Cleanup duplicate files; Combine README and build docs.
This PR cleans up some of the documentation post Dawn+Tint merge. The README is better combined, the building document is moved up a level as it covers both Tint and Dawn. The various duplicate files are removed.

# Tint
|
||||
|
||||
Tint is a compiler for the WebGPU Shader Language (WGSL).
|
||||
|
||||
This is not an officially supported Google product.
|
||||
|
||||
## Requirements
|
||||
* Git
|
||||
* CMake (3.10.2 or later)
|
||||
* Ninja (or other build tool)
|
||||
* Python, for fetching dependencies
|
||||
* [depot_tools] in your path
|
||||
|
||||
## Build options
|
||||
* `TINT_BUILD_SPV_READER` : enable the SPIR-V input reader (off by default)
|
||||
* `TINT_BUILD_WGSL_READER` : enable the WGSL input reader (on by default)
|
||||
* `TINT_BUILD_SPV_WRITER` : enable the SPIR-V output writer (on by default)
|
||||
* `TINT_BUILD_WGSL_WRITER` : enable the WGSL output writer (on by default)
|
||||
* `TINT_BUILD_FUZZERS` : enable building fuzzzers (off by default)
|
||||
|
||||
## Building
|
||||
Tint uses Chromium dependency management so you need to install [depot_tools]
|
||||
and add it to your PATH.
|
||||
|
||||
[depot_tools]: http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
|
||||
|
||||
### Getting source & dependencies
|
||||
|
||||
```sh
|
||||
# Clone the repo as "tint"
|
||||
git clone https://dawn.googlesource.com/tint tint
|
||||
cd tint
|
||||
|
||||
# Bootstrap the gclient configuration
|
||||
cp scripts/standalone.gclient .gclient
|
||||
|
||||
# Fetch external dependencies and toolchains with gclient
|
||||
gclient sync
|
||||
```
|
||||
|
||||
### Compiling using CMake + Ninja
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
cd out/Debug
|
||||
cmake -GNinja ../..
|
||||
ninja # or autoninja
|
||||
```
|
||||
|
||||
### Compiling using CMake + make
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
cd out/Debug
|
||||
cmake ../..
|
||||
make # -j N for N-way parallel build
|
||||
```
|
||||
|
||||
### Compiling using gn + ninja
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
gn gen out/Debug
|
||||
autoninja -C out/Debug
|
||||
```
|
||||
|
||||
### Fuzzers on MacOS
|
||||
If you are attempting fuzz, using `TINT_BUILD_FUZZERS=ON`, the version of llvm
|
||||
in the XCode SDK does not have the needed libfuzzer functionality included.
|
||||
|
||||
The build error that you will see from using the XCode SDK will look something
|
||||
like this:
|
||||
```
|
||||
ld: file not found:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/11.0.0/lib/darwin/libclang_rt.fuzzer_osx.a
|
||||
```
|
||||
|
||||
The solution to this problem is to use a full version llvm, like what you would
|
||||
get via homebrew, `brew install llvm`, and use something like `CC=<path to full
|
||||
clang> cmake ..` to setup a build using that toolchain.
|
||||
|
||||
### Checking [chromium-style] issues in CMake builds
|
||||
The gn based work flow uses the Chromium toolchain for building in anticipation
|
||||
of integration of Tint into Chromium based projects. This toolchain has
|
||||
additional plugins for checking for style issues, which are marked with
|
||||
[chromium-style] in log messages. This means that this toolchain is more strict
|
||||
then the default clang toolchain.
|
||||
|
||||
In the future we will have a CQ that will build this work flow and flag issues
|
||||
automatically. Until that is in place, to avoid causing breakages you can run
|
||||
the [chromium-style] checks using the CMake based work flows. This requires
|
||||
setting `CC` to the version of clang checked out by `gclient sync` and setting
|
||||
the `TINT_CHECK_CHROMIUM_STYLE` to `ON`.
|
||||
|
||||
```sh
|
||||
mkdir -p out/style
|
||||
cd out/style
|
||||
cmake ../..
|
||||
CC=../../third_party/llvm-build/Release+Asserts/bin/clang cmake -DTINT_CHECK_CHROMIUM_STYLE=ON ../../ # add -GNinja for ninja builds
|
||||
```

# Dawn, a WebGPU implementation
|
||||
|
||||
Dawn is an open-source and cross-platform implementation of the work-in-progress [WebGPU](https://webgpu.dev) standard.
|
||||
More precisely it implements [`webgpu.h`](https://github.com/webgpu-native/webgpu-headers/blob/main/webgpu.h) that is a one-to-one mapping with the WebGPU IDL.
|
||||
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
|
||||
|
||||
Dawn provides several WebGPU building blocks:
|
||||
- **WebGPU C/C++ headers** that applications and other building blocks use.
|
||||
- The `webgpu.h` version that Dawn implements.
|
||||
- A C++ wrapper for the `webgpu.h`.
|
||||
- **A "native" implementation of WebGPU** using platforms' GPU APIs:
|
||||
- **D3D12** on Windows 10
|
||||
- **Metal** on macOS and iOS
|
||||
- **Vulkan** on Windows, Linux, ChromeOS, Android and Fuchsia
|
||||
- OpenGL as best effort where available
|
||||
- **A client-server implementation of WebGPU** for applications that are in a sandbox without access to native drivers
|
||||

|
||||
## Building
|
||||
Tint uses Chromium dependency management so you need to install [depot_tools]
|
||||
and add it to your PATH.
|
||||
|
||||
[depot_tools]: http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
|
||||
|
||||
### Getting source & dependencies
|
||||
|
||||
```sh
|
||||
# Clone the repo as "tint"
|
||||
git clone https://dawn.googlesource.com/tint tint
|
||||
cd tint
|
||||
|
||||
# Bootstrap the gclient configuration
|
||||
cp scripts/standalone.gclient .gclient
|
||||
|
||||
# Fetch external dependencies and toolchains with gclient
|
||||
gclient sync
|
||||
```
|
||||
|
||||
### Compiling using CMake + Ninja
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
cd out/Debug
|
||||
cmake -GNinja ../..
|
||||
ninja # or autoninja
|
||||
```
|
||||
|
||||
### Compiling using CMake + make
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
cd out/Debug
|
||||
cmake ../..
|
||||
make # -j N for N-way parallel build
|
||||
```
|
||||
|
||||
### Compiling using gn + ninja
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
gn gen out/Debug
|
||||
autoninja -C out/Debug
|
||||
```
|
||||
|
||||
### Fuzzers on MacOS
|
||||
If you are attempting fuzz, using `TINT_BUILD_FUZZERS=ON`, the version of llvm
|
||||
in the XCode SDK does not have the needed libfuzzer functionality included.
|
||||
|
||||
The build error that you will see from using the XCode SDK will look something
|
||||
like this:
|
||||
```
|
||||
ld: file not found:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/11.0.0/lib/darwin/libclang_rt.fuzzer_osx.a
|
||||
```
|
||||
|
||||
The solution to this problem is to use a full version llvm, like what you would
|
||||
get via homebrew, `brew install llvm`, and use something like `CC=<path to full
|
||||
clang> cmake ..` to setup a build using that toolchain.
|
||||
|
||||
### Checking [chromium-style] issues in CMake builds
|
||||
The gn based work flow uses the Chromium toolchain for building in anticipation
|
||||
of integration of Tint into Chromium based projects. This toolchain has
|
||||
additional plugins for checking for style issues, which are marked with
|
||||
[chromium-style] in log messages. This means that this toolchain is more strict
|
||||
then the default clang toolchain.
|
||||
|
||||
In the future we will have a CQ that will build this work flow and flag issues
|
||||
automatically. Until that is in place, to avoid causing breakages you can run
|
||||
the [chromium-style] checks using the CMake based work flows. This requires
|
||||
setting `CC` to the version of clang checked out by `gclient sync` and setting
|
||||
the `TINT_CHECK_CHROMIUM_STYLE` to `ON`.
|
||||
|
||||
```sh
|
||||
mkdir -p out/style
|
||||
cd out/style
|
||||
cmake ../..
|
||||
CC=../../third_party/llvm-build/Release+Asserts/bin/clang cmake -DTINT_CHECK_CHROMIUM_STYLE=ON ../../ # add -GNinja for ninja builds
|
||||
```

