0e1c90cf | 2021-07-21 10:24:26 | Translator: Validate function parameter qualifiers This change cleans up a confusion in EvqConst and EvqConstReadOnly, where the former was frequently used instead of the latter for function parameters. The change makes the following renames to make the intent of the relevant qualifiers clearer: EvqIn -> EvqParamIn EvqOut -> EvqParamOut EvqInOut -> EvqParamInOut EvqConstReadOnly -> EvqParamConst Bug: angleproject:4889 Change-Id: Idedd32c08a91de069b91b1657d6b783dddece04a Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3041622 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tim Van Patten <timvp@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> | |

6e261453 | 2021-07-20 22:34:33 | Vulkan: SPIR-V Gen: Fix I/O block arrays Since the qualifier on intermediate nodes are EvqTemporary, the code that autodeduced the block storage of I/O blocks was incorrectly assigning them std140 when an indexed I/O block array was encountered. This resulted in duplicate types in the SPIR-V. This is generally benign (other than creating an unnecessary type) except for gl_PerVertex as it adds BuiltIn decorations. gl_PerVertex may be an array in geometry and tessellation shaders.

05eb0a32 | 2021-07-19 16:14:34 | Translator: Allow subpassLoad in AST in ESSL subpassLoad is available to desktop GLSL, but not GLSL ES. With this change, subpassLoad is made available internally to the AST so that framebuffer fetch's use of this built-in can be simplified. Additionally, this makes the tree more consistent in that there's no function call without a corresponding function declaration. A follow up change will add an AST validation to enforce this.

a8807cbf | 2021-07-17 00:00:27 | Vulkan: SPIR-V Gen: Support interpolateAt* The interpolateAt* builtins take their first argument as a pointer, so only the OpAccessChain result should be given to the corresponding SPIR-V instruction. A test is written in this change to handle interpolateAt* when given a swizzled lvalue, which is not representable in SPIR-V. This can be supported by having the AST transform: interpolateAtX(value.zy) to: interpolateAtX(value).zy which can be done right when the function is parsed and the AST node for it is created (by taking the swizzle out of the parameter and applying it to the node). However, swizzled lvalues as parameter to interpolateAt* is only allowed in desktop GLSL, and so the test is disabled. From the GLSL ES3.2 spec: > Component selection operators (e.g. .xy) may not be used when > specifying interpolant.

In SPIR-V, they are translated as such: - modf and frexp: Returns the same result as GLSL, with a pointer to store the output parameter. Since SPIR-V cannot create pointers to swizzles, a temp variable is used in that case. - uaddCarry, usubBorrow, umulExtended and imulExtended: These return a struct in SPIR-V, which contains the two output parameters; with lsb in field 0 and msb in field 1.

b3cbfd55 | 2021-07-07 12:31:57 | Fix multiple end2end crashes in direct-to-MSL compiler. This set of changes: - Adds a single place (CompilerMtl::useDirectToMSLCompiler) where the direct-to-MSL compiler can be enabled, still at compile time rather than run time. It is still disabled by default. - Initializes MTLWaitableCompileEventImpl::mShader, without which all shader compiles crash. - Fixes a mismatch of the ANGLERasterizerDisabled variable name in the generated MSL. - Removes the transform feedback bindings as an argument to the vertex shader's main0(). Transform feedback support needs to be reimplemented in this compiler backend. - Added an option to the DriverUniform class to emit as either an interface block or a struct. The direct-to-MSL backend assumes it is a struct. - Disable variable reference validation when referencing either sample mask or rasterizer discard functionality in the shader. - Disable struct usage validation when inserting references to ANGLE_TextureEnv. This occurs during pipeline rewriting and it's infeasible to disable it at that point, so disable it during pipeline rewriting - which means it's disabled for all shaders. - For angle_end2end_tests, disable the file API hooking which disables the Metal shader cache. This speeds up the tests significantly - by roughly a factor of 5. With these changes, several hundred angle_end2end_tests run without any assertion failures, though still with many test failures. The next crash is in: GLSLTest.NamelessScopedStructs/ES2_Metal and will likely require a larger bug fix, or more changes to be upstreamed from WebKit's repository.

