+VERSION
+--------------------------------------------------------------------------------
+spirv-remap 0.97
+
+INTRO:
+--------------------------------------------------------------------------------
+spirv-remap is a utility to improve compression of SPIR-V binary files via
+entropy reduction, plus optional stripping of debug information and
+load/store optimization.  It transforms SPIR-V to SPIR-V, remapping IDs.  The
+resulting modules have an increased ID range (IDs are not as tightly packed
+around zero), but will compress better when multiple modules are compressed
+together, since compressor's dictionary can find better cross module
+commonality.
+
+Remapping is accomplished via canonicalization.  Thus, modules can be
+compressed one at a time with no loss of quality relative to operating on
+many modules at once.  The command line tool operates on multiple modules
+only in the trivial repetition sense, for ease of use.  The remapper API
+only accepts a single module at a time.
+
+There are two modes of use: command line, and a C++11 API.  Both are
+described below.
+
+spirv-remap is currently in an alpha state.  Although there are no known
+remapping defects, it has only been exercised on one real world game shader
+workload.
+
+
+FEEDBACK
+--------------------------------------------------------------------------------
+Report defects, enhancements requests, code improvements, etc to:
+   spvremapper@lunarg.com
+
+
+COMMAND LINE USAGE:
+--------------------------------------------------------------------------------
+Examples are given with a verbosity of one (-v), but more verbosity can be
+had via -vv, -vvv, etc, or an integer parameter to --verbose, such as
+"--verbose 4".  With no verbosity, the command is silent and returns 0 on
+success, and a positive integer error on failure.
+
+Pre-built binaries for several OSs are available.  Examples presented are
+for Linux.  Command line arguments can be provided in any order.
+
+1. Basic ID remapping
+
+Perform ID remapping on all shaders in "*.spv", writing new files with
+the same basenames to /tmp/out_dir.
+
+  spirv-remap -v --map all --input *.spv --output /tmp/out_dir
+
+2. Perform all possible size reductions
+
+  spirv-remap-linux-64 -v --do-everything --input *.spv --output /tmp/out_dir
+
+Note that --do-everything is a synonym for:
+
+  --map all --dce all --opt all --strip all
+
+API USAGE:
+--------------------------------------------------------------------------------
+
+The public interface to the remapper is defined in SPIRV/SPVRemapper.h as follows:
+
+namespace spv {
+
+class spirvbin_t
+{
+public:
+   enum Options { ... };
+   spirvbin_t(int verbose = 0);  // construct
+
+   // remap an existing binary in memory
+   void remap(std::vector<std::uint32_t>& spv, std::uint32_t opts = DO_EVERYTHING);
+
+   // Type for error/log handler functions
+   typedef std::function<void(const std::string&)> errorfn_t;
+   typedef std::function<void(const std::string&)> logfn_t;
+
+   // Register error/log handling functions (can be c/c++ fn, lambda fn, or functor)
+   static void registerErrorHandler(errorfn_t handler) { errorHandler = handler; }
+   static void registerLogHandler(logfn_t handler)     { logHandler   = handler; }
+};
+
+} // namespace spv
+
+The class definition is in SPVRemapper.cpp.
+
+remap() accepts an std::vector of SPIR-V words, modifies them per the
+request given in 'opts', and leaves the 'spv' container with the result.
+It is safe to instantiate one spirvbin_t per thread and process a different
+SPIR-V in each.
+
+The "opts" parameter to remap() accepts a bit mask of desired remapping
+options.  See REMAPPING AND OPTIMIZATION OPTIONS.
+
+On error, the function supplied to registerErrorHandler() will be invoked.
+This can be a standard C/C++ function, a lambda function, or a functor.
+The default handler simply calls exit(5); The error handler is a static
+member, so need only be set up once, not once per spirvbin_t instance.
+
+Log messages are supplied to registerLogHandler().  By default, log
+messages are eaten silently.  The log handler is also a static member.
