Shahbaz Youssefi 3b65b803 2022-04-27T11:04:22 Vulkan: Work around Qualcomm imprecision with dithering On qualcomm, sometimes the output is ceil()ed instead of round()ed. With ditering emulation affecting values, some dEQP tests fail due to the excessive change in value when dithering bumps the value slightly over to the next quantum. In this change, a workaround is added to round() the value before outputting it.

Shahbaz Youssefi c5271e8e 2022-04-04T23:28:35 Vulkan: Emulate GL_KHR_blend_equation_advanced Based on a change by Brandon Schade <b.schade@samsung.com> In the translator, when advanced blend is enabled, an input attachment is added. Based on the listed advanced blend equations, emulation code is added that performs those equations' functions. The blend equation itself is passed through a driver uniform. Note that the advanced blend extension only allows a single output to use advanced blend, and that should be at location 0. In the Vulkan backend, when advanced blend is used, the driver uniform to select the equation is updated and normal blending is disabled.

Shahbaz Youssefi 665ddccd 2021-12-09T23:06:39 Vulkan: Emulate dithering Dithering in OpenGL is vaguely defined, to the extent that no dithering is also a valid dithering algorithm. Dithering is enabled by default, but emulating it has a non-negligible cost. Similarly to some other GLES drivers, ANGLE enables dithering only on low-bit formats where visual banding is particularly common; namely RGBA4444, RGBA5551 and RGB565. Dithering is emulated in the fragment shader and is controlled by a spec constant. Every 2 bits of the spec constant correspond to one attachment, with the value indicating: - 00: No dithering - 01: Dither for RGBA4444 - 10: Dither for RGBA5551 - 11: Dither for RGB565 The translator appends code to the shader that, based on the format specified by the specialization constant, adds dithering to each color attachment output. A 2x2 Bayer matrix is used for dithering, indexed by gl_FragCoord.xy % 2.

Shahbaz Youssefi 0f00fbae 2022-01-21T00:28:48 Translator: Make vec/matrix size getters unsigned TType stored type's primary and secondary sizes as `unsigned char`, but the getters returned `int`. This caused unnecessary casts when the size was passed from one TType to another, as well as comparisons with other unsigned numbers. This change specifies the type of these members as `uint8_t` and makes the getters return the same type. The call sites are accordingly adjusted to remove unnecessary casts, use the correct type in local variables, and add casts when passed to ostream::operator<<.

Shahbaz Youssefi 800e82c6 2021-08-23T11:05:23 Translator: Validate precisions When declaring a variable, a struct field, function parameter etc, there's a precision necessarily applied to the entity being declared. AST Validation is added to enforce this. Intermediate nodes derive their precision from these entities automatically. Consistency of intermediate nodes is not validated. This is because AST transformations replace a node with a transformed one, and that may not have the same precision. Take the following code: mediump float x = ...; mediump float y = ...; ... x + y ... and assume is transformed as such: highp float driver_uniform; ... (x * driver_uniform) + y ... The addition was originally done in mediump, but would seemingly need to be done in highp after transformation. There are a number of options here: - Make sure that when nodes are replaced, the precision is unaffected. This can be intrusive, requiring temp variables. - Bubble up the new precision - Accept the discrepancy ANGLE opts for the last option, which actually respects the original shader's intended precision for operations, even if some transformation needs to temporarily evaluate an expression at a higher precision.

This was due to the fact that visitBlock() was asking traversal to continue if a new case was visited while pruning nodes, but the traversal does not take into account that some statements need to be skipped and so would also visit the pruned statements. If the pruned statements contain a branch instruction, they get re-pruned. The visitBlock() function that does the pruning is reworked so that it more clearly traverses the statements.

Shahbaz Youssefi ebe943e2 2021-07-29T11:19:33 Vulkan: SPIR-V Gen: Fix gl_Clip/CullDistance These built-ins can be redeclared in the shader. The translator took these redeclarations (and gl_LastFragData) as UserDefined symbols. There were a number of hacks such as in name generation and CollectVariables, to special-case these redeclarations. This change instead makes sure that these variables continue to be considered built-ins with the appropriate qualifiers. A number of fixes are made accordingly: - Hacks are removed. - In fragment shaders, ANGLEClipDistance was initialized with gl_ClipDistance for further use by the shader. The code generation however mistakenly produced `gl_ClipDistance[0] = ANGLEClipDistance[0];`, which caused compilation failures by glslang, but passed the tests accidentally because they expected link failures (see next item). - CollectVariables is fixed to correctly collect gl_Clip/CullDistance in fragment shaders; previously they were collected as output varyings, and therefore the aforementioned link error was not produced in the tests after the compilation error was fixed. Additional fixes: - The transformation of gl_Clip/CullDistance was always ever done on one of them due to misplaced breaks in the loop that detected their presence. - The transformation of gl_CullDistance was skipped when it was not redeclared. Validation is added to make sure these built-ins always have the correct qualifier even when redeclared. SPIR-V gen support for these variables have been fixed as well.

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.

Shahbaz Youssefi 60015ff6 2021-01-14T02:03:07 Vulkan: Redo RewriteStructSamplers This transformation is split into two. The first transformation solely takes out the samplers out of structs, and potentially generates array of array of samplers. A second transformation is added that takes any array of array of opaque uniforms and flattens it. A follow up change will simplify RewriteAtomicCounters which also handles array of arrays (which is no longer possible), and removes dependency on shaderStorageBufferArrayDynamicIndexing.

Shahbaz Youssefi dc99fc40 2021-01-13T00:21:41 Vulkan: Translator pass to monomorphize problematic functions With array of array of samplers and images, we currently require the shader*ArrayDynamicIndexing Vulkan features. With atomic counters, we require the shaderStorageBufferArrayDynamicIndexing feature. The above features are required to enable passing opaque uniforms to functions. This change introduces a translator pass that monomorphizes functions that receive atomic counters, or partially subscripted array of array of samplers or images, etc by removing those arguments and using the opaque uniform directly. Follow up changes will include: - Great simplification to RewriteStructSamplers, and removal of RewriteStructSamplersOld. This will drop dependency to shaderSampledImageArrayDynamicIndexing and shaderStorageImageArrayDynamicIndexing. - Great simplification to RewriteAtomicCounters. This will drop dependency to shaderStorageBufferArrayDynamicIndexing. - Emulation of imageAtomicExchange for r32f formats, but changing the qualifier to r32ui. Note that parts of RewriteStructSampler are obsolete with this change, but will be refactored as a follow up.

Shahbaz Youssefi 382bf288 2020-12-24T23:56:39 Organize AST transforms per backend Most of the AST transforms are written as a workaround to an issue that affects a single backend. This change identifies such transforms and organizes them by backend. They are then only built if the respective backend is. Additionally, about half of the GL transforms are due to mac workarounds, including the large RewriteRowMajorMatrices transform. Mac-specific workarounds are additionally only built on said platform. This change reduces the ANGLE binary size: - 106KB in a Vulkan-only build on Linux - 27KB in a GL-only build on Android (60KB on Linux) Bug: chromium:1084580 Bug: chromium:1161513 Change-Id: I64b334332c0d4f848756c6538af0d8d96864c7e9 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2601346 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tim Van Patten <timvp@google.com>