9c6fb52c | 2021-07-13 14:10:41 | Vulkan: SPIR-V Gen: Assignment between mismatching SPIR-V types In general, GLSL qualifiers translate to SPIR-V decorations on SPIR-V variables. In the case of blocks (struct or interface block), OpMemberDecorate is used, which due to its specification in SPIR-V, can only apply decorations to direct members of a block. This makes it impossible for example to decorate a nested member of a block through its variable id. As such, some decorations such as RowMajor and Invariant apply to members of a block given its _type_ id. Unfortunately SPIR-V requires ArrayStride to also be applied to a type directly, rather than a member of a block. This implies that some types, such as structs used in uniform/buffer interface block, or decorated with invariant or row_major, as well as arrays (of any type) used inside and outside interface blocks to produce different SPIR-V types from the same GLSL type. The SpirvTypeSpec data previously introduced specialize these types. It's necessary to "cast" between these types when needed. The translator handles casts at load/store boundary: - Upon load, the value is cast to the type with the default SpirvTypeSpec. - Upon store, the value is cast from the default to the store target SpirvTypeSpec. - All intermediate results use the default SpirvTypeSpec.

5e579a18 | 2021-07-13 01:22:48 | Vulkan: SPIR-V Gen: Support row-major blocks The SPIR-V type generation is refactored to contain all type-differentiating properties in a specific struct that is passed around. The following can lead to different SPIR-V types generated from the same GLSL type: - Block storage for blocks - Invariant for blocks - Row-major for blocks with matrices - Row-major for matrix arrays in blocks - Bool when used inside an interface block (not yet implemented) Previously, block storage and invariant were passed around. Instead, with this change the aggregate of all the above is passed around. The row-major specialization is added in this change. This change also refactors the uniform/buffer block encoding to use the existing encoders in blocklayout.h.

5b314268 | 2021-06-15 17:37:45 | Vulkan: Support OVR_multiview and OVR_multiview2 Multiview is supported in Vulkan simply by specifying the number of views in the render pass, and creating the appropriate image views. A number of changes to the way image views and render targets are stored are made to support those that don't cover the entire range of layers. One particular detail that is not implemented in this change is the use of queries in combination with multiview. Vulkan specifies that N queries are actually produced (N being the number of views) which must be summed by the application, but this is not currently done.

aa2626f9 | 2021-05-21 15:24:55 | Vulkan: SPIR-V Gen: Handle load/store access chain This change implements a key instruction of SPIR-V, OpAccessChain. Inspired by glslang's implementation, a class is added (AccessChain) that tracks "indices" into a base value. These indices could select a field of a block, an element of an array, a column of a matrix, or a component of a vector. Nuances (such as multi-component swizzle as an lvalue not representable in SPIR-V) and optimizations (such as all-literal indices to an rvalue) that are implemented in glslang have also been implemented in this change. As a result, this change implements all manners of loads and stores (with the exception of this gotcha: https://github.com/KhronosGroup/glslang/issues/2637). The change uses this feature to translate the basic shader which does `gl_Position = positionAttr;` (by implementing EOpAssign), and enables a test that uses this shader.

daeac238 | 2021-05-08 22:09:38 | Translator: Ensure structs and blocks are uniquely defined A new AST validation is added to ensure that the same TStructure or TInterfaceBlock is not redundantly defined. This helps with SPIR-V generation by allowing the id to be used as key in a hash map that looks up the corresponding SPIR-V type id. A bug is fixed where the Vulkan driver uniform declaration created two identical declarations for ANGLEDepthRangeParams. A number of other bugs are also fixed in this change, where if a variable declaration is eliminated (for example due to constant folding, or inactive interface variable removal) and it contained a struct specifier, the struct declaration was also removed. OutputGLSLBase had a hack where structs were declared on first encounter, which was incorrect as the scope of the declaration could change. Those bugs are fixed and this hack is removed.

The struct declarations are kept in the AST to be output to GLSL as they normally would when not used in conjunction with uniform variables.
