From 509409ef11e3b1abd1d7e1bfb540bc172aa1a817 Mon Sep 17 00:00:00 2001 From: Anders Leino Date: Mon, 7 Oct 2024 20:16:19 +0300 Subject: Add WGSL support for slang-test (#5174) * Use the assembly description as target when disassembling I believe this is a bugfix. It seems to have worked before because up until the WGSL case, the disassembler has been the same executable as the one producing the binary to be disassembled. * Add Tint as a downstream compiler This closes issue #5104. * Add downstream compiler for Tint. * Tint is wrapped in a shared library, 'slang-tint' available from [1]. * The header file for slang-tint.dll is added in external/slang-tint-headers. * Add some boilerplate for WGSL targets. * Add an entry point test for WGSL. [1] https://github.com/shader-slang/dawn/releases/tag/slang-tint-0 * Add WGSL_SPIRV as supported target for Glslang * Add WebGPU support to slang-test This helps to address issue #5051. * Disable lots of crashing compute tests for 'wgpu' This closes issue #5051. --------- Co-authored-by: Yong He --- source/compiler-core/slang-tint-compiler.cpp | 164 +++++++++++++++++++++++++++ 1 file changed, 164 insertions(+) create mode 100644 source/compiler-core/slang-tint-compiler.cpp (limited to 'source/compiler-core/slang-tint-compiler.cpp') diff --git a/source/compiler-core/slang-tint-compiler.cpp b/source/compiler-core/slang-tint-compiler.cpp new file mode 100644 index 000000000..6319ecf9f --- /dev/null +++ b/source/compiler-core/slang-tint-compiler.cpp @@ -0,0 +1,164 @@ +#include "slang-tint-compiler.h" + +#include "slang-artifact-associated-impl.h" + +#include "../../external/slang-tint-headers/slang-tint.h" + +namespace Slang +{ + + class TintDownstreamCompiler : public DownstreamCompilerBase + { + + public: + + // IDownstreamCompiler + virtual SLANG_NO_THROW SlangResult SLANG_MCALL compile( + const CompileOptions& options, IArtifact** outResult) SLANG_OVERRIDE; + + virtual SLANG_NO_THROW bool SLANG_MCALL canConvert( + const ArtifactDesc& from, const ArtifactDesc& to) SLANG_OVERRIDE; + + virtual SLANG_NO_THROW SlangResult SLANG_MCALL convert( + IArtifact* from, const ArtifactDesc& to, IArtifact** outArtifact) + SLANG_OVERRIDE; + + virtual SLANG_NO_THROW bool SLANG_MCALL isFileBased() SLANG_OVERRIDE + { + return false; + } + + virtual SLANG_NO_THROW SlangResult SLANG_MCALL getVersionString( + slang::IBlob** outVersionString) SLANG_OVERRIDE; + + SlangResult compile(IArtifact *const sourceArtifact, IArtifact** outArtifact); + + SlangResult init(ISlangSharedLibrary* library); + + protected: + + ComPtr m_sharedLibrary; + + private: + + tint_CompileFunc m_compile; + tint_FreeResultFunc m_freeResult; + }; + + SlangResult TintDownstreamCompiler::init(ISlangSharedLibrary* library) + { + tint_CompileFunc compile = + (tint_CompileFunc)library->findFuncByName("tint_compile"); + if (compile == nullptr) + { + return SLANG_FAIL; + } + + tint_FreeResultFunc freeResult = + (tint_FreeResultFunc)library->findFuncByName("tint_free_result"); + if (freeResult == nullptr) + { + return SLANG_FAIL; + } + + m_sharedLibrary = library; + m_desc = Desc(SLANG_PASS_THROUGH_TINT); + m_compile = compile; + m_freeResult = freeResult; + return SLANG_OK; + } + + SlangResult TintDownstreamCompilerUtil::locateCompilers( + const String& path, + ISlangSharedLibraryLoader* loader, + DownstreamCompilerSet* set) + { + ComPtr library; + SLANG_RETURN_ON_FAIL(DownstreamCompilerUtil::loadSharedLibrary( + path, loader, nullptr, "slang-tint", library)); + SLANG_ASSERT(library); + + ComPtr compiler = ComPtr( + new TintDownstreamCompiler()); + SLANG_RETURN_ON_FAIL(static_cast( + compiler.get())->init(library)); + + set->addCompiler(compiler); + return SLANG_OK; + } + + SlangResult TintDownstreamCompiler::compile( + const CompileOptions& options, IArtifact** outArtifact) + { + IArtifact * sourceArtifact = options.sourceArtifacts[0]; + return compile(sourceArtifact, outArtifact); + } + + SlangResult TintDownstreamCompiler::compile( + IArtifact *const sourceArtifact, IArtifact** outArtifact) + { + tint_CompileRequest req = {}; + + if (sourceArtifact == nullptr) + return SLANG_FAIL; + + ComPtr sourceBlob; + SLANG_RETURN_FALSE_ON_FAIL(sourceArtifact->loadBlob( + ArtifactKeep::Yes, sourceBlob.writeRef())); + + String wgslCode( + (char*)sourceBlob->getBufferPointer(), + (char*)sourceBlob->getBufferPointer() + sourceBlob->getBufferSize()); + req.wgslCode = wgslCode.begin(); + req.wgslCodeLength = wgslCode.getLength(); + + tint_CompileResult result = {}; + SLANG_DEFER(m_freeResult(&result)); + bool compileSucceeded = m_compile(&req, &result) == 0; + + ComPtr spirvBlob = RawBlob::create(result.buffer, result.bufferSize); + result.buffer = nullptr; + + ComPtr resultArtifact = ArtifactUtil::createArtifactForCompileTarget( + SlangCompileTarget::SLANG_WGSL_SPIRV); + auto diagnostics = ArtifactDiagnostics::create(); + diagnostics->setResult(compileSucceeded ?
