[Mesa-dev] [PATCH 00/22] Enable Float64 capability support for Intel's Vulkan driver

[Juan A. Suarez Romero]

Hello,

This patch series implements support for Float64 capability to SPIR-V to NIR
pass and adds the needed bits to enable it in Intel's Vulkan driver. Float64
capability is only enabled in Intel's generations that support
ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit (currently Broadwell and newer),
follow-up patches will be sent once ARB_gpu_shader_fp64 and
ARB_vertex_attrib_64bit support for other generations (Haswell and Ivybridge) is
in master.

We have tested these patches against Vulkan conformance test suite [0]. All the
Float64 tests pass, except the ones that also requires other unsupported
capabilities. The results we got running VulkanCTS on master with and without
these patches are:
