+ * Convert abstract syntax to to high-level intermediate reprensentation (HIR).

+ * During the conversion to HIR, the majority of the symantic checking is
+ * preformed on the program. This includes:
+ *
+ * * Symbol table management
+ * * Type checking
+ * * Function binding
+ *
+ * The majority of this work could be done during parsing, and the parser could
+ * probably generate HIR directly. However, this results in frequent changes
+ * to the parser code. Since we do not assume that every system this complier
+ * is built on will have Flex and Bison installed, we have to store the code
+ * generated by these tools in our version control system. In other parts of
+ * the system we've seen problems where a parser was changed but the generated
+ * code was not committed, merge conflicts where created because two developers
+ * had slightly different versions of Bison installed, etc.
+ *
+ * I have also noticed that running Bison generated parsers in GDB is very
+ * irritating. When you get a segfault on '$$ = $1->foo', you can't very
+ * well 'print $1' in GDB.
+ *
+ * As a result, my preference is to put as little C code as possible in the
+ * parser (and lexer) sources.

+ * GLSL linker implementation
+ *
+ * Given a set of shaders that are to be linked to generate a final program,
+ * there are three distinct stages.
+ *
+ * In the first stage shaders are partitioned into groups based on the shader
+ * type. All shaders of a particular type (e.g., vertex shaders) are linked
+ * together.
+ *
+ * - Undefined references in each shader are resolve to definitions in
+ * another shader.
+ * - Types and qualifiers of uniforms, outputs, and global variables defined
+ * in multiple shaders with the same name are verified to be the same.
+ * - Initializers for uniforms and global variables defined
+ * in multiple shaders with the same name are verified to be the same.
+ *
+ * The result, in the terminology of the GLSL spec, is a set of shader
+ * executables for each processing unit.
+ *
+ * After the first stage is complete, a series of semantic checks are performed
+ * on each of the shader executables.
+ *
+ * - Each shader executable must define a \c main function.
+ * - Each vertex shader executable must write to \c gl_Position.
+ * - Each fragment shader executable must write to either \c gl_FragData or
+ * \c gl_FragColor.
+ *
+ * In the final stage individual shader executables are linked to create a
+ * complete exectuable.
+ *
+ * - Types of uniforms defined in multiple shader stages with the same name
+ * are verified to be the same.
+ * - Initializers for uniforms defined in multiple shader stages with the
+ * same name are verified to be the same.
+ * - Types and qualifiers of outputs defined in one stage are verified to
+ * be the same as the types and qualifiers of inputs defined with the same
+ * name in a later stage.

+/**
+ * \file opt_tree_grafting.cpp
+ *
+ * Takes assignments to variables that are dereferenced only once and
+ * pastes the RHS expression into where the variable is dereferenced.
+ *
+ * In the process of various operations like function inlining and
+ * tertiary op handling, we'll end up with our expression trees having
+ * been chopped up into a series of assignments of short expressions
+ * to temps. Other passes like ir_algebraic.cpp would prefer to see
+ * the deepest expression trees they can to try to optimize them.
+ *
+ * This is a lot like copy propagaton. In comparison, copy
+ * propagation only acts on plain copies, not arbitrary expressions on
+ * the RHS. Generally, we wouldn't want to go pasting some
+ * complicated expression everywhere it got used, though, so we don't
+ * handle expressions in that pass.
+ *
+ * The hard part is making sure we don't move an expression across
+ * some other assignments that would change the value of the
+ * expression. So we split this into two passes: First, find the
+ * variables in our scope which are written to once and read once, and
+ * then go through basic blocks seeing if we find an opportunity to
+ * move those expressions safely.

+ * These functions are compiled into each DRI driver so libGL.so knows nothing

+ * <LI> Structures to represent most GL state </LI>
+ * <LI> State set/get functions </LI>
+ * <LI> Display lists </LI>
+ * <LI> Texture unit, object and image handling </LI>
+ * <LI> Matrix and attribute stacks </LI>
+ * </UL>
+ *
+ * Other modules are responsible for API dispatch, vertex transformation,
+ * point/line/triangle setup, rasterization, vertex array caching,
+ * vertex/fragment programs/shaders, etc.

+ * There are three large Mesa data types/classes which are meant to be
+ * used by device drivers:
+ * - struct gl_context: this contains the Mesa rendering state
+ * - struct gl_config: this describes the color buffer (RGB vs. ci), whether or not
+ * there's a depth buffer, stencil buffer, etc.
+ * - struct gl_framebuffer: contains pointers to the depth buffer, stencil buffer,

+ * These types should be encapsulated by corresponding device driver
