-# - Sign up
-# - Add a new project
-# - Select Git and fill in the Git clone URL
-# - Setup a Git hook as explained in
-#   https://github.com/appveyor/webhooks#installing-git-hook
-# - Check 'Settings > General > Skip branches without appveyor.yml'
-# - Check 'Settings > General > Rolling builds'
-# - Setup the global or project notifications to your liking

-Mesa 10.6.6 is a bug fix release which fixes bugs found since the 10.6.5 release.

-<p>
-Mesa 10.6.6 implements the OpenGL 3.3 API, but the version reported by
-glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
-glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 3.3.  OpenGL
-3.3 is <strong>only</strong> available if requested at context creation
-because compatibility contexts are not supported.

-
-<p>
-Mesa 11.0.5 is a bug fix release which fixes bugs found since the 11.0.4 release.
-</p>
-<p>
-Mesa 11.0.5 implements the OpenGL 4.1 API, but the version reported by
-glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
-glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
-4.1 is <strong>only</strong> available if requested at context creation
-because compatibility contexts are not supported.

-<h1>Mesa 11.0.8 Release Notes / December 9, 2015</h1>
-
-<p>
-Mesa 11.0.8 is a bug fix release which fixes bugs found since the 11.0.7 release.
-</p>
-<p>
-Mesa 11.0.8 implements the OpenGL 4.1 API, but the version reported by
-glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
-glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
-4.1 is <strong>only</strong> available if requested at context creation
-because compatibility contexts are not supported.

-<h1>Mesa 11.1.1 Release Notes / January 13, 2016</h1>
-
-<p>
-Mesa 11.1.1 is a bug fix release which fixes bugs found since the 11.1.0 release.
-</p>
-<p>
-Mesa 11.1.1 implements the OpenGL 4.1 API, but the version reported by
-glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
-glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
-4.1 is <strong>only</strong> available if requested at context creation
-because compatibility contexts are not supported.
-</p>

-<h1>Mesa 11.1.2 Release Notes / February 10, 2016</h1>
-
-<p>
-Mesa 11.1.2 is a bug fix release which fixes bugs found since the 11.1.1 release.
-</p>
-<p>
-Mesa 11.1.2 implements the OpenGL 4.1 API, but the version reported by
-glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
-glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
-4.1 is <strong>only</strong> available if requested at context creation
-because compatibility contexts are not supported.

-
-<p>
-Mesa 11.2.1 is a bug fix release which fixes bugs found since the 11.2.0 release.
-</p>
-<p>
-Mesa 11.2.1 implements the OpenGL 4.1 API, but the version reported by
-glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
-glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
-4.1 is <strong>only</strong> available if requested at context creation
-because compatibility contexts are not supported.

-    Specification
-
-Overview
-
-    Multisampled antialiasing has become a common method for improving the
-    quality of rendered images.  Multisampling differs from supersampling in
-    that the color of a primitive that covers all or part of a pixel is
-    resolved once, regardless of the number of samples covered.  If a large
-    polygon is rendered, the colors of all samples in each interior pixel will
-    be the same.  This suggests a simple compression scheme that can reduce
-    the necessary memory bandwidth requirements.  In one such scheme, each
-    sample is stored in a separate slice of the multisample surface.  An
-    additional multisample control surface (MCS) contains a mapping from pixel
-    samples to slices.
-
-    If all the values stored in the MCS for a particular pixel are the same,
-    then all the samples have the same value.  Applications can take advantage
-    of this information to reduce the bandwidth of reading multisample
-    textures.  A custom multisample resolve filter could optimize resolving
-    pixels where every sample is identical by reading the color once.
-
-    color = texelFetch(sampler, coordinate, 0);
-    if (!textureSamplesIdenticalEXT(sampler, coordinate)) {
-        for (int i = 1; i < MAX_SAMPLES; i++) {
-            vec4 c = texelFetch(sampler, coordinate, i);
-
-            //... accumulate c into color
-
-        }
-    }

-
-    Including the following line in a shader can be used to control the
-    language features described in this extension:
-
-        #extension GL_EXT_shader_samples_identical
-
-    A new preprocessor #define is added to the OpenGL Shading Language:
-
-        #define GL_EXT_shader_samples_identical
-
-    Add to the table in section 8.7 "Texture Lookup Functions"
-
-    Syntax:
-
-        bool textureSamplesIdenticalEXT(gsampler2DMS sampler, ivec2 coord)
-
-        bool textureSamplesIdenticalEXT(gsampler2DMSArray sampler,
-                                        ivec3 coord)
-
-    Description:
-
-        Returns true if it can be determined that all samples within the texel
-        of the multisample texture bound to <sampler> at <coord> contain the
-        same values or false if this cannot be determined."

