Chris Dalton ef9c5ce4 2025-09-07T17:50:37 Add a "noncoherent" layout qualifier to PLS Raster ordering can be expensive. If an app knows the geometry in a draw does not overlap, it can mark the PLS planes as noncoherent and opt for using barriers instead.

Shahbaz Youssefi af0386cb 2025-08-27T10:44:53 Reorder structs entirely made of samplers to the end of struct An earlier change [1] moved samplers to the end of structs so that extracting them does not disturb the indices to the non-sampler fields. This change does the same for structs that only contain samplers, because they too get removed from the parent struct, disturbing indices.

Tom Sepez 25390156 2025-08-21T00:13:19 Suppress unsafe buffers on a file-by-file basis in src/ [1 of N] In this CL, we suppress many files but stop short of actually enabling the warning by not removing the line from the unsafe_buffers_paths.txt file. That will happen in a follow-on CL, along with resolving any stragglers missed here. This is mostly a manual change so as to familiarize myself with the kinds of issues faced by the Angle codebase when applying buffer safety warnings. -- Re-generate affected hashes. -- Clang-format applied to all changed files. -- Add a few missing .reserve() calls to vectors as noticed. -- Fix some mismatches between file names and header comments. -- Be more consistent with header comment format (blank lines and trailing //-only lines when a filename comment adjoins license boilerplate).

This issue was seen on a dEQP test when increasing the LimitToInt() limitation from INT_MAX/2 to INT_MAX+1 or INT_MAX. * Added check to the translator to make sure the offset does not go beyond the max atomic counter buffer size. * Packed the existing checks into a single function. * (checkAtomicCounterOffsetIsValid()) * Added mMaxAtomicCounterBufferSize to TParseContext for the check. * Also added the related cap (maxShaderStorageBlockSize) for D3D11. * Increased the limitation in LimitToInt() to (INT_MAX / 2 + 1). * Added test based on dEQP test that failed on some platforms as a result of updating said limitation. * From KHR-GLES31.core.shader_atomic_counters.negative-large-offset Bug: angleproject:361369308 Change-Id: Id6128c75e12445b2a0029f4a2eb2bdb379cad48d Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/5851650 Commit-Queue: Amirali Abdolrashidi <abdolrashidi@google.com> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
Shahbaz Youssefi 346ba328 2024-07-30T11:42:12 Vulkan: Simplify pulling samplers out of structs The RewriteStructSampler transformation moves samplers out of structs, for example turning this struct: struct Original { sampler2D s1; vec4 f1; sampler2D s2; sampler2D s3; vec4 f2; }; into: struct Modified { vec4 f1; vec4 f2; }; This required modifying the struct-field selection nodes to remap the field indices, causing some complication. Instead, this change makes the struct definition reorder the fields as such right during parse: struct Original { vec4 f1; vec4 f2; sampler2D s1; sampler2D s2; sampler2D s3; }; As a result, the field-selection indices for non-sampler fields don't get changed when the struct is replaced with `Modified`.

EXT_shader_pixel_local_storage explicitly states that all PLS variables consume exactly 4 bytes. ESSL images can only have both read and write access if their format is r32f, r32i, r32ui. (We were able to circumvent this via aliasing, but it was a huge source of bugs.) There is a large precedent for only supporting 4 bytes of storage in the capabilities we use for PLS, so this CL removes support for all PLS storage formats that are not 4 bytes. It also implements an "R32" mode for PLS, that does manual packing and unpacking of r32* image formats. If the application wants larger formats, it can always define multiple PLS planes and piece them together. Next up we ought to be able to support rg16* types with more packing/unpacking. With aliasing gone, and with a bit of tweaking, the PLS tests now pass on the Pixel 4 GLES bot.

Shahbaz Youssefi 6f80f0f0 2022-08-06T02:29:19 Translator: Clean up the compile flag passing interface Historically, compile flags were sent to the translator as a bitmask. Recently, we were getting close to running out of bits. Additionally, direct-to-metal work had started to introduce constants to be passed to the translator, which were misplaced in ShBuiltInResources and Caps. Recent work on Pixel Local Storage adds even more constants, aggravating the situation. In this change, the interface to passing compile flags is reworked. A struct is passed (instead of a bitmask) that has one bit for each flag. This can be indefinitely extended. Additionally, the constants needed by metal and PLS are also placed in this struct. In turn, the backends can set these options directly, and don't have to hack them into Caps to further get hacked into ShBuiltInResources.

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.

A tree traverser is implemented that detects precise access chains and applies precise-ness to the right hand side of assignment expressions to said access chains. This is only done if the shader uses the precise keyword in the first place. The algorithm for this is inspired by the implementation in glslang. This change additionally: - Fixes parser to allow precise on function parameters - Fixes GLSL code generation to output precise on struct members and function parameters.

Also added a few compiler tests to validate the transformation from ESSL to GLSL for Vulkan backend.

Jamie Madill 2c90a90a 2020-12-04T12:39:50 Geometry Shaders: Don't require 'flat' for integer varyings. The 3.2 spec and the dEQP tests are quite clear in only requiring the 'flat' on fragment shader inputs. This restriction remains on older shader versions.

Shahbaz Youssefi abe96578 2020-11-30T14:09:11 Vulkan: I/O blocks: Support unsized arrays Geometry shader inputs have an extra array dimension, which can be unsized as it can be derived from the primitive type. This change fixes the grammar to support such arrays. Additionally, it enables EXT_shader_io_blocks automatically with EXT_geometry_shader and EXT_tessellation_shader per spec.
