-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.

+<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>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.
+</br>
+
+</ul>
+
+
+<a name="validation">
+<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.
