gl4: don't reference two-volumes attributes if not used
The naomi2 vertex shader doesn't set 2-volume attributes (vtx_base1, vtx_offs1 and vtx_uv1) if they aren't used. But the pixel shader always references them even though they aren't actually used. This breaks some gl drivers: "The shader uses varying vtx_uv1, but previous shader does not write to it." Fixes MINIDUMP-93

--------------------------------------------------------------------------------
-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:
-   [email protected]
-
-
-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;

-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.

-## Planned Deprecations/Removals
-
-1. **SPIRV Folder, 1-May, 2020.** Glslang, when installed through CMake,
-will install a `SPIRV` folder into `${CMAKE_INSTALL_INCLUDEDIR}`.
-This `SPIRV` folder is being moved to `glslang/SPIRV`.
-During the transition the `SPIRV` folder will be installed into both locations.
-The old install of `SPIRV/` will be removed as a CMake install target no sooner than May 1, 2020.
-See issue #1964.
-
-2. **Visual Studio 2013, 20-July, 2020.** Keeping code compiling for MS Visual Studio 2013 will no longer be
-a goal as of July 20, 2020, the fifth anniversary of the release of Visual Studio 2015.
-
-# Glslang Components and Status
-
-There are several components:
-
-### Reference Validator and GLSL/ESSL -> AST Front End
-
-An OpenGL GLSL and OpenGL|ES GLSL (ESSL) front-end for reference validation and translation of GLSL/ESSL into an internal abstract syntax tree (AST).
-
-**Status**: Virtually complete, with results carrying similar weight as the specifications.
-
-### HLSL -> AST Front End
-
-An HLSL front-end for translation of an approximation of HLSL to glslang's AST form.
-
-**Status**: Partially complete. Semantics are not reference quality and input is not validated.
-This is in contrast to the [DXC project](https://github.com/Microsoft/DirectXShaderCompiler), which receives a much larger investment and attempts to have definitive/reference-level semantics.
-
-See [issue 362](https://github.com/KhronosGroup/glslang/issues/362) and [issue 701](https://github.com/KhronosGroup/glslang/issues/701) for current status.
-
-### AST -> SPIR-V Back End
-
-Translates glslang's AST to the Khronos-specified SPIR-V intermediate language.
-
-**Status**: Virtually complete.
-
-### Reflector
-
-An API for getting reflection information from the AST, reflection types/variables/etc. from the HLL source (not the SPIR-V).
-
-**Status**: There is a large amount of functionality present, but no specification/goal to measure completeness against.  It is accurate for the input HLL and AST, but only approximate for what would later be emitted for SPIR-V.
-
-### Standalone Wrapper
-
-`glslangValidator` is command-line tool for accessing the functionality above.
-
-Status: Complete.
-
-Tasks waiting to be done are documented as GitHub issues.
-
-## Other References
-
-Also see the Khronos landing page for glslang as a reference front end:
-
-https://www.khronos.org/opengles/sdk/tools/Reference-Compiler/
-
-The above page, while not kept up to date, includes additional information regarding glslang as a reference validator.
-
-# How to Use Glslang
-
-## 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
-
-Instead of building manually, you can also download the binaries for your
-platform directly from the [master-tot release][master-tot-release] on GitHub.
-Those binaries are automatically uploaded by the buildbots after successful
-testing and they always reflect the current top of the tree of the master
-branch.
-
-### Dependencies
-
-* A C++11 compiler.
-  (For MSVS: 2015 is recommended, 2013 is fully supported/tested, and 2010 support is attempted, but not tested.)
-* [CMake][cmake]: for generating compilation targets.
-* make: _Linux_, ninja is an alternative, if configured.
-* [Python 3.x][python]: for executing SPIRV-Tools scripts. (Optional if not using SPIRV-Tools and the 'External' subdirectory does not exist.)
-* [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
-
-The following steps assume a Bash shell. On Windows, that could be the Git Bash
-shell or some other shell of your choosing.
-
-#### 1) Check-Out this project
-
-```bash
-cd <parent of where you want glslang to be>
-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
-```
-
-If you want to use googletest with Visual Studio 2013, you also need to check out an older version:
-
-```bash
-# to use googletest with Visual Studio 2013
-cd External/googletest
-git checkout 440527a61e1c91188195f7de212c63c77e8f0a45
-cd ../..
-```
-
-If you wish to assure that SPIR-V generated from HLSL is legal for Vulkan,
-wish to invoke -Os to reduce SPIR-V size from HLSL or GLSL, or wish to run the
-integrated test suite, install spirv-tools with this:
-
-```bash
-./update_glslang_sources.py
-```
-
-#### 3) Configure
-
-Assume the source directory is `$SOURCE_DIR` and the build directory is
-`$BUILD_DIR`. First ensure the build directory exists, then navigate to it:
-
-```bash
-mkdir -p $BUILD_DIR
-cd $BUILD_DIR
-```
-
-For building on Linux:
-
-```bash
-cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX="$(pwd)/install" $SOURCE_DIR
-# "Release" (for CMAKE_BUILD_TYPE) could also be "Debug" or "RelWithDebInfo"
