-
-Quick Start
------ -----
-
-Unzip the MesaLib, MesaGLUT, and MesaDemos ZIP files into the same
-directory.  The libs and demos build separately, so if you do not care
-about the demos or GLUT, you only need to unzip MesaLib.  If you unzip
-more than one ZIP file, they all need to be unzipped into the same
-directory.  Don't worry, you will not overwrite anything.
-
-The Windows build system uses Microsoft Visual Studio.  Project files
-for a specific version of Visual Studio are in their own directory in
-the top-level "windows" directory.  For example, Visual Studio 6 files
-are in windows/VC6.  If a directory does not exist for your version of
-Visual Studio, you can try importing the project files from an earlier
-version of Visual Studio.  At this time, project files exist for
-Version 6 and Version 7.  The code has been built with a beta version
-of Version 8 and it runs on 64-bit Windows.  If you want to try this,
-start by importing the VC7 files and create the 64-bit targets in the
-configuration manager.
-
-It is likely that the new and free Visual Studio Express can be used
-to build Mesa, but it hasn't been tried yet.  Start with the VC7
-project files.
-
-The project files to build the core Mesa library, Windows Mesa
-drivers, OSMesa, and GLU are in the mesa directory.  The project files
-to build GLUT and some demo programs are in the progs directory.
-
-Makefiles are no longer shipped or supported, but can be generated
-from the projects using Visual Studio.
-
-
-Windows Drivers
-------- -------
-
-At this time, only the GDI driver is known to work.  Most of the demos
-in progs/demos should work with this driver.
-
-Source code also exists in the tree for other drivers in
-src/mesa/drivers/windows, but the status of this code is unknown.
-
-The GDI driver operates basically by writing pixel spans into a DIB
-section and then blitting the DIB to the window.  The driver was
-recently cleaned up and rewitten and so may have bugs or may be
-missing some functionality.  The older versions of the CVS source may
-be useful in figuring out any problems, or report them to me.
-
-To build Mesa with the GDI driver, build the mesa, gdi, and glu
-projects in the Visual Studio workspace found at
-
-	windows/VC6/mesa/mesa.dsw
-or
-	windows/VC7/mesa/mesa.sln
-
-The osmesa DLL can also be built with the osmesa project.
-
-The build system creates a lib top-level directory and copies
-resulting LIB and DLL files to this lib directory.  The files are:
-
-	OPENGL32.LIB, GLU32.LIB, OSMESA32.LIB
-	OPENGL32.DLL, GLU32.DLL, OSMESA32.DLL
-
-If the MesaDemos ZIP file was extracted, the DLL files are also copied
-to the demos directory.  This facilitates running the demos as described
-below.
-
-
-GLUT and Demos
----- --- -----
-
-A Visual Studio workspace can be found at 
-
-	windows/VC6/progs/progs.dsw
-or
-	windows/VC7/progs/progs.sln
-
-It can be used to build GLUT and a few demos.  The GLUT lib and DLL
-are copied to the top-level lib directory, along with the Mesa libs.
-
-The demo build system expects to find the LIB files in the top level
-lib directory, so you must build the Mesa libs first.  The demo
-executables are placed in the demos directory, because some of them
-rely on data files found there.  Also, the Mesa lib DLL's were copied
-there by the Mesa lib build process.  Therefore, you should be able to
-simply run the demo executables from the demo directory.
-
-If you want to run the demos from the Visual Studio, you may have to
-change the startup directory and explicitly state where the executables are.
-
-You may also build all the demo programs by using a makefile.  Go to
-the progs/demos directory and make sure you have executed VCVARS32.BAT
-or whatever setup script is appropriate for your compiler.  Then,
-
-	nmake -f Makefile.win
-
-should build all the demos.
-
-
-Build System Notes
------ ------ -----
-
-VC6
----
-
-Visual Studio 6 does not recognize files with the .cc extension as C++
-language files, without a lot of unnatural tweaking.  So, the VC6
-build process uses custom build steps to compile these files in the
-GLU library.
-
-Two additional configurations are provided, Debug x86 and Release x86
-that activate the shader code compilation by defining SLANG_86.  It is
-unknown if and how this works.
