This adds SPIR-V assembly and WGSL tests derived from VK-GL-CTS commit 571256871c2e2f03995373e1e4a02958d8cd8cf5. The following procedure was followed: - Those .amber files in VK-GL-CTS wholly owned by Google were identified - All GLSL and SPIR-V shaders were extracted from the Amber files and converted into SPIR-V binaries - The compact-ids pass of spirv-opt was applied to each binary - Duplicate binaries were removed - spirv-opt -O was used to obtain an optimized version of each remaining binary, with duplicates discarded - Binaries that failed validation using spirv-val with target environment SPIR-V 1.3 were discarded - Those binaries that tint could not successfully convert into WGSL were put aside for further investigation - SPIR-V assembly versions of the remaining binaries are included in this CL - test-runner with -generate-expected and -generate-skip was used to generate expected .spvasm, .msl, .hlsl and .wgsl outputs for these SPIR-V assembly tests - Each successfully-generated .expected.wgsl is included in this CL again, as a WGLSL test - test-runner with -generate-expected and -generate-skip was used again, to generate expected outputs for these WGSL tests Change-Id: Ibe9baf2729cf97e0b633db9a426f53362a5de540 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/58842 Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Ben Clayton <bclayton@google.com> Reviewed-by: Ben Clayton <bclayton@google.com>
