- Delete fat library and framework scripts and templates.
- MoltenVK build package now only includes one XCFramework, and separate platform dylibs.
- Modify fetchDependencies and Makefile targets to not build fat libraries,
and to build simulators separately than platforms instead.
- Script package_moltenvk.sh now copies dylibs for all built platforms.
- Consolidate package_all.sh and delete package_one_os.sh.
- Swap names of copy_lib_to_staging.sh and copy_to_staging.sh scripts.
- Cube demo now uses MoltenVK as XCFramework, and support Simulator builds.
- Hologram demo now uses MoltenVK as dylibs from new packaging location.
- API-Samples demo now uses MoltenVK as XCFramework.
- Update documentation.
Create shader converters as XCFrameworks.
Don't create shader converters as fat libs, dylibs, or regular frameworks.
Rename create_xcframework.sh to create_xcframework_func.sh.
Use separate MoltenVK packaging scripts for one or all OS's.
Add package_one_os.sh.
Remove package_shader_converter_lib.sh.
Remove redundant GLSL shader converter dependencies in MoltenVK packaging targets.
Exclude arm64 architectures on macOS and Simulators.
Exclude arm64e architectures on iOS and tvOS.
Stop building fat libraries for external libraries.
Remove package_ext_libs.sh script.
Don't include Headers in ext lib XCFrameworks because of Xcode12 bug in using them.
This should hopefully reduce underutilization of the GPU, especially on
GPUs where the thread execution width is greater than the number of
control points.
This also eliminates the extra invocations previously needed to read the
varyings from the vertex shader into the tessellation shader. The number
of threads per workgroup is now lcm(SIMD-size, output control points).
This should ensure we always process a whole number of patches per
workgroup, and further reduce underutilization of the GPU's SIMD units.
To avoid complexity handling indices in the tessellation control shader,
I've also changed the way vertex shaders for tessellation are handled.
They are now compute kernels using Metal's support for vertex-style
stage input. This lets us always emit vertices into the buffer in order
of vertex shader execution. Now we no longer have to deal with indexing
in the tessellation control shader, nor do we always have to duplicate
the index buffer to insert gaps. This also fixes a long-standing issue
where if an index were greater than the number of vertices to draw, the
vertex shader would wind up writing outside the buffer, and the vertex
would be lost.
Since on macOS textures cannot be resident in shared (host-coherent) memory,
they need to be flushed before making the copy, to ensure that the modified
data is transferred.
fetchDependencies support option to skip all library builds.
fetchDependencies avoid sync locks if not building in parallel.
fetchDependencies build glslang headers.
Update ExternalRevisions/README.md glslang build integration section.
Update What's New.
SPIRV-Cross can now AND the `gl_SampleMask` output with an additional
fixed mask, presumably from the pipeline. Use this new functionality to
implement pipeline sample mask handling.
Special thanks to Tomek Pontika and Corentin Wallez of Google for
graciously contributing their implementation to SPIRV-Cross.
Update SPIRV-Cross to pull in the change necessary for this.
This extension provides weaker guarantees than `VK_EXT_robustness2` and
its `robustImageAccess2` feature. Metal easily meets those guarantees,
with no action on our part necessary.
MVKShaderLibrary::getMTLFunction() synchronize and refactor release of Metal objects.
Make use of existing autorelease pool instead of discrete retain/release.
Wrap entire specialization operation in @synchronized() to guard against
Metal internals not coping with multiple simultaneous specializations.
