[spirv-writer] Add start of break and continue. This CL adds the beginning of break and continue support. The conditional versions are not supported, just the non-conditional. Bug: tint:5 Change-Id: I84418cffd3e29dc011c4313bf9aa3da4833c009f Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/20500 Reviewed-by: David Neto <firstname.lastname@example.org>
Tint is a compiler for the WebGPU Shader Language (WGSL).
This is not an officially supported Google product.
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)
Tint uses Chromium dependency management so you need to install depot_tools and add it to your PATH.
# Clone the repo as "tint" git clone https://dawn.googlesource.com/tint tint && cd tint # Bootstrap the gclient configuration cp standalone.gclient .gclient # Fetch external dependencies and toolchains with gclient gclient sync
mkdir -p out/Debug cd out/Debug cmake -GNinja ../.. ninja # or autoninja
mkdir -p out/Debug cd out/Debug cmake ../.. make # -j N for N-way parallel build
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.
