- * Sweep-and-update Euclidean distance transform of an
- * image. Positive pixels are treated as object pixels,
- * zero or negative pixels are treated as background.
- * An attempt is made to treat antialiased edges correctly.
- * The input image must have pixels in the range [0,1],
- * and the antialiased image should be a box-filter
- * sampling of the ideal, crisp edge.
- * If the antialias region is more than 1 pixel wide,
- * the result from this transform will be inaccurate.
- *
- * By Stefan Gustavson (stefan.gustavson@gmail.com).
- *
- * Originally written in 1994, based on a verbal
- * description of Per-Erik Danielsson's SSED8 algorithm
- * as presented in the PhD dissertation of Ingemar
- * Ragnemalm. This is Per-Erik Danielsson's scanline
- * scheme from 1979 - I only implemented it in C.
- *
- * Updated in 2004 to treat border pixels correctly,
- * and cleaned up the code to improve readability.
- *
- * Updated in 2009 to handle anti-aliased edges,
- * as published in the article "Anti-aliased Euclidean
- * distance transform" by Stefan Gustavson and Robin Strand,
- * Pattern Recognition Letters 32 (2011) 252–257.
- *
- * Updated in 2011 to avoid a corner case causing an
- * infinite loop for some input data.

- The number of bits that represent a 4x4 texel block is 64 bits if
- <internalformat> is given by ETC1_RGB8_OES.
-
- The data for a block is a number of bytes,
-
- {q0, q1, q2, q3, q4, q5, q6, q7}
-
- where byte q0 is located at the lowest memory address and q7 at
- the highest. The 64 bits specifying the block is then represented
- by the following 64 bit integer:
-
- int64bit = 256*(256*(256*(256*(256*(256*(256*q0+q1)+q2)+q3)+q4)+q5)+q6)+q7;

-Introduction
-============
-
-  The FreeType  Project is distributed in  several archive packages;
-  some of them may contain, in addition to the FreeType font engine,
-  various tools and  contributions which rely on, or  relate to, the
-  FreeType Project.
-
-  This  license applies  to all  files found  in such  packages, and
-  which do not  fall under their own explicit  license.  The license
-  affects  thus  the  FreeType   font  engine,  the  test  programs,
-  documentation and makefiles, at the very least.
-
-  This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
-  (Independent JPEG  Group) licenses, which  all encourage inclusion
-  and  use of  free  software in  commercial  and freeware  products
-  alike.  As a consequence, its main points are that:
-
-    o We don't promise that this software works. However, we will be
-      interested in any kind of bug reports. (`as is' distribution)
-
-    o You can  use this software for whatever you  want, in parts or
-      full form, without having to pay us. (`royalty-free' usage)
-
-    o You may not pretend that  you wrote this software.  If you use
-      it, or  only parts of it,  in a program,  you must acknowledge
-      somewhere  in  your  documentation  that  you  have  used  the
-      FreeType code. (`credits')
-
-  We  specifically  permit  and  encourage  the  inclusion  of  this
-  software, with  or without modifications,  in commercial products.
-  We  disclaim  all warranties  covering  The  FreeType Project  and
-  assume no liability related to The FreeType Project.
-
-
-  Finally,  many  people  asked  us  for  a  preferred  form  for  a
-  credit/disclaimer to use in compliance with this license.  We thus
-  encourage you to use the following text:
-
-   """

-
-
-2016 09
--------
-
-* Metal: Fixed constant precision propagation in some cases.

-2015 08
--------
-
-Changes:
-

-
-
-2015 06
--------
-
-Fixes:
-
-* Fixed some cases of different precision matrix assignments being miscompiled on Metal.
-* Fixed yet more issues with translation of weird loops.
-* Fixed translation of matrix+scalar, matrix-scalar, matrix/scalar operations on Metal.
-
-
-2015 05
--------
-
-Fixes:
-
-* Fixes some cases of highp/mediump sampler sampling resulting in resulting temporaries wrongly being lowp.
-
-
-2015 04
--------
-
-Goodies:
-
-* GLES2: support EXT_draw_instanced / gl_InstanceIDEXT.
-* Support gl_VertexID in GLSL < 1.30 when EXT_gpu_shader4 is used.
-
-Fixes:
-
-* Metal: fixed some bugs with translation of weird loops.
-
-
-2015 02
--------
-
-Tweaks:
-
-* Texture LOD sampling functions on GLES2.0 now produce a wrapper call, that does approximation
-  (mip bias) on devices that don't support GL_EXT_shader_texture_lod.

