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.

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().

If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.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): +/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) -> +``` + +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`. + +[cmake]: https://cmake.org/ +[python]: https://www.python.org/ +[bison]: https://www.gnu.org/software/bison/ +[googletest]: https://github.com/google/googletest +[bison-gnu-win32]: http://gnuwin32.sourceforge.net/packages/bison.htm +[master-tot-release]: https://github.com/KhronosGroup/glslang/releases/tag/master-tot diff --git a/dep/glslang/SPIRV/GLSL.ext.AMD.h b/dep/glslang/SPIRV/GLSL.ext.AMD.h new file mode 100644 index 000000000..009d2f1cf --- /dev/null +++ b/dep/glslang/SPIRV/GLSL.ext.AMD.h @@ -0,0 +1,108 @@ +/* +** Copyright (c) 2014-2016 The Khronos Group Inc. +** +** Permission is hereby granted, free of charge, to any person obtaining a copy +** of this software and/or associated documentation files (the "Materials"), +** to deal in the Materials without restriction, including without limitation +** the rights to use, copy, modify, merge, publish, distribute, sublicense, +** and/or sell copies of the Materials, and to permit persons to whom the +** Materials are furnished to do so, subject to the following conditions: +** +** The above copyright notice and this permission notice shall be included in +** all copies or substantial portions of the Materials. +** +** MODIFICATIONS TO THIS FILE MAY MEAN IT NO LONGER ACCURATELY REFLECTS KHRONOS +** STANDARDS.

They go into a code path that +// implements Feature F, and will log the proper error/warning messages. Parsing +// will then always continue as if the tested feature was enabled. +// +// There is typically no if-testing or conditional parsing, just insertion of the calls above. +// However, if symbols specific to the extension are added (step 5), they will +// only be added under tests that the minimum version and profile are present. +// +// 1) Add a symbol name for the extension string at the bottom of Versions.h: +// +// const char* const XXX_extension_X = "XXX_extension_X"; +// +// 2) Add extension initialization to TParseVersions::initializeExtensionBehavior(), +// the first function below: +// +// extensionBehavior[XXX_extension_X] = EBhDisable; +// +// 3) Add any preprocessor directives etc. in the next function, TParseVersions::getPreamble(): +// +// "#define XXX_extension_X 1\n" +// +// The new-line is important, as that ends preprocess tokens. +// +// 4) Insert a profile check in the feature's path (unless all profiles support the feature, +// for some version level). That is, call requireProfile() to constrain the profiles, e.g.: +// +// // ... in a path specific to Feature F... +// requireProfile(loc, +// ECoreProfile | ECompatibilityProfile, +// "Feature F"); +// +// 5) For each profile that supports the feature, insert version/extension checks: +// +// The mostly likely scenario is that Feature F can only be used with a +// particular profile if XXX_extension_X is present or the version is +// high enough that the core specification already incorporated it. +// +// // following the requireProfile() call... +// profileRequires(loc, +// ECoreProfile | ECompatibilityProfile, +// 420, // 0 if no version incorporated the feature into the core spec. +// XXX_extension_X, // can be a list of extensions that all add the feature +// "Feature F Description"); +// +// This allows the feature if either A) one of the extensions is enabled or +// B) the version is high enough. If no version yet incorporates the feature +// into core, pass in 0. +// +// This can be called multiple times, if different profiles support the +// feature starting at different version numbers or with different +// extensions. +// +// This must be called for each profile allowed by the initial call to requireProfile(). +// +// Profiles are all masks, which can be "or"-ed together. +// +// ENoProfile +// ECoreProfile +// ECompatibilityProfile +// EEsProfile +// +// The ENoProfile profile is only for desktop, before profiles showed up in version 150; +// All other #version with no profile default to either es or core, and so have profiles. +// +// You can select all but a particular profile using ~. The following basically means "desktop": +// +// ~EEsProfile +// +// 6) If built-in symbols are added by the extension, add them in Initialize.cpp: Their use +// will be automatically error checked against the extensions enabled at that moment. +// see the comment at the top of Initialize.cpp for where to put them.

The + // base offset of all other structure members is derived by taking the offset of the + // last basic machine unit consumed by the previous member and adding one. Each + // structure member is stored in memory at its aligned offset. The members of a top- + // level uniform block are laid out in buffer storage by treating the uniform block as + // a structure with a base offset of zero. + // + // 1. If the member is a scalar consuming N basic machine units, the base alignment is N. + // + // 2. If the member is a two- or four-component vector with components consuming N basic + // machine units, the base alignment is 2N or 4N, respectively. + // + // 3. If the member is a three-component vector with components consuming N + // basic machine units, the base alignment is 4N. + // + // 4. If the member is an array of scalars or vectors, the base alignment and array + // stride are set to match the base alignment of a single array element, according + // to rules (1), (2), and (3), and rounded up to the base alignment of a vec4. The + // array may have padding at the end; the base offset of the member following + // the array is rounded up to the next multiple of the base alignment. + // + // 5. If the member is a column-major matrix with C columns and R rows, the + // matrix is stored identically to an array of C column vectors with R + // components each, according to rule (4). + // + // 6. If the member is an array of S column-major matrices with C columns and + // R rows, the matrix is stored identically to a row of S X C column vectors + // with R components each, according to rule (4). + // + // 7. If the member is a row-major matrix with C columns and R rows, the matrix + // is stored identically to an array of R row vectors with C components each, + // according to rule (4). + // + // 8. If the member is an array of S row-major matrices with C columns and R + // rows, the matrix is stored identically to a row of S X R row vectors with C + // components each, according to rule (4). + // + // 9. If the member is a structure, the base alignment of the structure is N , where + // N is the largest base alignment value of any of its members, and rounded + // up to the base alignment of a vec4. The individual members of this substructure + // are then assigned offsets by applying this set of rules recursively, + // where the base offset of the first member of the sub-structure is equal to the + // aligned offset of the structure. The structure may have padding at the end; + // the base offset of the member following the sub-structure is rounded up to + // the next multiple of the base alignment of the structure. + // + // 10.
