    third_party/clspv: Update CLSPV(#1423)

The clspv is rebased to the below commit to fix
test_vectors vec_align_struct with
the spir64/phy_addressing option

- 60f822e8 fix LongVectorLoweringPass
when removing dead long-vector globals
that were lowered. (#1423)

As part of that clspv rebase, llvm is rebased
to the version used by clspv

- 1fd8d3fea53e (HEAD) [mlir] Fix wrong names
in LinalgOps and ScalableValueBoundsConstraintSet
(#117227)

The rebase of LLVM required updates
to the GN build files in clspv,
appropriate changes are made.

* .bc files are pre-builts and they are deviations
from upstream. Update of gn files for libclc will
be followed in separate patch.

  • ANGLE - Almost Native Graphics Layer Engine

    The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0, 3.0 and 3.1 to Vulkan, desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Future plans include ES 3.2, translation to Metal and MacOS, Chrome OS, and Fuchsia support.

    Level of OpenGL ES support via backing renderers

    Direct3D 9 Direct3D 11 Desktop GL GL ES Vulkan Metal
    OpenGL ES 2.0 complete complete complete complete complete complete
    OpenGL ES 3.0 complete complete complete complete complete
    OpenGL ES 3.1 incomplete complete complete complete
    OpenGL ES 3.2 in progress in progress complete

    Additionally, OpenGL ES 1.1 is implemented in the front-end using OpenGL ES 3.0 features. This version of the specification is thus supported on all platforms specified above that support OpenGL ES 3.0 with known issues.

    Platform support via backing renderers

    Direct3D 9 Direct3D 11 Desktop GL GL ES Vulkan Metal
    Windows complete complete complete complete complete
    Linux complete complete
    Mac OS X complete complete [1]
    iOS complete [2]
    Chrome OS complete planned
    Android complete complete
    GGP (Stadia) complete
    Fuchsia complete

    [1] Metal is supported on macOS 10.14+

    [2] Metal is supported on iOS 12+

    ANGLE v1.0.772 was certified compliant by passing the OpenGL ES 2.0.3 conformance tests in October 2011.

    ANGLE has received the following certifications with the Vulkan backend:

    • OpenGL ES 2.0: ANGLE 2.1.0.d46e2fb1e341 (Nov, 2019)
    • OpenGL ES 3.0: ANGLE 2.1.0.f18ff947360d (Feb, 2020)
    • OpenGL ES 3.1: ANGLE 2.1.0.f5dace0f1e57 (Jul, 2020)
    • OpenGL ES 3.2: ANGLE 2.1.2.21688.59f158c1695f (Sept, 2023)

    ANGLE also provides an implementation of the EGL 1.5 specification.

    ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

    Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Vulkan GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.

    OpenCL Implementation

    In addition to OpenGL ES, ANGLE also provides an optional OpenCL runtime built into the same output GLES lib.

    This work/effort is currently work-in-progress/experimental.

    This work provides the same benefits as the OpenGL implementation, having OpenCL APIs be translated to other HW-supported APIs available on that platform.

    Level of OpenCL support via backing renderers

    Vulkan OpenCL
    OpenCL 1.0 in progress in progress
    OpenCL 1.1 in progress in progress
    OpenCL 1.2 in progress in progress
    OpenCL 3.0 in progress in progress

    Each supported backing renderer above ends up being an OpenCL Platform for the user to choose from.

    The OpenCL backend is a “passthrough” implementation which does not perform any API translation at all, instead forwarding API calls to other OpenCL driver(s)/implementation(s).

    OpenCL also has an online compiler component to it that is used to compile OpenCL C source code at runtime (similarly to GLES and GLSL). Depending on the chosen backend(s), compiler implementations may vary. Below is a list of renderers and what OpenCL C compiler implementation is used for each:

    • Vulkan : clspv
    • OpenCL : Compiler is part of the native driver