+
+BUILD DEPENDENCIES:

+ 1. C++11 compatible compiler
+ 2. cmake
+ 3. glslang
+
+
+BUILDING
+--------------------------------------------------------------------------------
+The standalone remapper is built along side glslangValidator through its
+normal build process.
+
+
+REMAPPING AND OPTIMIZATION OPTIONS
+--------------------------------------------------------------------------------
+API:
+   These are bits defined under spv::spirvbin_t::, and can be
+   bitwise or-ed together as desired.

+   DCE_VARS       = remove dead variables
+   DCE_TYPES      = remove dead types
+   OPT_LOADSTORE  = optimize unneeded load/stores

+regarding the feature level of glslang.

+glslang
+=======
+
+[![Build Status](https://travis-ci.org/KhronosGroup/glslang.svg?branch=master)](https://travis-ci.org/KhronosGroup/glslang)
+[![Build status](https://ci.appveyor.com/api/projects/status/q6fi9cb0qnhkla68/branch/master?svg=true)](https://ci.appveyor.com/project/Khronoswebmaster/glslang/branch/master)
+
+An OpenGL and OpenGL ES shader front end and validator.
+
+There are several components:
+
+1. A GLSL/ESSL front-end for reference validation and translation of GLSL/ESSL into an AST.
+
+2. An HLSL front-end for translation of a broad generic HLL into the AST. See [issue 362](https://github.com/KhronosGroup/glslang/issues/362) and [issue 701](https://github.com/KhronosGroup/glslang/issues/701) for current status.
+
+3. A SPIR-V back end for translating the AST to SPIR-V.
+
+4. A standalone wrapper, `glslangValidator`, that can be used as a command-line tool for the above.
+
+How to add a feature protected by a version/extension/stage/profile:  See the
+comment in `glslang/MachineIndependent/Versions.cpp`.
+
+Tasks waiting to be done are documented as GitHub issues.
+
+Execution of Standalone Wrapper
+-------------------------------
+
+To use the standalone binary form, execute `glslangValidator`, and it will print
+a usage statement.  Basic operation is to give it a file containing a shader,
+and it will print out warnings/errors and optionally an AST.
+
+The applied stage-specific rules are based on the file extension:
+* `.vert` for a vertex shader
+* `.tesc` for a tessellation control shader
+* `.tese` for a tessellation evaluation shader
+* `.geom` for a geometry shader
+* `.frag` for a fragment shader
+* `.comp` for a compute shader
+
+There is also a non-shader extension
+* `.conf` for a configuration file of limits, see usage statement for example
+
+Building
+--------
+
+### Dependencies
+
+* [CMake][cmake]: for generating compilation targets.
+* [bison][bison]: _optional_, but needed when changing the grammar (glslang.y).
+* [googletest][googletest]: _optional_, but should use if making any changes to glslang.
+
+### Build steps
+
+#### 1) Check-Out this project 
+
+```bash
+cd <parent of where you want glslang to be>
+# If using SSH
+git clone git@github.com:KhronosGroup/glslang.git
+# Or if using HTTPS
+git clone https://github.com/KhronosGroup/glslang.git
+```
+
+#### 2) Check-Out External Projects
+
+```bash
+cd <the directory glslang was cloned to, "External" will be a subdirectory>
+git clone https://github.com/google/googletest.git External/googletest
+```
+
+#### 3) Configure
+
+Assume the source directory is `$SOURCE_DIR` and
+the build directory is `$BUILD_DIR`:
+
+For building on Linux (assuming using the Ninja generator):
+
+```bash
+cd $BUILD_DIR
+
+cmake -GNinja -DCMAKE_BUILD_TYPE={Debug|Release|RelWithDebInfo} \
+      -DCMAKE_INSTALL_PREFIX=`pwd`/install $SOURCE_DIR
+```
+
+For building on Windows:
+
+```bash
+cmake $SOURCE_DIR -DCMAKE_INSTALL_PREFIX=`pwd`/install
+# The CMAKE_INSTALL_PREFIX part is for testing (explained later).
+```
+
+The CMake GUI also works for Windows (version 3.4.1 tested).
+
+#### 4) Build and Install
+
+```bash
+# for Linux:
+ninja install
+
+# for Windows:
+cmake --build . --config {Release|Debug|MinSizeRel|RelWithDebInfo} \
+      --target install
+```
+
+If using MSVC, after running CMake to configure, use the
+Configuration Manager to check the `INSTALL` project.
+
+### If you need to change the GLSL grammar
+
+The grammar in `glslang/MachineIndependent/glslang.y` has to be recompiled with
+bison if it changes, the output files are committed to the repo to avoid every
+developer needing to have bison configured to compile the project when grammar
+changes are quite infrequent. For windows you can get binaries from
+[GnuWin32][bison-gnu-win32].
+
+The command to rebuild is:
+
+```bash
+bison --defines=MachineIndependent/glslang_tab.cpp.h
+      -t MachineIndependent/glslang.y
+      -o MachineIndependent/glslang_tab.cpp
+```
+
+The above command is also available in the bash script at
+`glslang/updateGrammar`.
+
+Testing
+-------
+
+Right now, there are two test harnesses existing in glslang: one is [Google
+Test](gtests/), one is the [`runtests` script](Test/runtests). The former
+runs unit tests and single-shader single-threaded integration tests, while
+the latter runs multiple-shader linking tests and multi-threaded tests.
+
+### Running tests
+
+The [`runtests` script](Test/runtests) requires compiled binaries to be
+installed into `$BUILD_DIR/install`. Please make sure you have supplied the
+correct configuration to CMake (using `-DCMAKE_INSTALL_PREFIX`) when building;
+otherwise, you may want to modify the path in the `runtests` script.
+
+Running Google Test-backed tests:
+
+```bash
+cd $BUILD_DIR
+
+# for Linux:
+ctest
+
+# for Windows:
+ctest -C {Debug|Release|RelWithDebInfo|MinSizeRel}
+
+# or, run the test binary directly
+# (which gives more fine-grained control like filtering):
+<dir-to-glslangtests-in-build-dir>/glslangtests
+```
+
+Running `runtests` script-backed tests:
+
+```bash
+cd $SOURCE_DIR/Test && ./runtests
+```
+
+### Contributing tests
+
+Test results should always be included with a pull request that modifies
+functionality.
+
+If you are writing unit tests, please use the Google Test framework and
+place the tests under the `gtests/` directory.
+
+Integration tests are placed in the `Test/` directory. It contains test input
+and a subdirectory `baseResults/` that contains the expected results of the
+tests.  Both the tests and `baseResults/` are under source-code control.
+
+Google Test runs those integration tests by reading the test input, compiling
+them, and then compare against the expected results in `baseResults/`. The
+integration tests to run via Google Test is registered in various
+`gtests/*.FromFile.cpp` source files. `glslangtests` provides a command-line
+option `--update-mode`, which, if supplied, will overwrite the golden files
+under the `baseResults/` directory with real output from that invocation.
+For more information, please check `gtests/` directory's
+[README](gtests/README.md).
+
+For the `runtests` script, it will generate current results in the
+`localResults/` directory and `diff` them against the `baseResults/`.
+When you want to update the tracked test results, they need to be
+copied from `localResults/` to `baseResults/`.  This can be done by
+the `bump` shell script.
+
+You can add your own private list of tests, not tracked publicly, by using
+`localtestlist` to list non-tracked tests.  This is automatically read
+by `runtests` and included in the `diff` and `bump` process.
+
+Programmatic Interfaces
+-----------------------
+
+Another piece of software can programmatically translate shaders to an AST
+using one of two different interfaces:
+* A new C++ class-oriented interface, or
+* The original C functional interface
+
+The `main()` in `StandAlone/StandAlone.cpp` shows examples using both styles.
+
+### C++ Class Interface (new, preferred)
+
+This interface is in roughly the last 1/3 of `ShaderLang.h`.  It is in the
+glslang namespace and contains the following.