-
-
-2015 01
--------

-  All uniforms currently will be put into one constant buffer.
-  Pass kGlslTargetMetal target to get Metal.
-* Shader reflection API. See glslopt_shader_get_* functions. Binding indices
-  are only automatically assigned on Metal now; on GL/ES targets the reflection API is only
-  useful to get list of inputs/uniforms, their names and types.
-* Improved dead code elimation: some cases of swizzled/masked assignments where same variable was on both sides
-  were not eliminated if that variable was totally unused later.
-* Merged with upstream Mesa, comes with new optimizations (min/max pruning, tree rebalancing, vector_insert lowering).

-* Fixed vectorization pass in some cases going wrong on texture lookups.
-
-
-2014 06
--------
-
-Goodies:
-
-* Optimization: split vectors with only some used components into scalars.
-
-Fixes:
-
-* Fixed more issues with for-loop printing.
-* Fixed printing of unsigned integer swizzled & constants.
-
-2014 03
--------
-
-Fixes:
-
-* Fixed missing precision qualifier in some ES shaders (mostly due to expansion of ternary ?: check).
-
-2014 02

-
-2014 01
--------
-

-* More OpenGL ES 2.0 conformant printing of complex for-loops (loop inductions printed
-  as += or ++; loop initializers inside loop body).
-
-Fixes:
-
-* Fixed array assignments sometimes appearing in pre-GLSL1.20 versions, especially with
-  complex loops that couldn't be unrolled.
-* Fixed output of textureOffset and texelFetch.
-* Fixed error messages on MRT outputs on GL & GLES3 (now supports 4 MRTs).
-
-2013 12
--------
-
-Goodies:
-
-* Optimized performance; was spending half of the time in stupid string code.
-* Added glslopt_shader_get_stats to get *very* approximate shader complexity stats.
-* Nicer printing of complicated for-loops.
-

-* Merged with upstream Mesa.
-
-Fixes:
-
-* Fixed location qualifiers, ES3.0 version printing, samplerCubeShadow sampling operations.
-
-
-2013 10
--------
-
-Goodies:
-
-* Initial OpenGL ES 3.0 support
-* API to query shader input names; glslopt_shader_get_input_count and glslopt_shader_get_input_name
-
-Changes:
-
-* Xcode project files updated to Xcode 5

-GLSL optimizer
-==============
-
-A C++ library that takes GLSL shaders, does some GPU-independent optimizations on them
-and outputs GLSL or Metal source back. Optimizations are function inlining, dead code removal, copy propagation,
-constant folding, constant propagation, arithmetic optimizations and so on.
-
-Apparently quite a few mobile platforms are pretty bad at optimizing shaders; and
-unfortunately they *also* lack offline shader compilers. So using a GLSL optimizer offline
-before can make the shader run much faster on a platform like that. See performance numbers
-in [this blog post](http://aras-p.info/blog/2010/09/29/glsl-optimizer/).
-
-Even for drivers that have decent shader optimization, GLSL optimizer could be useful to just strip away
-dead code, make shaders smaller and do uniform/input reflection offline.
-
-Almost all actual code is [Mesa 3D's GLSL](http://cgit.freedesktop.org/mesa/mesa/log/)
-compiler; all this library does is spits out optimized GLSL or Metal back, and adds GLES type precision
-handling to the optimizer.
-
-This GLSL optimizer is made for [Unity's](http://unity3d.com/) purposes and is built-in
-starting with Unity 3.0.
-
-GLSL Optimizer is licensed according to the terms of the MIT license.
-
-See [change log here](Changelog.md).
-
-
-Usage
------
-
-Visual Studio 2010 (Windows, x86/x64) and Xcode 5+ (Mac, i386) project files for a static
-library are provided in `projects/vs2010/glsl_optimizer.sln` and `projects/xcode5/glsl_optimizer_lib`
-respectively.
-
-> Note: only the VS and Xcode project files are maintained and should work at any time.
-> There's also a cmake and gyp build system for Linux et al., and some stuff in contrib folder -
-> all that may or might not work.
-
-For Linux you can use cmake. Just type "cmake . && make" in the root directory.
-This will build the optimizer library and some executable binaries.
-
-Interface for the library is `src/glsl/glsl_optimizer.h`. General usage is:
- 
-	ctx = glslopt_initialize(targetVersion);
-	for (lots of shaders) {
-		shader = glslopt_optimize (ctx, shaderType, shaderSource, options);
-		if (glslopt_get_status (shader)) {
-			newSource = glslopt_get_output (shader);
-		} else {
-			errorLog = glslopt_get_log (shader);
-		}
-		glslopt_shader_delete (shader);
-	}
-	glslopt_cleanup (ctx);
-
-
-Tests
------
-
-There's a testing suite for catching regressions, see `tests` folder. In VS, build
-and run `glsl_optimizer_tests` project; in Xcode use `projects/xcode5/glsl_optimizer_tests`
-project. The test executable requires path to the `tests` folder as an argument.
-
-Each test comes as three text files; input, expected IR dump and expected optimized
-GLSL dump. GLES3 tests are also converted into Metal.
-
-If you're making changes to the project and want pull requests accepted easier, I'd
-appreciate if there would be no test suite regressions. If you are implementing a
-feature, it would be cool to add tests to cover it as well!
-
-
-Notes
------
-
-* GLSL versions 1.10 and 1.20 are supported. 1.10 is the default, use #version 120 to specify 
-1.20. Higher GLSL versions might work, but aren't tested now.
-* GLSL ES versions 1.00 and 3.00 are supported.
-
-Status and Future
------------------
-
-**Note**: As of mid-2016, the project is unlikely to have any significant developments. At Unity we are largely moving to a different
-shader compilation pipeline, with glsl-optimizer mostly not used. So from my side there won't be significant work done on it :(
-
-
-Dev Notes
----------
-
-Pulling Mesa upstream:
-
-    git fetch upstream
-    git merge upstream/master
-    sh removeDeletedByUs.sh
-    # inspect files, git rm unneeded ones, fix conflicts etc.
-    # git commit
-    
-Rebuilding flex/bison parsers:
-
-* When .y/.l files are changed, the parsers are *not* rebuilt automatically,
-* Run ./generateParsers.sh to do that. You'll need bison & flex (on Mac, do "Install Command Line Tools" from Xcode)
-* I use bison 2.3 and flex 2.5.35 (in OS X 10.8/10.9)

