This test reproduces a bug in Nvidia drivers: error: binding mismatch between shaders for UBO (named __defaultname) error: struct type mismatch between shaders for uniform (named __defaultname) error: binding mismatch between shaders for UBO (named __defaultname) error: struct type mismatch between shaders for uniform (named __defaultname) error: binding mismatch between shaders for UBO (named __defaultname) error: struct type mismatch between shaders for uniform (named __defaultname) error: binding mismatch between shaders for UBO (named __defaultname) error: struct type mismatch between shaders for uniform (named __defaultname)
The same issue is also present when SPIR-V debug names for uniform blocks are the same. --- .../unnamed-uniform-blocks.shader_test | 67 +++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 tests/spec/arb_gl_spirv/linker/uniform/unnamed-uniform-blocks.shader_test diff --git a/tests/spec/arb_gl_spirv/linker/uniform/unnamed-uniform-blocks.shader_test b/tests/spec/arb_gl_spirv/linker/uniform/unnamed-uniform-blocks.shader_test new file mode 100644 index 000000000000..9dba7d44c37d --- /dev/null +++ b/tests/spec/arb_gl_spirv/linker/uniform/unnamed-uniform-blocks.shader_test @@ -0,0 +1,67 @@ +# Test unnamed uniform blocks with the same structure + +[require] +SPIRV YES +GL >= 3.3 +GLSL >= 4.50 + +[compute shader spirv] +; SPIR-V +; Version: 1.0 +; Generator: Khronos Glslang Reference Front End; 7 +; Bound: 33 +; Schema: 0 + OpCapability Shader + %1 = OpExtInstImport "GLSL.std.450" + OpMemoryModel Logical GLSL450 + OpEntryPoint GLCompute %4 "main" + OpExecutionMode %4 LocalSize 1 1 1 + OpDecorate %9 Location 2 + OpDecorate %9 DescriptorSet 0 + OpDecorate %_arr_v4uint_uint_4 ArrayStride 16 + OpMemberDecorate %_struct_18 0 Offset 0 + OpDecorate %_struct_18 Block + OpDecorate %20 DescriptorSet 0 + OpDecorate %20 Binding 0 + OpDecorate %_arr_v4uint_uint_4_0 ArrayStride 16 + OpMemberDecorate %_struct_26 0 Offset 0 + OpDecorate %_struct_26 Block + OpDecorate %28 DescriptorSet 0 + OpDecorate %28 Binding 1 + %void = OpTypeVoid + %3 = OpTypeFunction %void + %uint = OpTypeInt 32 0 + %7 = OpTypeImage %uint 2D 0 0 0 2 Rgba32ui +%_ptr_UniformConstant_7 = OpTypePointer UniformConstant %7 + %9 = OpVariable %_ptr_UniformConstant_7 UniformConstant + %int = OpTypeInt 32 1 + %v2int = OpTypeVector %int 2 + %int_0 = OpConstant %int 0 + %14 = OpConstantComposite %v2int %int_0 %int_0 + %v4uint = OpTypeVector %uint 4 + %uint_4 = OpConstant %uint 4 +%_arr_v4uint_uint_4 = OpTypeArray %v4uint %uint_4 + %_struct_18 = OpTypeStruct %_arr_v4uint_uint_4 +%_ptr_Uniform__struct_18 = OpTypePointer Uniform %_struct_18 + %20 = OpVariable %_ptr_Uniform__struct_18 Uniform + %uint_0 = OpConstant %uint 0 +%_ptr_Uniform_uint = OpTypePointer Uniform %uint +%_arr_v4uint_uint_4_0 = OpTypeArray %v4uint %uint_4 + %_struct_26 = OpTypeStruct %_arr_v4uint_uint_4_0 +%_ptr_Uniform__struct_26 = OpTypePointer Uniform %_struct_26 + %28 = OpVariable %_ptr_Uniform__struct_26 Uniform + %4 = OpFunction %void None %3 + %5 = OpLabel + %10 = OpLoad %7 %9 + %23 = OpAccessChain %_ptr_Uniform_uint %20 %int_0 %int_0 %uint_0 + %24 = OpLoad %uint %23 + %29 = OpAccessChain %_ptr_Uniform_uint %28 %int_0 %int_0 %uint_0 + %30 = OpLoad %uint %29 + %31 = OpIAdd %uint %24 %30 + %32 = OpCompositeConstruct %v4uint %31 %31 %31 %31 + OpImageWrite %10 %14 %32 + OpReturn + OpFunctionEnd + +[test] +link success -- 2.18.1 _______________________________________________ Piglit mailing list Piglit@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/piglit