+
+```cxx
+const char* GetEsslVersionString();
+const char* GetGlslVersionString();
+bool InitializeProcess();
+void FinalizeProcess();
+
+class TShader
+    bool parse(...);
+    void setStrings(...);
+    const char* getInfoLog();
+
+class TProgram
+    void addShader(...);
+    bool link(...);
+    const char* getInfoLog();
+    Reflection queries
+```
+
+See `ShaderLang.h` and the usage of it in `StandAlone/StandAlone.cpp` for more
+details.
+
+### C Functional Interface (orignal)
+
+This interface is in roughly the first 2/3 of `ShaderLang.h`, and referred to
+as the `Sh*()` interface, as all the entry points start `Sh`.
+
+The `Sh*()` interface takes a "compiler" call-back object, which it calls after
+building call back that is passed the AST and can then execute a backend on it.
+
+The following is a simplified resulting run-time call stack:
+
+```c
+ShCompile(shader, compiler) -> compiler(AST) -> <back end>
+```
+
+In practice, `ShCompile()` takes shader strings, default version, and
+warning/error and other options for controlling compilation.
+
+Basic Internal Operation
+------------------------
+
+* Initial lexical analysis is done by the preprocessor in
+  `MachineIndependent/Preprocessor`, and then refined by a GLSL scanner
+  in `MachineIndependent/Scan.cpp`.  There is currently no use of flex.
+
+* Code is parsed using bison on `MachineIndependent/glslang.y` with the
+  aid of a symbol table and an AST.  The symbol table is not passed on to
+  the back-end; the intermediate representation stands on its own.
+  The tree is built by the grammar productions, many of which are
+  offloaded into `ParseHelper.cpp`, and by `Intermediate.cpp`.
+
+* The intermediate representation is very high-level, and represented
+  as an in-memory tree.   This serves to lose no information from the
+  original program, and to have efficient transfer of the result from
+  parsing to the back-end.  In the AST, constants are propogated and
+  folded, and a very small amount of dead code is eliminated.
+
+  To aid linking and reflection, the last top-level branch in the AST
+  lists all global symbols.
+
+* The primary algorithm of the back-end compiler is to traverse the
+  tree (high-level intermediate representation), and create an internal
+  object code representation.  There is an example of how to do this
+  in `MachineIndependent/intermOut.cpp`.
+
+* Reduction of the tree to a linear byte-code style low-level intermediate
+  representation is likely a good way to generate fully optimized code.
+
+* There is currently some dead old-style linker-type code still lying around.
+
+* Memory pool: parsing uses types derived from C++ `std` types, using a
+  custom allocator that puts them in a memory pool.  This makes allocation
+  of individual container/contents just few cycles and deallocation free.
+  This pool is popped after the AST is made and processed.
+
+  The use is simple: if you are going to call `new`, there are three cases:
+
+  - the object comes from the pool (its base class has the macro
+    `POOL_ALLOCATOR_NEW_DELETE` in it) and you do not have to call `delete`
+
+  - it is a `TString`, in which case call `NewPoolTString()`, which gets
+    it from the pool, and there is no corresponding `delete`
+
+  - the object does not come from the pool, and you have to do normal
+    C++ memory management of what you `new`

+// The SPIR-V spec requires code blocks to appear in an order satisfying the
+// dominator-tree direction (ie, dominator before the dominated).  This is,
+// actually, easy to achieve: any pre-order CFG traversal algorithm will do it.
+// Because such algorithms visit a block only after traversing some path to it
+// from the root, they necessarily visit the block's idom first.
+//
+// But not every graph-traversal algorithm outputs blocks in an order that
+// appears logical to human readers.  The problem is that unrelated branches may
+// be interspersed with each other, and merge blocks may come before some of the
+// branches being merged.
+//
+// A good, human-readable order of blocks may be achieved by performing
+// depth-first search but delaying merge nodes until after all their branches
+// have been visited.  This is implemented below by the inReadableOrder()
+// function.

+// - C++ will have tokens in the "spv" name space, e.g.: spv::SourceLanguageGLSL
+// - C++11 will use enum classes in the spv namespace, e.g.: spv::SourceLanguage::GLSL