-
-VC7
----
-
-The above-mentioned .cc problem does not exist in this version.
-
-
-General
--------
-
-After building, you can copy the above DLL files to a place in your
-PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
-in a system directory, place them in the same directory as the
-executable(s).  Be careful about accidentially overwriting files of
-the same name in the SYSTEM32 directory.
-
-The DLL files are built so that the external entry points use the
-stdcall calling convention.
-
-Static LIB files are not built.  The LIB files that are built with are
-the linker import files associated with the DLL files.
-
-The si-glu sources are used to build the GLU libs.  This was done
-mainly to get the better tessellator code.
-
-To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
-to the project settings.  You will also need to edit src/mesa.def to
-change all the gl* symbols to mgl*.  Because this is easy to do with a
-global replace operation in a text editor, no additional mangled
-version of mesa.def is maintained or shipped.
-
-If you have a Windows-related build problem or question, it is
-probably better to direct it to me (kschultz@users.sourceforge.net),
-rather than directly to the other Mesa developers.  I will help you as
-much as I can.  I also monitor the Mesa mailing lists and will answer
-questions in this area there as well.

+more than one ZIP file, they all need to be unzipped into the same
+directory.  Don't worry, you will not overwrite anything.
+
+The Windows build system uses Microsoft Visual Studio.  Project files
+for a specific version of Visual Studio are in their own directory in
+the top-level "windows" directory.  For example, Visual Studio 8 files
+are in windows/VC8.
+
+Support has been dropped for versions of Visual Studio prior to 8. The
+main reason is because Microsoft now provides a free compiler and
+developer environment.  Visual Studio Express can be found at
+
+http://msdn.microsoft.com/vstudio/express/visualc/default.aspx
+
+You'll also need the Platform SDK.  Instructions for obtaining and
+using the SDK with Visual Studio Express can be found at
+
+http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
+
+If you are stuck using VC6 or VC7, you may start with these project
+files, but you may need to modify them to reflect changes in the
+Mesa source code tree.  If you sucessfully update the project files,
+please submit them to the author of this document so that they may
+be included in the next distribution. 
+
+The project files to build the core Mesa library, Windows Mesa
+drivers, OSMesa, and GLU are in the mesa directory.  The project files
+to build GLUT and some demo programs are in the progs directory.
+
+Makefiles are no longer shipped or supported, but can be generated
+from the projects using Visual Studio.
+
+
+Windows Drivers
+------- -------
+
+At this time, only the GDI driver is known to work.  Most of the demos
+in progs/demos should work with this driver.
+
+Source code also exists in the tree for other drivers in
+src/mesa/drivers/windows, but the status of this code is unknown.
+
+The GDI driver operates basically by writing pixel spans into a DIB
+section and then blitting the DIB to the window.  The driver was
+recently cleaned up and rewitten and so may have bugs or may be
+missing some functionality.  The older versions of the CVS source may
+be useful in figuring out any problems, or report them to me.
+
+To build Mesa with the GDI driver, build the mesa, gdi, and glu
+projects in the Visual Studio workspace found at
+
+	windows/VC8/mesa/mesa.sln
+
+The osmesa DLL can also be built with the osmesa project.
+
+The build system creates a lib top-level directory and copies
+resulting LIB and DLL files to this lib directory.  The files are:
+
+	OPENGL32.LIB, GLU32.LIB, OSMESA32.LIB
+	OPENGL32.DLL, GLU32.DLL, OSMESA32.DLL
+
+If the MesaDemos ZIP file was extracted, the DLL files are also copied
+to the demos directory.  This facilitates running the demos as described
+below.
+
+
+GLUT and Demos
+---- --- -----
+
+A Visual Studio workspace can be found at 
+
+	windows/VC8/progs/progs.sln
+
+It can be used to build GLUT and a few demos.  The GLUT lib and DLL
+are copied to the top-level lib directory, along with the Mesa libs.
