disable printing shader program debug info

Since the recent renderbuffer refcounting fixes it's no longer sufficient to
just remove the old renderbuffer from the framebuffer and then add the new one
because the former may decrease the reference count to 0 and delete the old
renderbuffer.

-			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-  GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query.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-Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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.
-
-
-

-<H1>CVS Branch Information</H1>
-
-<p>
-At any given time, there may be several active branches in Mesa's
-CVS repository.
-
-Generally, the CVS trunk contains the latest development (unstable)
-code while a CVS branch has the latest stable code.
-</p>
-
-<p>
-Currently (Oct 2004), the trunk is the Mesa 6.3 development code
-while the mesa_6_2_branch branch has the stable Mesa 6.2.x code.
-</p>
-
-<p>
-Mesa releases use an even/odd numbering scheme to represent stable/development
-releases.
-
-For example, Mesa 6.2 (0 is considered even) is a stable release while
-Mesa 6.3 is a development release.
-</p>
-
-<p>
-To checkout a specific CVS branch pass <code>-r</code> and
-the branch tag after your CVS command.
-
-For example <code>cvs checkout -r mesa_6_2_branch Mesa</code> will
-checkout the 6.2 branch and <code>cvs update -r
-mesa_6_2_branch</code> will convert your current CVS tree to the 6.2
-branch.
-
-Consult <a href="http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54"
-target="_parent">http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54</a>
-for more on branching in CVS.
-</p>
-
-<p>
-To see a list of all the CVS branches run <code>cvs log README</code> (or any
-other file) and look for the section labeled <code>symbolic names</code>.
-You'll see something like this:
-</p>
-
-<pre>  symbolic names:
-        mesa_4_0: 1.3
-        mesa_4_0_branch: 1.3.0.6
-        mesa_3_5: 1.3

+<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>User-defined structs
+<li>Linking of multiple shaders is not supported
+<li>Integer operations are not fully implemented (most are implemented
+    as floating point).
+<li>gl_ClipVertex
+</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>There are known memory leaks in the compiler.
+</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>
+</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>
