-
-<p>
-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>
-
-
-<h1>Requirements</h1>
-
-<dl>
-<dt>An x86 or amd64 processor. 64-bit mode is preferred.</dt>
-<dd>
- <p>
- Support for sse2 is strongly encouraged. Support for ssse3, and sse4.1 will
- yield the most efficient code. The less features the CPU has the more
- likely is that you ran into underperforming, buggy, or incomplete code.
- </p>
- <p>
- See /proc/cpuinfo to know what your CPU supports.
- </p>
-</dd>
-<dt>LLVM. Version 2.8 recommended. 2.6 or later required.</dt>
-<dd>
- <p>
- <b>NOTE</b>: LLVM 2.8 and earlier will not work on systems that support the
- Intel AVX extensions (e.g. Sandybridge). LLVM's code generator will
- fail when trying to emit AVX instructions. This was fixed in LLVM 2.9.
- </p>
- <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.

-</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

-<li> lp_test_blend: blending
-<li> lp_test_conv: SIMD vector conversion
-<li> lp_test_format: pixel unpacking/packing
-</ul>
-
-<p>
