Added following updates to GL_EXT_mesh_shader implementation:
1. Added SPIRV and GLSL test cases
2. Added checks to ensure NV and EXT mesh shader builtins cannot be used interchangeably.
3. Updated the language name by removing the postfix "NV" to MeshShader and TaskShader.
4. Added checks for grammar checking to comply with the spec.
5. Added gl_NumWorkGroups builtin to Mesh shader
6. Fixed data type of gl_PrimitiveLineIndicesEXT and gl_PrimitiveTriangleIndicesEXT
7. Added new constants to the resources table
8. Updates to handle new storage qualifier "taskPayloadSharedEXT"
9. Updated test cases by replacing "taskEXT" with storage qualifier "taskPayloadSharedEXT"
Addressed Review comments
1. Fixed instruction description used by glslang disassembly.
2. Updated OpEmitMeshTasksEXT as per spec update
3. Fixed implementation that errors out if there are more then one taskPayloadSharedEXT varjables.
4. Fixed miscellaneous error logs and removed unwanted code.
SPIRV 1.6 related build failure fixes
- Update SPIRV header to 1.6
- Fix conflict wiht SPIRV 1.6 change, where localSizeId is used for execution mode for mesh/task shaders
Enable SPIRV generated for EXT_mesh_shader to be version 1.4
GL_EXT_mesh_shader: Add checks for atomic support and corresponding test cases
Also update known goods to Vulkan 1.3 support
Also re-enable SPIR-V 1.6 tests with vulkan1.3 target
Also re-cache SPIRV 1.6 header which somehow regressed back to 1.5
Add command line support which enables the following behavior:
- Remap discard
Map discard to DemoteToHelperInvocation for HLSL shaders. Map to
OpTerminateInvocation for GLSL shaders.
- Decorate HelperInvocation with Volatile
- Use localSizeId for execution mode
WorkGroupSize is deprecated in spirv1.6
Also update known goods to SPIRV 1.6
Generate load of interpolant for first operand to GLSLstd450
InterpolateAt* SPIR-V ops. This allows the interpolants to
propagate from the input struct in the wrapper around main
into the shader during HLSL legalization. A new pass has been
added to legalization which will remove the load and replace
with the pointer of the load to create valid external
interpolate op.
Fixes#2584
