+- 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.

+

+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

+  - ir_binop_bit_or

+

+- 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].

-/**
- * \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.

+ * 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.

- * In addition, it is possible to use a switch-statement based on \c

- * types.  For functions that have only slight differences for several object
- * types, this allows writing very straightforward, readable code.

-/**
- * \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.

+/**

+ * \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.

+/**

+ * \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.

- * 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.

+/**

+ * \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.