-
-Issues
-
-    1) What should the new functions be called?
-
-    RESOLVED: textureSamplesIdenticalEXT.  Initially
-    textureAllSamplesIdenticalEXT was considered, but
-    textureSamplesIdenticalEXT is more similar to the existing textureSamples
-    function.
-
-    2) It seems like applications could implement additional optimization if
-       they were provided with raw MCS data.  Should this extension also
-       provide that data?
-
-    There are a number of challenges in providing raw MCS data.  The biggest
-    problem being that the amount of MCS data depends on the number of
-    samples, and that is not known at compile time.  Additionally, without new
-    texelFetch functions, applications would have difficulty utilizing the
-    information.
-
-    Another option is to have a function that returns an array of tuples of
-    sample number and count.  This also has difficulties with the maximum
-    array size not being known at compile time.
-
-    RESOLVED: Do not expose raw MCS data in this extension.
-
-    3) Should this extension also extend SPIR-V?
-
-    RESOLVED: Yes, but this has not yet been written.
-
-    4) Is it possible for textureSamplesIdenticalEXT to report false negatives?
-
-    RESOLVED: Yes.  It is possible that the underlying hardware may not detect
-    that separate writes of the same color to different samples of a pixel are
-    the same.  The shader function is at the whim of the underlying hardware
-    implementation.  It is also possible that a compressed multisample surface
-    is not used.  In that case the function will likely always return false.

-# We write our own rules for yacc and lex below. We'd rather use automake,
-# but automake makes it especially difficult for a number of reasons:
-#
-#  * < automake-1.12 generates .h files from .yy and .ypp files, but
-#    >=automake-1.12 generates .hh and .hpp files respectively. There's no
-#    good way of making a project that uses C++ yacc files compatible with
-#    both versions of automake. Strong work automake developers.
-#
-#  * Since we're generating code from .l/.y files in a subdirectory (glcpp/)
-#    we'd like the resulting generated code to also go in glcpp/ for purposes
-#    of distribution. Automake gives no way to do this.
-#
-#  * Since we're building multiple yacc parsers into one library (and via one
-#    Makefile) we have to use per-target YFLAGS. Using per-target YFLAGS causes
-#    automake to name the resulting generated code as <library-name>_filename.c.
-#    Frankly, that's ugly and we don't want a libglcpp_glcpp_parser.h file.
-
-# In order to make build output print "LEX" and "YACC", we reproduce the
-# automake variables below.

-/**
- * \name Control flow modification
- *
- * These functions modify the control flow tree while keeping the control flow
- * graph up-to-date. The invariants respected are:
- * 1. Each then statement, else statement, or loop body must have at least one
- *    control flow node.
- * 2. Each if-statement and loop must have one basic block before it and one
- *    after.
- * 3. Two basic blocks cannot be directly next to each other.
- * 4. If a basic block has a jump instruction, there must be only one and it
- *    must be at the end of the block.
- * 5. The CFG must always be connected - this means that we must insert a fake
- *    CFG edge for loops with no break statement.
- *
- * The purpose of the second one is so that we have places to insert code during
- * GCM, as well as eliminating the possibility of critical edges.

