Handle complex cases in Inspector::GenerateSamplerTargets This code was implicitly assuming that all resources it was looking for would be directly referenced at the intrinsic callsite, and not passed via function parameters. This was causing a crash in more complex cases. The inspector code has been updated to handle cases where the resources are not being directly referenced. Unneeded calls to GenerateSamplerTargets() are removed. Utility function GetOriginatingResources() is added to handle walking up call sites to resolve resources. Text shader based test runner is added to the Inspector tests to make expressing complex tests easier.

Tint is a compiler for the WebGPU Shader Language (WGSL).
This is not an officially supported Google product.

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.
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
.
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