+
+The demo build system expects to find the LIB files in the top level
+lib directory, so you must build the Mesa libs first.  The demo
+executables are placed in the demos directory, because some of them
+rely on data files found there.  Also, the Mesa lib DLL's were copied
+there by the Mesa lib build process.  Therefore, you should be able to
+simply run the demo executables from the demo directory.
+
+If you want to run the demos from the Visual Studio, you may have to
+change the startup directory and explicitly state where the executables are.
+
+You may also build all the demo programs by using a makefile.  Go to
+the progs/demos directory and make sure you have executed VCVARS32.BAT
+or whatever setup script is appropriate for your compiler.  Then,
+
+	nmake -f Makefile.win
+
+should build all the demos.
+
+
+Build System Notes
+----- ------ -----
+
+VC6 (not actively supported)
+---
+
+Visual Studio 6 does not recognize files with the .cc extension as C++
+language files, without a lot of unnatural tweaking.  So, the VC6
+build process uses custom build steps to compile these files in the
+GLU library.
+
+Two additional configurations are provided, Debug x86 and Release x86
+that activate the shader code compilation by defining SLANG_86.  It is
+unknown if and how this works.
+
+VC7 (not actively supported)
+---
+
+The above-mentioned .cc problem does not exist in this version.
+
+VC8
+---
+
+No notes.
+
+
+General
+-------
+
+After building, you can copy the above DLL files to a place in your
+PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
+in a system directory, place them in the same directory as the
+executable(s).  Be careful about accidentially overwriting files of
+the same name in the SYSTEM32 directory.
+
+The DLL files are built so that the external entry points use the
+stdcall calling convention.
+
+Static LIB files are not built.  The LIB files that are built with are
+the linker import files associated with the DLL files.
+
+The si-glu sources are used to build the GLU libs.  This was done
+mainly to get the better tessellator code.
+
+To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
+to the project settings.  You will also need to edit src/mesa.def to
+change all the gl* symbols to mgl*.  Because this is easy to do with a
+global replace operation in a text editor, no additional mangled
+version of mesa.def is maintained or shipped.
+
+If you have a Windows-related build problem or question, it is
+probably better to direct it to me (kschultz@users.sourceforge.net),
+rather than directly to the other Mesa developers.  I will help you as
+much as I can.  I also monitor the Mesa mailing lists and will answer
+questions in this area there as well.

-			Mesa 6.5 Release Notes
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 6.5) designate new developmental releases.
-Even numbered versions (such as 6.4) designate stable releases.
-
-
-
-New Features
-------------
-
-OpenGL Shading language support
-   This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
-   GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions.  Most of
-   the work was done by Michal Krol.
-   There's probably a fair number of bugs since this is a pretty large,
-   complicated body of code.
-
-   The OpenGL 2.0 interface to these features will be implemented in a
-   future version of Mesa,
-
-GL_EXT_timer_query
-   Used to measure the time of OpenGL operations at high precision.
-   Only supported in the software/Xlib driver at this time.
-
-GL_EXT_packed_depth_stencil
-   Defines a new GL_DEPTH_STENCIL_EXT pixel format.
-
-GL_EXT_framebuffer_blit
-   A simplified glCopyPixels-like feature for copying pixel rectangles.
-
-GL_ARB_half_float_pixel
-   Adds a new half-precision floating point format for image transfers,
-   such as for glDrawPixels, glReadPixels, glTexImage, etc.
-
-
-
-Removed Extensions
-------------------
-
-The following extensions have been removed:
-
-  GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query.
-
-
-
-Known Issues
-------------
-
-Rendering to depth textures will not work.  Rendering to GL_DEPTH_STENCIL
-textures should work.
-
-
-
-Driver Interface Changes
-------------------------
-
-Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
-the two-sided versions: Driver.Stencil*Separate().
-
-Render-to-texture: The functions for rendering to textures have changed.
-
-
-
-To Do (someday) items
----------------------
- Switch to freeglut
- Increase MAX_DRAWBUFFERS
- Fix linux-glide target/driver.
- Fix lambda calculation for frag progs.