-/** Control flow motion.
- *
- * These functions let you take a part of a control flow list (basically
- * equivalent to a series of statement in GLSL) and "extract" it from the IR,
- * so that it's a free-floating piece of IR that can be either re-inserted
- * somewhere else or deleted entirely. A few notes on using it:
- *
- * 1. Phi nodes are considered attached to the piece of control flow that
- *    their sources come from. There are three places where phi nodes can
- *    occur, which are the three places where a block can have multiple
- *    predecessors:
- *
- *    1) After an if statement, if neither branch ends in a jump.
- *    2) After a loop, if there are multiple break's.
- *    3) At the beginning of a loop.
- *
- *    For #1, the phi node is considered to be part of the if, and for #2 and
- *    #3 the phi node is considered to be part of the loop. This allows us to
- *    keep phi's intact, but it means that phi nodes cannot be separated from
- *    the control flow they come from. For example, extracting an if without
- *    extracting all the phi nodes after it is not allowed, and neither is
- *    extracting only some of the phi nodes at the beginning of a block. It
- *    also means that extracting from the beginning of a basic block actually
- *    means extracting from the first non-phi instruction, since there's no
- *    situation where extracting phi nodes without extracting what comes
- *    before them makes any sense.
- *
- * 2. Phi node sources are guaranteed to remain valid, meaning that they still
- *    correspond one-to-one with the predecessors of the basic block they're
- *    part of. In addition, the original sources will be preserved unless they
- *    correspond to a break or continue that was deleted. However, no attempt
- *    is made to ensure that SSA form is maintained. In particular, it is
- *    *not* guaranteed that definitions of SSA values will dominate all their
- *    uses after all is said and done. Either the caller must ensure that this
- *    is the case, or it must insert extra phi nodes to restore SSA.
- *
- * 3. It is invalid to move a piece of IR with a break/continue outside of the
- *    loop it references. Doing this will result in invalid
- *    successors/predecessors and phi node sources.
- *
- * 4. It is invalid to move a piece of IR from one function implementation to
- *    another.
- *
- * 5. Extracting a control flow list will leave lots of dangling references to
- *    and from other pieces of the IR. It also leaves things in a not 100%
- *    consistent state. This means that some things (e.g. inserting
- *    instructions) might not work reliably on the extracted control flow. It
- *    also means that extracting control flow without re-inserting it or
- *    deleting it is a Bad Thing (tm).

- * Which should correspond one-to-one with the nir_intrinsic_info structure. It
- * is included in both ir.h to create the nir_intrinsic enum (with members of
- * the form nir_intrinsic_(name)) and and in opcodes.c to create
- * nir_intrinsic_infos, which is a const array of nir_intrinsic_info structures

-/**
- * \file nir_lower_gs_intrinsics.c
- *
- * Geometry Shaders can call EmitVertex()/EmitStreamVertex() to output an
- * arbitrary number of vertices.  However, the shader must declare the maximum
- * number of vertices that it will ever output - further attempts to emit
- * vertices result in undefined behavior according to the GLSL specification.
- *
- * Drivers might use this maximum number of vertices to allocate enough space
- * to hold the geometry shader's output.  Some drivers (such as i965) need to
- * implement "safety checks" which ensure that the shader hasn't emitted too
- * many vertices, to avoid overflowing that space and trashing other memory.
- *
- * The count of emitted vertices can also be useful in buffer offset
- * calculations, so drivers know where to write the GS output.
- *
- * However, for simple geometry shaders that emit a statically determinable
- * number of vertices, this extra bookkeeping is unnecessary and inefficient.
- * By tracking the vertex count in NIR, we allow constant folding/propagation
- * and dead control flow optimizations to eliminate most of it where possible.
- *
- * This pass introduces a new global variable which stores the current vertex
- * count (initialized to 0), and converts emit_vertex/end_primitive intrinsics
- * to their *_with_counter variants.  emit_vertex is also wrapped in a safety
- * check to avoid buffer overflows.  Finally, it adds a set_vertex_count
- * intrinsic at the end of the program, informing the driver of the final
- * vertex count.

- * This file implements an optimization that deletes statically
- * unreachable/dead code. In NIR, one way this can happen if if an if
- * statement has a constant condition:
- *
- * if (true) {
- *    ...
- * }
- *
- * We delete the if statement and paste the contents of the always-executed
- * branch into the surrounding control flow, possibly removing more code if
- * the branch had a jump at the end.
- *
- * Another way is that control flow can end in a jump so that code after it
- * never gets executed. In particular, this can happen after optimizing
- * something like:
- *
- * if (true) {
- *    ...
- *    break;
- * }
- * ...
- *
- * We also consider the case where both branches of an if end in a jump, e.g.:
- *
- * if (...) {
- *    break;
- * } else {
- *    continue;
- * }
- * ...
- *
- * Finally, we also handle removing useless loops, i.e. loops with no side
- * effects and without any definitions that are used elsewhere. This case is a
- * little different from the first two in that the code is actually run (it
- * just never does anything), but there are similar issues with needing to
- * be careful with restarting after deleting the cf_node (see dead_cf_list())