-Welcome to Mesa's GLSL compiler.  A brief overview of how things flow:
-
-1) lex and yacc-based preprocessor takes the incoming shader string
-and produces a new string containing the preprocessed shader.  This
-takes care of things like #if, #ifdef, #define, and preprocessor macro
-invocations.  Note that #version, #extension, and some others are
-passed straight through.  See glcpp/*
-
-2) lex and yacc-based parser takes the preprocessed string and
-generates the AST (abstract syntax tree).  Almost no checking is
-performed in this stage.  See glsl_lexer.lpp and glsl_parser.ypp.

-3) The AST is converted to "HIR".  This is the intermediate
-representation of the compiler.  Constructors are generated, function
-calls are resolved to particular function signatures, and all the
-semantic checking is performed.  See ast_*.cpp for the conversion, and
-ir.h for the IR structures.
-
-4) The driver (Mesa, or main.cpp for the standalone binary) performs
-optimizations.  These include copy propagation, dead code elimination,
-constant folding, and others.  Generally the driver will call
-optimizations in a loop, as each may open up opportunities for other
-optimizations to do additional work.  See most files called ir_*.cpp
-
-5) linking is performed.  This does checking to ensure that the
-outputs of the vertex shader match the inputs of the fragment shader,
-and assigns locations to uniforms, attributes, and varyings.  See
-linker.cpp.
-
-6) The driver may perform additional optimization at this point, as
-for example dead code elimination previously couldn't remove functions
-or global variable usage when we didn't know what other code would be
-linked in.
-
-7) The driver performs code generation out of the IR, taking a linked
-shader program and producing a compiled program for each stage.  See
-ir_to_mesa.cpp for Mesa IR code generation.
-
-FAQ:
-
-Q: What is HIR versus IR versus LIR?
-
-A: The idea behind the naming was that ast_to_hir would produce a
-high-level IR ("HIR"), with things like matrix operations, structure
-assignments, etc., present.  A series of lowering passes would occur
-that do things like break matrix multiplication into a series of dot
-products/MADs, make structure assignment be a series of assignment of
-components, flatten if statements into conditional moves, and such,
-producing a low level IR ("LIR").
-
-However, it now appears that each driver will have different
-requirements from a LIR.  A 915-generation chipset wants all functions
-inlined, all loops unrolled, all ifs flattened, no variable array
-accesses, and matrix multiplication broken down.  The Mesa IR backend
-for swrast would like matrices and structure assignment broken down,
-but it can support function calls and dynamic branching.  A 965 vertex
-shader IR backend could potentially even handle some matrix operations
-without breaking them down, but the 965 fragment shader IR backend
-would want to break to have (almost) all operations down channel-wise
-and perform optimization on that.  As a result, there's no single
-low-level IR that will make everyone happy.  So that usage has fallen
-out of favor, and each driver will perform a series of lowering passes
-to take the HIR down to whatever restrictions it wants to impose
-before doing codegen.
-
-Q: How is the IR structured?
-
-A: The best way to get started seeing it would be to run the
-standalone compiler against a shader:
-
-./glsl_compiler --dump-lir \
-	~/src/piglit/tests/shaders/glsl-orangebook-ch06-bump.frag
-
-So for example one of the ir_instructions in main() contains:
-
-(assign (constant bool (1)) (var_ref litColor)  (expression vec3 * (var_ref Surf
-aceColor) (var_ref __retval) ) )
-
-Or more visually:
-                     (assign)
-                 /       |        \
-        (var_ref)  (expression *)  (constant bool 1)
-         /          /           \
-(litColor)      (var_ref)    (var_ref)
-                  /                  \
-           (SurfaceColor)          (__retval)
-
-which came from:
-
-litColor = SurfaceColor * max(dot(normDelta, LightDir), 0.0);
-
-(the max call is not represented in this expression tree, as it was a
