Description
Hi,
DX12 and DX11.3 support optional conservative rasterization.. there are tiers of support and tier3 adds HLSL builtin SV_InnerCoverage..
now that there is a Vulkan extension (VK_EXT_conservative_rasterization) for that and SPIR-V ext SPV_EXT_fragment_fully_covered that adds equivalent new SPIR-V FullyCoveredEXT built in would be nice to have in glslang..
right now only testable by NV Titan V owners..
Contributor guide
Research direction
The issue names no files, tests, or entry points. Start by reviewing glslang's HLSL and SPIR-V support for the conservative-rasterization built-ins, then verify how SV_InnerCoverage should map to FullyCoveredEXT. Done means glslang supports the requested builtin and has coverage for the DX11.3/DX12 and Vulkan/SPIR-V equivalents.