-```
-
-For building on Android:
-```bash
-cmake $SOURCE_DIR -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$(pwd)/install" -DANDROID_ABI=arm64-v8a -DCMAKE_BUILD_TYPE=Release -DANDROID_STL=c++_static -DANDROID_PLATFORM=android-24 -DCMAKE_SYSTEM_NAME=Android -DANDROID_TOOLCHAIN=clang -DANDROID_ARM_MODE=arm -DCMAKE_MAKE_PROGRAM=$ANDROID_NDK_ROOT/prebuilt/linux-x86_64/bin/make -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK_ROOT/build/cmake/android.toolchain.cmake
-# If on Windows will be -DCMAKE_MAKE_PROGRAM=%ANDROID_NDK_ROOT%\prebuilt\windows-x86_64\bin\make.exe
-# -G is needed for building on Windows
-# -DANDROID_ABI can also be armeabi-v7a for 32 bit
-```
-
-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).
-
-Also, consider using `git config --global core.fileMode false` (or with `--local`) on Windows
-to prevent the addition of execution permission on files.
-
-#### 4) Build and Install
-
-```bash
-# for Linux:
-make -j4 install
-
-# for Windows:
-cmake --build . --config Release --target install
-# "Release" (for --config) could also be "Debug", "MinSizeRel", or "RelWithDebInfo"
-```
-
-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
-m4 -P MachineIndependent/glslang.m4 > MachineIndependent/glslang.y
-bison --defines=MachineIndependent/glslang_tab.cpp.h
-      -t MachineIndependent/glslang.y
-      -o MachineIndependent/glslang_tab.cpp
-```
-
-The above commands are also available in the bash script in `updateGrammar`,
-when executed from the glslang subdirectory of the glslang repository.
-With no arguments it builds the full grammar, and with a "web" argument,
-the web grammar subset (see more about the web subset in the next section).
-
-### Building to WASM for the Web and Node
-### Building a standalone JS/WASM library for the Web and Node
-
-Use the steps in [Build Steps](#build-steps), with the following notes/exceptions:
-* `emsdk` needs to be present in your executable search path, *PATH* for
-  Bash-like environments:
-  + [Instructions located here](https://emscripten.org/docs/getting_started/downloads.html#sdk-download-and-install)
-* Wrap cmake call: `emcmake cmake`
-* Set `-DBUILD_TESTING=OFF -DENABLE_OPT=OFF -DINSTALL_GTEST=OFF`.
-* Set `-DENABLE_HLSL=OFF` if HLSL is not needed.
-* For a standalone JS/WASM library, turn on `-DENABLE_GLSLANG_JS=ON`.
-* For building a minimum-size web subset of core glslang:
-  + turn on `-DENABLE_GLSLANG_WEBMIN=ON` (disables HLSL)
-  + execute `updateGrammar web` from the glslang subdirectory
-    (or if using your own scripts, `m4` needs a `-DGLSLANG_WEB` argument)
-  + optionally, for GLSL compilation error messages, turn on
-    `-DENABLE_GLSLANG_WEBMIN_DEVEL=ON`
-* To get a fully minimized build, make sure to use `brotli` to compress the .js
-  and .wasm files
-
-Example:
-
-```sh
-emcmake cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GLSLANG_JS=ON \
-    -DENABLE_HLSL=OFF -DBUILD_TESTING=OFF -DENABLE_OPT=OFF -DINSTALL_GTEST=OFF ..
-```
-
-## Building glslang - Using vcpkg
-
-You can download and install glslang using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
-
-    git clone https://github.com/Microsoft/vcpkg.git
-    cd vcpkg
-    ./bootstrap-vcpkg.sh
-    ./vcpkg integrate install
-    ./vcpkg install glslang
-
-The glslang port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
-
-## 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
-```
-
-If some tests fail with validation errors, there may be a mismatch between the
-version of `spirv-val` on the system and the version of glslang.  In this
-case, it is necessary to run `update_glslang_sources.py`.  See "Check-Out
-External Projects" above for more details.
-
-### 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, here with suggested calls
-for generating SPIR-V:
-
-```cxx
-const char* GetEsslVersionString();
-const char* GetGlslVersionString();
-bool InitializeProcess();
-void FinalizeProcess();
-
-class TShader
-    setStrings(...);
-    setEnvInput(EShSourceHlsl or EShSourceGlsl, stage,  EShClientVulkan or EShClientOpenGL, 100);
-    setEnvClient(EShClientVulkan or EShClientOpenGL, EShTargetVulkan_1_0 or EShTargetVulkan_1_1 or EShTargetOpenGL_450);
-    setEnvTarget(EShTargetSpv, EShTargetSpv_1_0 or EShTargetSpv_1_3);
-    bool parse(...);
-    const char* getInfoLog();
-
-class TProgram
-    void addShader(...);
-    bool link(...);
-    const char* getInfoLog();
-    Reflection queries
-```
-
-For just validating (not generating code), substitute these calls:
-
-```cxx
-    setEnvInput(EShSourceHlsl or EShSourceGlsl, stage,  EShClientNone, 0);
-    setEnvClient(EShClientNone, 0);
-    setEnvTarget(EShTargetNone, 0);
-```
-
-See `ShaderLang.h` and the usage of it in `StandAlone/StandAlone.cpp` for more
-details. There is a block comment giving more detail above the calls for
-`setEnvInput, setEnvClient, and setEnvTarget`.
-
-### C Functional Interface (original)
-
-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 back end 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 propagated 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`
-
-* Features can be protected by version/extension/stage/profile:
-  See the comment in `glslang/MachineIndependent/Versions.cpp`.

-// 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.
