILD=X86
+   to cmake.
