+- Implement AST-to-HIR conversion of discard instructions.

+
+- Handle constant expressions of (struct == struct)
+
+- Handle constant expressions of (struct != struct)
+
+- Add support to ir_constant for array constants Arrays can only be
+  - declared 'const' in GLSL 1.20+.  This is because there are no
+    array constructors in GLSL 1.10, and any variable declared as
+    'const' must have an initializer.
+
+- Handle constant expressions of (array == array)
+
+- Handle constant expressions of (array != array)
+
+- Treat built-in functions with constant parameters as constant expressions.
+  - Rewrite all built-in functions return a single expression.
+  - Modify the HIR generator for functions to automatically inline built-in
+    functions durning translation.
+  - Care must be taken to handle both the 1.10 rules and the 1.20+ rules.  In
+    1.10, built-in functions cannot be constant expressions.
+
+- Detect non-void functions that lack a return statement
+
+- Detect return statements with a type not matching the funciton's
+  return type.
+
+- Handle over-riding built-in functions
+  - Is the overload per-compilation unit or per-linked shader?
+
+- Handle redeclaration of built-in variables
+  - Handle addition of qualifiers such as 'invariant' or 'centroid'.
+  - Handle resizing of arrays.
+  - Other?  We'll have to look at the spec.
+
+- Improve handling of constants and their initializers.  Constant initializers
+  should never generate any code.  This is trival for scalar constants.  It is
+  also trivial for arrays, matrices, and vectors that are accessed with
+  constant index values.  For others it is more complicated.  Perhaps these
+  cases should be silently converted to uniforms?
+
+1.30 features:
+
+- Implement AST-to-HIR conversion of bit-shift operators.
+
+- Implement AST-to-HIR conversion of bit-wise {&,|,^,!} operators.
+
+- Implement AST-to-HIR conversion of switch-statements
+  - switch
+  - case
+  - Update break to correcly handle mixed nexting of switch-statements
+    and loops.
+
+- Handle currently unsupported constant expression types
+  - ir_unop_bit_not
+  - ir_binop_mod
+  - ir_binop_lshift
+  - ir_binop_rshift
+  - ir_binop_bit_and
+  - ir_binop_bit_xor

+ * \file ast_to_hir.c
+ * 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.

+glcpp -- GLSL "C" preprocessor
+
+This is a simple preprocessor designed to provide the preprocessing
+needs of the GLSL language. The requirements for this preprocessor are
+specified in the GLSL 1.30 specification availble from:
+
+http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.08.pdf
+
+This specification is not precise on some semantics, (for example,
+#define and #if), defining these merely "as is standard for C++
+preprocessors". To fill in these details, I've been using the C99
+standard (for which I had a convenient copy) as available from:
+
+http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf
+
+Known limitations
+-----------------
+Macro invocations cannot include embedded newlines.
+
+The __LINE__, __FILE__, and __VERSION__ macros are not yet supported.
+
+The argument of the 'defined' operator cannot yet include enclosing
+parentheses.
+
+The #error, #pragma, #extension, #version, and #line macros are not
+yet supported.
+
+A file that ends with a function-like macro name as the last
+non-whitespace token will result in a parse error, (where it should be
+passed through as is).
\ No newline at end of file

+/**
+ * Base class of hierarchical visitors of IR instruction trees
+ *
+ * Hierarchical visitors differ from traditional visitors in a couple of
+ * important ways.  Rather than having a single \c visit method for each
+ * subclass in the composite, there are three kinds of visit methods.
+ * Leaf-node classes have a traditional \c visit method.  Internal-node
+ * classes have a \c visit_enter method, which is invoked just before
+ * processing child nodes, and a \c visit_leave method which is invoked just
+ * after processing child nodes.
+ *
+ * In addition, each visit method and the \c accept methods in the composite
+ * have a return value which guides the navigation.  Any of the visit methods
+ * can choose to continue visiting the tree as normal (by returning \c
+ * visit_continue), terminate visiting any further nodes immediately (by
+ * returning \c visit_stop), or stop visiting sibling nodes (by returning \c
+ * visit_continue_with_parent).
+ *
+ * These two changes combine to allow nagivation of children to be implemented
+ * in the composite's \c accept method.  The \c accept method for a leaf-node
+ * class will simply call the \c visit method, as usual, and pass its return
+ * value on.  The \c accept method for internal-node classes will call the \c
+ * visit_enter method, call the \c accpet method of each child node, and,
+ * finally, call the \c visit_leave method.  If any of these return a value
+ * other that \c visit_continue, the correct action must be taken.
+ *
+ * The final benefit is that the hierarchical visitor base class need not be
+ * abstract.  Default implementations of every \c visit, \c visit_enter, and
+ * \c visit_leave method can be provided.  By default each of these methods
+ * simply returns \c visit_continue.  This allows a significant reduction in
+ * derived class code.
+ *
+ * For more information about hierarchical visitors, see:
+ *
+ *    http://c2.com/cgi/wiki?HierarchicalVisitorPattern
+ *    http://c2.com/cgi/wiki?HierarchicalVisitorDiscussion

+ * 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 list.h
+ * \brief Doubly-linked list abstract container type.
+ *
+ * Each doubly-linked list has a sentinal head and tail node.  These nodes
+ * contain no data.  The head sentinal can be identified by its \c prev
+ * pointer being \c NULL.  The tail sentinal can be identified by its
+ * \c next pointer being \c NULL.
+ *
+ * A list is empty if either the head sentinal's \c next pointer points to the
+ * tail sentinal or the tail sentinal's \c prev poiner points to the head
+ * sentinal.
+ *
+ * Instead of tracking two separate \c node structures and a \c list structure
+ * that points to them, the sentinal nodes are in a single structure.  Noting
+ * that each sentinal node always has one \c NULL pointer, the \c NULL
+ * pointers occupy the same memory location.  In the \c list structure
+ * contains a the following:
+ *
+ *   - A \c head pointer that represents the \c next pointer of the
+ *     head sentinal node.
+ *   - A \c tail pointer that represents the \c prev pointer of the head
+ *     sentinal node and the \c next pointer of the tail sentinal node.  This
+ *     pointer is \b always \c NULL.
+ *   - A \c tail_prev pointer that represents the \c prev pointer of the
+ *     tail sentinal node.
+ *
+ * Therefore, if \c head->next is \c NULL or \c tail_prev->prev is \c NULL,
+ * the list is empty.
+ *
+ * To anyone familiar with "exec lists" on the Amiga, this structure should
+ * be immediately recognizable.  See the following link for the original Amiga
+ * operating system documentation on the subject.
+ *