-
-
-
-Driver			Status

 <H1>Introduction</H1>
 
 <p>
-Mesa is a 3-D graphics library with an API which is very similar to
-that of <a href="http://www.opengl.org/" target="_parent">OpenGL</a>.*
-To the extent that Mesa utilizes the OpenGL command syntax or state
-machine, it is being used with authorization from <a
-href="http://www.sgi.com/" target="_parent">Silicon Graphics,
-Inc.</a>(SGI). However, the author does not possess an OpenGL license
-from SGI, and makes no claim that Mesa is in any way a compatible
-replacement for OpenGL or associated with SGI. Those who want a
-licensed implementation of OpenGL should contact a licensed
-vendor.
+Mesa is an open-source implementation of the
+<a href="http://www.opengl.org/" target="_parent">OpenGL</a> specification -
+a system for rendering interactive 3D graphics.
 </p>
 
 <p>
-Please do not refer to the library as <em>MesaGL</em> (for legal
-reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
-library</em>. <br>
+A variety of device drivers allows Mesa to be used in many different
+environments ranging from software emulation to complete hardware acceleration
+for modern GPUs.
 </p>

+<H1>Mesa 6.5.3 Release Notes / April 27, 2007</H1>
+
+<p>
+Mesa 6.5.3 is a development release with many changes and new features.
+Mesa 7.0 is expected to follow shortly.
+</p>
+
+
+<h2>MD5 checksums</h2>
+<pre>
+TBD
+</pre>
+
+
+<h2>Shared library numbering</h2>
+<p>
+Mesa 6.5.3 supports the OpenGL 2.0/2.1 API.  However, the (unix)
+shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx).
+Bumping the shared library version to 2.x would cause linking problems
+with existing OpenGL applications.  Since OpenGL 2.x is backward
+compatible with OpenGL 1.x the shared library version number doesn't
+have to be incremented (which would indicate an incompatible ABI).
+</p>
+<p>
+Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx
+for the same reason.
+</p>
+
+
+
+<h2>New features</h2>
+<ul>
+<li>OpenGL 2.0 and 2.1 API support.
+<li>Entirely new Shading Language code generator.  See the
+<a href="shading.html">Shading Language</a> page for more information.
+<li>Much faster software execution of vertex, fragment shaders.
+<li>New vertex buffer object (vbo) infrastructure
+<li>Updated glext.h file (version 39)
+<li>Updated glxext.h file (version 19)
+<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
+    "multiple render targets" are really supported.
+</ul>
+
+<h2>Bug fixes</h2>
+<ul>
+<li>Fog was errantly applied when a fragment shader was enabled (bug 9346)
+<li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
+<li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
+<li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
+<li>1D convolution state could effect 2D image transfers
+<li>Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
+<li>Fixed a number of framebuffer/renderbuffer reference counting bugs
+<li>Fixed a few bugs in software-emulated alpha planes
+<li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
+<li>Assorted DRI driver bug fixes.
+<li>Fixed a number of bugs that prevented "depth-peeling" rendering from working.
+</ul>
+
+
+<h2>Internal code changes</h2>
+<ul>
+<li>Old array_cache module replaced by new vbo module.  All geometry
+rendering is now cast in the form of vertex buffer objects.
+<li>Massive changes to the Shading Language compiler and related state.
+<li>Vertex/fragment shaders are compiled into GPU instructions and
+programs very similar to GL_ARB_vertex/fragment_program.
+<li>Vertex and fragment programs are executed with the same code now.
+<li>The SSE-optimized vertex program path has been removed since it didn't
+support more than 12 temp registers, didn't support branching/looping, etc.
+</ul>
+
+
+<h2>To Do (someday) items</h2>
+<ul>
+<li>Switch to freeglut
+<li>Fix linux-glide target/driver.
+<li>Improved lambda and derivative calculation for frag progs.
+</ul>
+
+
+<h2>Driver Status</h2>

+<h2>Unsupported Features</h2>
+
+<p>
+The following features of the shading language are not yet supported
+in Mesa:
+</p>
+
+<ul>
+<li>Dereferencing arrays with non-constant indexes
+<li>Comparison of user-defined structs
+<li>Linking of multiple shaders is not supported
+<li>gl_ClipVertex
+<li>The derivative functions such as dFdx() are not implemented
+<li>The inverse trig functions asin(), acos(), and atan() are not implemented
+<li>The gl_Color and gl_SecondaryColor varying vars are interpolated
+    without perspective correction
+</ul>
+
+<p>
+All other major features of the shading language should function.