-function call that got inlined but not brought into this expression
-tree)
-
-Each of those nodes is a subclass of ir_instruction.  A particular
-ir_instruction instance may only appear once in the whole IR tree with
-the exception of ir_variables, which appear once as variable
-declarations:
-
-(declare () vec3 normDelta)
-
-and multiple times as the targets of variable dereferences:
-...
-(assign (constant bool (1)) (var_ref __retval) (expression float dot
- (var_ref normDelta) (var_ref LightDir) ) )
-...
-(assign (constant bool (1)) (var_ref __retval) (expression vec3 -
- (var_ref LightDir) (expression vec3 * (constant float (2.000000))
- (expression vec3 * (expression float dot (var_ref normDelta) (var_ref
- LightDir) ) (var_ref normDelta) ) ) ) )
-...
-
-Each node has a type.  Expressions may involve several different types:
-(declare (uniform ) mat4 gl_ModelViewMatrix)
-((assign (constant bool (1)) (var_ref constructor_tmp) (expression
- vec4 * (var_ref gl_ModelViewMatrix) (var_ref gl_Vertex) ) )
-
-An expression tree can be arbitrarily deep, and the compiler tries to
-keep them structured like that so that things like algebraic
-optimizations ((color * 1.0 == color) and ((mat1 * mat2) * vec == mat1
-* (mat2 * vec))) or recognizing operation patterns for code generation
-(vec1 * vec2 + vec3 == mad(vec1, vec2, vec3)) are easier.  This comes
-at the expense of additional trickery in implementing some
-optimizations like CSE where one must navigate an expression tree.
-
-Q: Why no SSA representation?
-
-A: Converting an IR tree to SSA form makes dead code elmimination,
-common subexpression elimination, and many other optimizations much
-easier.  However, in our primarily vector-based language, there's some
-major questions as to how it would work.  Do we do SSA on the scalar
-or vector level?  If we do it at the vector level, we're going to end
-up with many different versions of the variable when encountering code
-like:
-
-(assign (constant bool (1)) (swiz x (var_ref __retval) ) (var_ref a) ) 
-(assign (constant bool (1)) (swiz y (var_ref __retval) ) (var_ref b) ) 
-(assign (constant bool (1)) (swiz z (var_ref __retval) ) (var_ref c) ) 
-
-If every masked update of a component relies on the previous value of
-the variable, then we're probably going to be quite limited in our
-dead code elimination wins, and recognizing common expressions may
-just not happen.  On the other hand, if we operate channel-wise, then
-we'll be prone to optimizing the operation on one of the channels at
-the expense of making its instruction flow different from the other
-channels, and a vector-based GPU would end up with worse code than if
-we didn't optimize operations on that channel!
-
-Once again, it appears that our optimization requirements are driven
-significantly by the target architecture.  For now, targeting the Mesa
-IR backend, SSA does not appear to be that important to producing
-excellent code, but we do expect to do some SSA-based optimizations
-for the 965 fragment shader backend when that is developed.
-
-Q: How should I expand instructions that take multiple backend instructions?
-
-Sometimes you'll have to do the expansion in your code generation --
-see, for example, ir_to_mesa.cpp's handling of ir_unop_sqrt.  However,
-in many cases you'll want to do a pass over the IR to convert
-non-native instructions to a series of native instructions.  For
-example, for the Mesa backend we have ir_div_to_mul_rcp.cpp because
-Mesa IR (and many hardware backends) only have a reciprocal
-instruction, not a divide.  Implementing non-native instructions this
-way gives the chance for constant folding to occur, so (a / 2.0)
-becomes (a * 0.5) after codegen instead of (a * (1.0 / 2.0))
-
-Q: How shoud I handle my special hardware instructions with respect to IR?
-
-Our current theory is that if multiple targets have an instruction for
-some operation, then we should probably be able to represent that in
-the IR.  Generally this is in the form of an ir_{bin,un}op expression
-type.  For example, we initially implemented fract() using (a -
-floor(a)), but both 945 and 965 have instructions to give that result,
