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
members, 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)

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 includes where to get binaries, and is kept up to date
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 two components:
1. A front-end library for programmatic parsing of GLSL/ESSL into an AST.
2. A standalone wrapper, `glslangValidator`, that can be used as a shader
validation tool.
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 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
```
#### 2) 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 $SOURCE_DIR -DCMAKE_INSTALL_PREFIX=`pwd`/install
# The CMAKE_INSTALL_PREFIX part is for testing (explained later).
```
The CMake GUI also works for Windows (version 3.4.1 tested).
#### 3) Build and Install
```bash
# for Linux:
ninja install
# for Windows:
cmake --build . --config {Release|Debug|MinSizeRel|RelWithDebInfo} \
--target install
```
If using MSVC, after running CMake to configure, use the
Configuration Manager to check the `INSTALL` project.
### If you need to change the GLSL grammar
The grammar in `glslang/MachineIndependent/glslang.y` has to be recompiled with
bison if it changes, the output files are committed to the repo to avoid every
developer needing to have bison configured to compile the project when grammar
changes are quite infrequent. For windows you can get binaries from
[GnuWin32][bison-gnu-win32].
The command to rebuild is:
```bash
bison --defines=MachineIndependent/glslang_tab.cpp.h
-t MachineIndependent/glslang.y
-o MachineIndependent/glslang_tab.cpp
```
The above command is also available in the bash script at
`glslang/updateGrammar`.
Testing
-------
Right now, there are two test harnesses existing in glslang: one is [Google
Test](gtests/), one is the [`runtests` script](Test/runtests). The former
runs unit tests and single-shader single-threaded integration tests, while
the latter runs multiple-shader linking tests and multi-threaded tests.
### Running tests
The [`runtests` script](Test/runtests) requires compiled binaries to be
installed into `$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.

// Enumeration tokens for SPIR-V, in various styles:
// C, C++, C++11, JSON, Lua, Python
//
// - C will have tokens with a "Spv" prefix, e.g.: SpvSourceLanguageGLSL
// - 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
// - Lua will use tables, e.g.: spv.SourceLanguage.GLSL
// - Python will use dictionaries, e.g.: spv['SourceLanguage']['GLSL']
//
// Some tokens act like mask values, which can be OR'd together,
// while others are mutually exclusive. The mask-like ones have
// "Mask" in their name, and a parallel enum that has the shift
// amount (1 << x) for each corresponding enumerant.

//
// 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.

// Help manage multiple profiles, versions, extensions etc.
//
// These don't return error codes, as the presumption is parsing will
// always continue as if the tested feature were enabled, and thus there
// is no error recovery needed.
//
//
// HOW TO add a feature enabled by an extension.
//
// To add a new hypothetical "Feature F" to the front end, where an extension
// "XXX_extension_X" can be used to enable the feature, do the following.
//
// OVERVIEW: Specific features are what are error-checked for, not
// extensions: A specific Feature F might be enabled by an extension, or a
// particular version in a particular profile, or a stage, or combinations, etc.
//
// The basic mechanism is to use the following to "declare" all the things that
// enable/disable Feature F, in a code path that implements Feature F:
//
// requireProfile()
// profileRequires()
// requireStage()
// checkDeprecated()
// requireNotRemoved()
// requireExtensions()
//
// Typically, only the first two calls are needed. 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. Establish them at
// the earliest release that supports the extension. Then, tag them with the
// set of extensions that both enable them and are necessary, given the version of the symbol
// table. (There is a different symbol table for each version.)