+</p>
+
+
+<a name="notes">
+<h2>Implementation Notes</h2>
+
+<ul>
+<li>Shading language programs are compiled into low-level programs
+    very similar to those of GL_ARB_vertex/fragment_program.
+<li>All vector types (vec2, vec3, vec4, bvec2, etc) currently occupy full
+    float[4] registers.
+<li>Float constants and variables are packed so that up to four floats
+    can occupy one program parameter/register.
+<li>All function calls are inlined.
+<li>Shaders which use too many registers will not compile.
+<li>The quality of generated code is pretty good, register usage is fair.
+<li>Shader error detection and reporting of errors (InfoLog) is not
+    very good yet.
+<li>The ftransform() function doesn't necessarily match the results of
+    fixed-function transformation.
+</ul>
+
+<p>
+These issues will be addressed/resolved in the future.
+</p>
+
+
+<a name="hints">
+<h2>Programming Hints</h2>
+
+<ul>
+<li>Declare <em>in</em> function parameters as <em>const</em> whenever possible.
+    This improves the efficiency of function inlining.
+</li>
+<br>
+<li>To reduce register usage, declare variables within smaller scopes.
+    For example, the following code:
+<pre>
+    void main()
+    {
+       vec4 a1, a2, b1, b2;
+       gl_Position = expression using a1, a2.
+       gl_Color = expression using b1, b2;
+    }
+</pre>
+    Can be rewritten as follows to use half as many registers:
+<pre>
+    void main()
+    {
+       {
+          vec4 a1, a2;
+          gl_Position = expression using a1, a2.
+       }
+       {
+          vec4 b1, b2;
+          gl_Color = expression using b1, b2;
+       }
+    }
+</pre>
+    Alternately, rather than using several float variables, use
+    a vec4 instead.  Use swizzling and writemasks to access the
+    components of the vec4 as floats.
+</li>
+<br>
+<li>Use the built-in library functions whenever possible.
+    For example, instead of writing this:
+<pre>
+        float x = 1.0 / sqrt(y);
+</pre>
+    Write this:
+<pre>
+        float x = inversesqrt(y);
+</pre>
+<li>
+   Use ++i when possible as it's more efficient than i++
+</li>
+</ul>
+
+
+<a name="standalone">
+<h2>Stand-alone Compiler</h2>
+
+<p>
+A unique stand-alone GLSL compiler driver has been added to Mesa.
+<p>
+
+<p>
+The stand-alone compiler (like a conventional command-line compiler)
+is a tool that accepts Shading Language programs and emits low-level
+GPU programs.
+</p>
+
+<p>
+This tool is useful for:
+<p>
+<ul>
+<li>Inspecting GPU code to gain insight into compilation
+<li>Generating initial GPU code for subsequent hand-tuning
+<li>Debugging the GLSL compiler itself
+</ul>
+
+<p>
+To build the glslcompiler program (this will be improved someday):
+</p>
+<pre>
+    cd src/mesa
+    make libmesa.a
+    cd drivers/glslcompiler
+    make
+</pre>
+
+
+<p>
+Here's an example of using the compiler to compile a vertex shader and
+emit GL_ARB_vertex_program-style instructions:
+</p>
+<pre>
+    glslcompiler --arb --linenumbers --vs vertshader.txt
+</pre>
+<p>
+The output may look similar to this:
+</p>
+<pre>
+!!ARBvp1.0
+  0: MOV result.texcoord[0], vertex.texcoord[0];
+  1: DP4 temp0.x, state.matrix.mvp.row[0], vertex.position;
+  2: DP4 temp0.y, state.matrix.mvp.row[1], vertex.position;
+  3: DP4 temp0.z, state.matrix.mvp.row[2], vertex.position;
+  4: DP4 temp0.w, state.matrix.mvp.row[3], vertex.position;
+  5: MOV result.position, temp0;
+  6: END
+</pre>
+
+<p>
+Note that some shading language constructs (such as uniform and varying
+variables) aren't expressible in ARB or NV-style programs.