-and it would also simplify the implementation of mod(), so
-ir_unop_fract was added.  The following areas need updating to add a
-new expression type:
-
-ir.h (new enum)
-ir.cpp:operator_strs (used for ir_reader)
-ir_constant_expression.cpp (you probably want to be able to constant fold)
-ir_validate.cpp (check users have the right types)
-
-You may also need to update the backends if they will see the new expr type:
-
-../mesa/shaders/ir_to_mesa.cpp
-
-You can then use the new expression from builtins (if all backends
-would rather see it), or scan the IR and convert to use your new
-expression type (see ir_mod_to_fract, for example).
-
-Q: How is memory management handled in the compiler?
-
-The hierarchical memory allocator "talloc" developed for the Samba
-project is used, so that things like optimization passes don't have to
-worry about their garbage collection so much.  It has a few nice
-features, including low performance overhead and good debugging
-support that's trivially available.
-
-Generally, each stage of the compile creates a talloc context and
-allocates its memory out of that or children of it.  At the end of the
-stage, the pieces still live are stolen to a new context and the old
-one freed, or the whole context is kept for use by the next stage.
-
-For IR transformations, a temporary context is used, then at the end
-of all transformations, reparent_ir reparents all live nodes under the
-shader's IR list, and the old context full of dead nodes is freed.
-When developing a single IR transformation pass, this means that you
-want to allocate instruction nodes out of the temporary context, so if
-it becomes dead it doesn't live on as the child of a live node.  At
-the moment, optimization passes aren't passed that temporary context,
-so they find it by calling talloc_parent() on a nearby IR node.  The
-talloc_parent() call is expensive, so many passes will cache the
-result of the first talloc_parent().  Cleaning up all the optimization
-passes to take a context argument and not call talloc_parent() is left
-as an exercise.
-
-Q: What is the file naming convention in this directory?
-
-Initially, there really wasn't one.  We have since adopted one:
-
- - Files that implement code lowering passes should be named lower_*
-   (e.g., lower_noise.cpp).
- - Files that implement optimization passes should be named opt_*.
- - Files that implement a class that is used throught the code should
-   take the name of that class (e.g., ir_hierarchical_visitor.cpp).
- - Files that contain code not fitting in one of the previous
-   categories should have a sensible name (e.g., glsl_parser.ypp).

-       * front-end for using this construct.  This allows useful things such

-       * loop in unrolled, the code should compile correctly.  Instead, emit a
-       * warning.
-       *
-       * In GLSL 4.00 / ARB_gpu_shader5, this requirement is relaxed again to allow
-       * indexing with dynamically uniform expressions. Note that these are not
-       * required to be uniforms or expressions based on them, but merely that the
-       * values must not diverge between shader invocations run together. If the

-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.1.30.10.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 a draft of
-the C99 standard as available from:
-
-http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf
-
-Any downstream compiler accepting output from glcpp should be prepared
-to encounter and deal with the following preprocessor macros:
-
-	#line
-	#pragma
-	#extension
-
-All other macros will be handled according to the GLSL specification
-and will not appear in the output.
-
-Known limitations
------------------
-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).

-	 *	   #else of an #if 0, etc.).
-	 *
-	 *	3. The lexing_directive bit overrides the skip stack. This bit
-	 *	   is set when we are actively lexing the expression for a
-	 *	   pre-processor condition, (such as #if, #elif, or #else). In
-	 *	   this case, even if otherwise skipping, we need to emit the
-	 *	   tokens for this condition so that the parser can evaluate
-	 *	   the expression. (For, #else, there's no expression, but we
