Tim Van Patten c5c096aa 2019-11-15T15:36:16 Enable Compute Shader Program Input Queries Compute shader inputs were not being tracked in the Shader or Program states, causing program interface queries to fail. This change treats compute shader inputs (all built-ins) as Attributes and pipes them through from the Compiler to the Program to enable input queries. While compute shader inputs are not technically attributes (or varyings), the ANGLE code understands and handles attributes and a program can never have both a vertex and compute shader, so there can't be any conflicts. The naming of these variable lists should probabaly be revisited at some point to better handle these different use-cases.

Shahbaz Youssefi db3e5183 2019-11-14T13:47:55 Vulkan: Fix col-major transformation of unsized arrays If the row-major expression that was being transformed was in the form: arr.length() where `arr` is an SSBO unsized array, the translator transformation was attempting to transpose the `arr` expression, which is both wrong and impossible. Note that length() is removed through a prior transformation except for this particular case. This change recognizes this usage and supports it by keeping the expression as is (as the length() would be identical pre or post transformation).

This will give more correct results on systems that have less than 8 bits of subpixel accuracy. Also uses a more accurate formulation for the emulation filter in the fragment shader using dfdx and dfdy. Fixes line raster CTS tests on SwiftShader. Still does not produce spec conformant lines.

This allows us to support dynamically-uniform array indexing, which is core in ES 3.2. Samplers inside (possibly nested) structs are broken apart as before, and then if the type resulting from merging the array sizes of the field and its containing structs is an array of array, the array is flattened. Also adds an offset parameter to functions taking in arrays to account for this translation. As a result of outer array sizes leaking into function signatures, functions taking arrays of different sizes are duplicated according to how the function is invoked.

Shahbaz Youssefi 93560ef5 2019-07-25T16:13:02 Vulkan: Seamful cube map emulation In GLSL, a cube texture is sampled with one of textureCube* functions. This function takes a 3D coordinate which is a vector from the center of the cube and identifies a direction to sample from. GLES2.0 has the following table that translates this 3D coordinate (Rx, Ry, Rz) to a face and ST coordinates within that face. This table can be found in Section 3.7.5 (Cube Map Texture Selection). A compiler pass is implemented in ANGLE that replaces samplerCube declarations with a sampler2DArray. The textureCube* functions are replaced with the corresponding texture* functions with the translated coordinates according to that table. Gradients provided to textureCubeGrad are translated using the same formulae, which is not precise but the spec specifies this projection to be implementation dependent. Helper invocations enabled through WQM (whole quad mode) cause a nuisance in that the extrapolated varyings used as coordinates in a textureCube call could have a different major axis (and therefore face) from the non-helper invocations that lie within the geometry. subgroupQuadSwap* operations are used in conjunction with gl_HelperInvocation to make sure the helper threads calculate texture UVs in the same face as the non-helper invocations.

Shahbaz Youssefi c13ca2af 2019-07-17T15:46:29 Vulkan: Allow more than one atomic counter buffer binding dEQP assumes there are more than one atomic counter buffers available. This is technically not a requirement by the standard, but nevertheless could be what applications expect as well. This change adds support for multiple atomic counter buffer bindings. This is done by declaring an array of storage buffers for the atomic counter buffers (instead of declaring only one) and passing the (binding, offset) pair around to functions instead of just the offset. The atomic counter is found by indexing `binding` into the storage buffer array first before indexing `offset` into its `uint[]`. ProgramVk's default uniform collection is also fixed not to include atomic counter uniforms. A remaining issue is that atomic counter buffer offsets don't have alignment requirements in GLES, but Vulkan does for storage buffers. Similar to emulated transform feedback buffer offsets, these should be sent to the shader through uniform values. This will be done in a follow up change.

A compiler pass replaces atomic counter definitions with variables that hold the corresponding offset parameter, as well as changing atomic_uint types to just uint (as the offset). Where an atomic counter variable is used, it is replaced with the offset variable (plus the array index, if array).

This trybot runs an analysis pass that checks that any new variable names "kSomthing" is in .rodata or .data.rel.ro because it helps keep the binary size (and the size of each new Chromium process) small on Android. The analysis picks up new usages of StaticType::Helpers::kInstance as a new constant varaible that isn't in .data.rel.ro or .rodata. My understanding is that kInstances isn't put in those segments because it contains a TType that has a "mutable" field so it would be incorrect to put the variable in a read-only segment.

Anders Leino e4452440 2019-05-09T13:29:49 Fix integer cube map sample HLSL calculation This patch fixes two issues in the HLSL generated to sample an integer cube map. The first issue was that an inappropriate major axis was selected when sampling from corners of the cube map. In particular, the added test case demonstrates a situation where a major axis of length 0 was selected, which lead to an infinite LOD being calculated. The fix was to adjust inequalities such that always exactly one of xMajor, yMajor and zMajor is true. The second issue was that the derivative functions ddx and ddy were being used on values that depended on the choice of major axis, which is not continuous at the corners of a cube map. This lead to a finite but incorrect LOD being calculated. The fix was to make sure major axis choice is not included when estimating the scaling factor.
