Description

This extension adds support for the SPV_AMD_shader_early_and_late_fragment_tests extension, allowing shaders to explicitly opt in to allowing both early and late fragment tests with the EarlyAndLateFragmentTestsAMD execution mode.

If VK_EXT_shader_stencil_export is supported, additional execution modes allowing early depth tests similar to DepthUnchanged, DepthLess, and DepthGreater are provided.