+Therefore, the resulting output is not always legal by definition of
+those program languages.
+</p>
+<p>
+Also note that this compiler driver is still under development.
+Over time, the correctness of the GPU programs, with respect to the ARB
+and NV languagues, should improve.
+</p>
+
+
+
+<a name="implementation">
+<h2>Compiler Implementation</h2>
+
+<p>
+The source code for Mesa's shading language compiler is in the
+<code>src/mesa/shader/slang/</code> directory.
+</p>
+
+<p>
+The compiler follows a fairly standard design and basically works as follows:
+</p>
+<ul>
+<li>The input string is tokenized (see grammar.c) and parsed
+(see slang_compiler_*.c) to produce an Abstract Syntax Tree (AST).
+The nodes in this tree are slang_operation structures
+(see slang_compile_operation.h).
+The nodes are decorated with symbol table, scoping and datatype information.
+<li>The AST is converted into an Intermediate representation (IR) tree
+(see the slang_codegen.c file).
+The IR nodes represent basic GPU instructions, like add, dot product,
+move, etc. 
+The IR tree is mostly a binary tree, but a few nodes have three or four
+children.
+In principle, the IR tree could be executed by doing an in-order traversal.
+<li>The IR tree is traversed in-order to emit code (see slang_emit.c).
+This is also when registers are allocated to store variables and temps.
+<li>In the future, a pattern-matching code generator-generator may be
+used for code generation.
+Programs such as L-BURG (Bottom-Up Rewrite Generator) and Twig look for
+patterns in IR trees, compute weights for subtrees and use the weights
+to select the best instructions to represent the sub-tree.
+<li>The emitted GPU instructions (see prog_instruction.h) are stored in a
+gl_program object (see mtypes.h).
+<li>When a fragment shader and vertex shader are linked (see slang_link.c)
+the varying vars are matched up, uniforms are merged, and vertex
+attributes are resolved (rewriting instructions as needed).
+</ul>
+
+<p>
+The final vertex and fragment programs may be interpreted in software
+(see prog_execute.c) or translated into a specific hardware architecture
+(see drivers/dri/i915/i915_fragprog.c for example).
+</p>
+
+<h3>Code Generation Options</h3>
+
+<p>
+Internally, there are several options that control the compiler's code
+generation and instruction selection.
+These options are seen in the gl_shader_state struct and may be set
+by the device driver to indicate its preferences:
+
+<pre>
+struct gl_shader_state
+{
+   ...
+   /** Driver-selectable options: */
+   GLboolean EmitHighLevelInstructions;
+   GLboolean EmitCondCodes;
+   GLboolean EmitComments;
+};
+</pre>
+
+<ul>
+<li>EmitHighLevelInstructions
+<br>
+This option controls instruction selection for loops and conditionals.
+If the option is set high-level IF/ELSE/ENDIF, LOOP/ENDLOOP, CONT/BRK
+instructions will be emitted.
+Otherwise, those constructs will be implemented with BRA instructions.
+</li>
+
+<li>EmitCondCodes
+<br>
+If set, condition codes (ala GL_NV_fragment_program) will be used for
+branching and looping.
+Otherwise, ordinary registers will be used (the IF instruction will
+examine the first operand's X component and do the if-part if non-zero).
+This option is only relevant if EmitHighLevelInstructions is set.
+</li>
+
+<li>EmitComments
+<br>
+If set, instructions will be annoted with comments to help with debugging.
+Extra NOP instructions will also be inserted.

+<h2>Compiler Validation</h2>
+
+<p>
+A new <a href="http://glean.sf.net" target="_parent">Glean</a> test has
+been create to exercise the GLSL compiler.
+</p>
+<p>
+The <em>glsl1</em> test runs over 150 sub-tests to check that the language
+features and built-in functions work properly.
+This test should be run frequently while working on the compiler to catch
+regressions.
+</p>
+<p>
+The test coverage is reasonably broad and complete but additional tests
+should be added.
