Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code
generation. Glslang proper requires use of two licenses, one that covers
non-preprocessing and an additional one that covers preprocessing.
Bison was removed long ago. You can build glslang from the source grammar,
using tools of your choice, without using bison or any bison files.
Other parts, outside of glslang proper, include:
- gl_types.h, only needed for OpenGL-like reflection, and can be left out of
a parse and codegen project. See it for its license.
- update_glslang_sources.py, which is not part of the project proper and does
not need to be used.
- the SPIR-V "remapper", which is optional, but has the same license as
glslang proper
- Google tests and SPIR-V tools, and anything in the external subdirectory
are external and optional; see them for their respective licenses.

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.
MAP_TYPES = canonicalize type IDs
MAP_NAMES = canonicalize named data
MAP_FUNCS = canonicalize function bodies
DCE_FUNCS = remove dead functions
DCE_VARS = remove dead variables
DCE_TYPES = remove dead types
OPT_LOADSTORE = optimize unneeded load/stores
MAP_ALL = (MAP_TYPES | MAP_NAMES | MAP_FUNCS)
DCE_ALL = (DCE_FUNCS | DCE_VARS | DCE_TYPES)
OPT_ALL = (OPT_LOADSTORE)
ALL_BUT_STRIP = (MAP_ALL | DCE_ALL | OPT_ALL)
DO_EVERYTHING = (STRIP | ALL_BUT_STRIP)

# News
[![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)
## 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`.

// 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.

// Access chain design for an R-Value vs. L-Value:

// Expressions can be r-values, l-values, or both, or only r-values:
// a[b.c].d = .... // l-value
// ... = a[b.c].d; // r-value, that also looks like an l-value

// r-values should only be computed when they are needed, not speculatively.
//
// Computing an l-value means saving away information for later use in the compiler,
// no code is generated until the l-value is later dereferenced. It is okay
// to speculatively generate an l-value, just not okay to speculatively dereference it.
//
// The base of the access chain (the left-most variable or expression
// from which everything is based) can be set either as an l-value
// or as an r-value. Most efficient would be to set an l-value if one
// is available. If an expression was evaluated, the resulting r-value

//
// Symbol table for parsing. Has these design characteristics:
//
// * Same symbol table can be used to compile many shaders, to preserve
// effort of creating and loading with the large numbers of built-in
// symbols.
//
// --> This requires a copy mechanism, so initial pools used to create
// the shared information can be popped. Done through "clone"
// methods.
//
// * Name mangling will be used to give each function a unique name
// so that symbol table lookups are never ambiguous. This allows
// a simpler symbol table structure.
//
// * Pushing and popping of scope, so symbol table will really be a stack
// of symbol tables. Searched from the top, with new inserts going into
// the top.
//
// * Constants: Compile time constant symbols will keep their values
// in the symbol table. The parser can substitute constants at parse
// time, including doing constant folding and constant propagation.
//
// * No temporaries: Temporaries made from operations (+, --, .xy, etc.)
// are tracked in the intermediate representation, not the symbol table.
