Olli Etuaho 3de2703d 2017-11-30T12:16:47 Fix handling matrix qualifiers on block members Individual block member row_major/column_major layout qualifiers may override the qualifiers set on the block. During parsing, this was already being handled correctly, so that the qualifier is resolved for each block member and recorded for each TField / InterfaceBlockField. Now we always write the qualifiers on a per-member granularity to the output GLSL shaders, so that the native driver gets the correct per-member qualifiers. This replaces earlier behavior where the matrix qualifiers were only written per-block. Also only use qualifiers from individual members in block layout. Since the block-level qualifier information is no longer used after parsing, it is no longer kept in the AST. A dummy value is still set to the InterfaceBlock structs exposed through the ShaderVars interface, since that has existing usage in Chromium that needs to be removed before the field can be removed. Some AMD OpenGL drivers don't seem to handle matrix layout qualifiers correctly, so most of the added tests need to be skipped for AMD GL. On NVIDIA and Intel the tests pass.

They will be removed unless their initializer has side effects. The CollectVariables step needs to be run after the pruning, as the pruning may affect which interface variables are statically used. It's also good to gather built-ins that need to be emulated after the pruning, so unnecessary built-in emulation functions are not added to the translator output. This will help handle some dEQP tests for arrays of arrays that have extremely large local arrays that are only used in an array length query. By constant folding the length and pruning unused variables we will avoid adding a large amount of array initialization code to the generated shaders.

The resulting shader could also end up very long. Initialize most arrays using a simple for loop instead. The loop is compatible with ESSL 1.00 Appendix A limitations. An exception is made for fragment outputs, so that they are not indexed by non-constant values. On some platforms using the a loop to initialize variables can cause problems, so we also have a compiler flag for turning this behavior off.

Olli Etuaho 661fc487 2017-10-16T12:17:05 Work around NVIDIA GLSL vector-scalar op bug This adds a new AST transform VectorizeVectorScalarArithmetic. The AST transform works around incorrect handling of certain types of GLSL arithmetic operations by NVIDIA's GL driver. It works around only the most common cases where the bug reproduces, since detecting all the cases would take more sophisticated analysis of the code than what is currently easily implementable in ANGLE. When a float add operator has both vector and scalar operands, the AST transform turns the scalar operand into a vector operand. Example: vec4 f; f += 1.0; gets turned into: vec4 f; f += vec4(1.0); When a vector constructor contains a binary scalar float multiplication or division operation as its only argument, the AST transform turns both operands of the binary operation into vector operands. Example: float f, g; vec4(f * g); gets turned into: float f, g; vec4(vec4(f) * vec4(g)); Another example with compound assignment: float f, g; vec4(f *= g); gets turned into: float f, g; vec4 s0 = vec4(f); (s0 *= g, f = s0.x), s0; This latter transformation only works in case the compound assignment left hand expression doesn't have side effects.

Olli Etuaho bd3cd506 2017-11-03T15:48:52 Clean up HLSL constructor output Split generating HLSL struct constructors from generating built-in type constructors, as these didn't have much in common. Struct constructors are now only generated when they are needed, as opposed to before, when they were generated on any use of a struct. This changes built-in constructor naming to include "_ctor" and gets rid of having special built-in type names just for constructors. This will make it easier to do changes to constructor output, for example to add constructors for structs in std140 layout. This might be needed to implement SSBOs efficiently. This includes one bug fix for writing out struct declarations for varyings. Also improves const-correctness of accessing structs through TType in general.

Olli Etuaho 2ef23e2d 2017-11-01T16:39:11 Fix writing uniform block maps to HLSL output HLSL output maps structs in std140 uniform blocks to a different layout in order to eliminate padding. The padding may have been inserted to comply with std140 packing rules. There used to be two issues in writing the maps: Sometimes the same map could be written multiple times, and the maps were not being written for uniform blocks with instance names. Rewrite how the uniform buffer struct maps get generated so that the code works correctly. Instead of flagging accesses, structs inside uniform blocks are gathered from uniform block declarations. When accesses to structs in uniform blocks are written out in OutputHLSL, it's checked whether a mapped struct needs to be used instead of the original one. This code could still be optimized further by limiting mapped structs generation to those ones that really need to be used. This is left to be done later.

Jamie Madill 76e471e9 2017-10-21T09:56:01 Vulkan: Implement basic uniforms. This implementation adds one descriptor set with two bindings: one for default vertex uniforms and the other for fragment. It adds two corresponding uniform buffers, and the logic for updating the descriptor sets bound to Vulkan. It doesn't handle much in the way of synchronization and dependency management, or uniform update. If there are only vertex or fragment uniforms the empty uniform buffer is omitted from the descriptor set. If both are missing, there is no descriptor set bound. Note that as our implementation progresses we might not be able to initialize our descriptor sets at link time, due to streaming in uniform data.

This is because PruneEmptyDeclarations will still remove empty declarations, and at least the NVIDIA driver GLSL compiler doesn't accept some types of no-op statements as the last statement inside a switch statement.

According to GLSL ES 3.1 SPEC (Chapter 4.4.1 and Chapter 4.4.2), 'location' layout qualifier is allowed on both inputs and outputs of vertex and fragment shaders. 'location' layout qualifier on shader interfaces is only valid on shaders whose version is 3.1 and above. According to GLSL ES 3.0 SPEC, vertex shader cannot have output layout qualifiers (Chapter 4.3.8.2) and fragment shader cannot have input layout qualifiers (Chapter 4.3.8.1). The 'location' qualifier on varyings is used in the shader interface matching defined in OpenGL ES 3.1. (OpenGL ES 3.1 SPEC Chapter 7.4.1). This new link rule will be added to Program.cpp in another patch. For the OpenGL ES 3.1 extension GL_OES_geometry_shader, according to GL_OES_shader_io_blocks SPEC (Chapter 4.4.1 and Chapter 4.4.2), 'location' layout qualifier is both valid on geometry shader inputs and outputs.
