+- Detect code paths in non-void functions that don't reach a return statement
+
+- 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?
+
+- Implement support for ir_binop_dot in ir_algebraic.cpp. Perform
+ transformations such as "dot(v, vec3(0.0, 1.0, 0.0))" -> v.y.

+- 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

+- Handle currently unsupported constant expression types

+- Implement support for 1.30 style shadow compares which only return a float
+ instead of a vec4.
+
+- Implement support for gl_ClipDistance. This is non-trivial because
+ gl_ClipDistance is exposed as a float[8], but all hardware actually
+ implements it as vec4[2]. \ No newline at end of file

-/**
- * \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.

-/**
- * \file linker.cpp
- * 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.

+ * 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 lower_instructions.cpp
+ *
+ * Many GPUs lack native instructions for certain expression operations, and
+ * must replace them with some other expression tree. This pass lowers some
+ * of the most common cases, allowing the lowering code to be implemented once
+ * rather than in each driver backend.
+ *
+ * Currently supported transformations:
+ * - SUB_TO_ADD_NEG
+ * - DIV_TO_MUL_RCP
+ * - EXP_TO_EXP2
+ * - POW_TO_EXP2
+ * - LOG_TO_LOG2
+ * - MOD_TO_FRACT
+ *
+ * SUB_TO_ADD_NEG:
+ * ---------------
+ * Breaks an ir_binop_sub expression down to add(op0, neg(op1))
+ *
+ * This simplifies expression reassociation, and for many backends
+ * there is no subtract operation separate from adding the negation.
+ * For backends with native subtract operations, they will probably
+ * want to recognize add(op0, neg(op1)) or the other way around to
+ * produce a subtract anyway.
+ *
+ * DIV_TO_MUL_RCP:
+ * ---------------
+ * Breaks an ir_unop_div expression down to op0 * (rcp(op1)).
+ *
+ * Many GPUs don't have a divide instruction (945 and 965 included),
+ * but they do have an RCP instruction to compute an approximate
+ * reciprocal. By breaking the operation down, constant reciprocals
+ * can get constant folded.
+ *
+ * EXP_TO_EXP2 and LOG_TO_LOG2:
+ * ----------------------------
+ * Many GPUs don't have a base e log or exponent instruction, but they
+ * do have base 2 versions, so this pass converts exp and log to exp2
+ * and log2 operations.
+ *
+ * POW_TO_EXP2:
+ * -----------
+ * Many older GPUs don't have an x**y instruction. For these GPUs, convert
+ * x**y to 2**(y * log2(x)).
+ *
+ * MOD_TO_FRACT:
+ * -------------
+ * Breaks an ir_unop_mod expression down to (op1 * fract(op0 / op1))
+ *
+ * Many GPUs don't have a MOD instruction (945 and 965 included), and
+ * if we have to break it down like this anyway, it gives an
+ * opportunity to do things like constant fold the (1.0 / op1) easily.

+/**
+ * \file lower_jumps.cpp
+ *
+ * This pass lowers jumps (break, continue, and return) to if/else structures.
+ *
+ * It can be asked to:
+ * 1. Pull jumps out of ifs where possible
+ * 2. Remove all "continue"s, replacing them with an "execute flag"
+ * 3. Replace all "break" with a single conditional one at the end of the loop
+ * 4. Replace all "return"s with a single return at the end of the function,
+ * for the main function and/or other functions
+ *
+ * Applying this pass gives several benefits:
+ * 1. All functions can be inlined.
+ * 2. nv40 and other pre-DX10 chips without "continue" can be supported
+ * 3. nv30 and other pre-DX10 chips with no control flow at all are better
+ * supported
+ *
+ * Continues are lowered by adding a per-loop "execute flag", initialized to
+ * true, that when cleared inhibits all execution until the end of the loop.
+ *
+ * Breaks are lowered to continues, plus setting a "break flag" that is checked
+ * at the end of the loop, and trigger the unique "break".
+ *
+ * Returns are lowered to breaks/continues, plus adding a "return flag" that
+ * causes loops to break again out of their enclosing loops until all the
+ * loops are exited: then the "execute flag" logic will ignore everything
+ * until the end of the function.
+ *
+ * Note that "continue" and "return" can also be implemented by adding
+ * a dummy loop and using break.
+ * However, this is bad for hardware with limited nesting depth, and
+ * prevents further optimization, and thus is not currently performed.