# Building Dawn
|
||||
|
||||
## System requirements
|
||||
|
||||
* Git
|
||||
* CMake (3.10.2 or later) (if desired)
|
||||
* GN (if desired)
|
||||
* Ninja (or other build tool)
|
||||
* Python, for fetching dependencies
|
||||
* [depot_tools] in your path
|
||||
|
||||
- Linux
|
||||
- The `pkg-config` command:
|
||||
```sh
|
||||
# Install pkg-config on Ubuntu
|
||||
sudo apt-get install pkg-config
|
||||
```
|
||||
|
||||
- Mac
|
||||
- [Xcode](https://developer.apple.com/xcode/) 12.2+.
|
||||
- The macOS 11.0 SDK. Run `xcode-select` to check whether you have it.
|
||||
```sh
|
||||
ls `xcode-select -p`/Platforms/MacOSX.platform/Developer/SDKs
|
||||
```
|
||||
|
||||
## Install `depot_tools`
|
||||
|
||||
Dawn uses the Chromium build system and dependency management so you need to [install depot_tools] and add it to the PATH.
|
||||
|
||||
[install depot_tools]: http://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
|
||||
|
||||
## Get the code
|
||||
|
||||
```sh
|
||||
# Clone the repo as "dawn"
|
||||
git clone https://dawn.googlesource.com/dawn dawn && cd dawn
|
||||
|
||||
# Bootstrap the gclient configuration
|
||||
cp scripts/standalone.gclient .gclient
|
||||
|
||||
# Fetch external dependencies and toolchains with gclient
|
||||
gclient sync
|
||||
```
|
||||
|
||||
## Build Dawn
|
||||
|
||||
### Compiling using CMake + Ninja
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
cd out/Debug
|
||||
cmake -GNinja ../..
|
||||
ninja # or autoninja
|
||||
```
|
||||
|
||||
### Compiling using CMake + make
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
cd out/Debug
|
||||
cmake ../..
|
||||
make # -j N for N-way parallel build
|
||||
```
|
||||
|
||||
### Compiling using gn + ninja
|
||||
```sh
|
||||
mkdir -p out/Debug
|
||||
gn gen out/Debug
|
||||
autoninja -C out/Debug
|
||||
```
|
||||
|
||||
The most common GN build option is `is_debug=true/false`; otherwise
|
||||
`gn args out/Debug --list` shows all the possible options.
|
||||
|
||||
On macOS you'll want to add the `use_system_xcode=true` in most cases.
|
||||
(and if you're a googler please get XCode from go/xcode).
|
||||
|
||||
|
||||

## Build Dawn
|
||||
|
||||
Then generate build files using `gn args out/Debug` or `gn args out/Release`.
|
||||
A text editor will appear asking build options, the most common option is `is_debug=true/false`; otherwise `gn args out/Release --list` shows all the possible options.
|
||||
|
||||
On macOS you'll want to add the `use_system_xcode=true` in most cases. (and if you're a googler please get XCode from go/xcode).
|
||||
|
||||
Then use `ninja -C out/Release` to build dawn and for example `./out/Release/dawn_end2end_tests` to run the tests.
