Revision e21d5ad650130631e17662ce8f22d15315ab597a authored by jsmall-nvidia on 21 November 2018, 18:41:34 UTC, committed by GitHub on 21 November 2018, 18:41:34 UTC
* First pass support for early depth stencil. * Add a simple test to check if output has attributes. * Use cross compilation to test [earlydepthstencil] on glsl. * If target is dxil, use dxc to test against. Add hlsl to test earlydepthstencil against. * * Added spSessionHasCompileTargetSupport * Made slang-test use spSessionHasCompileTargetSupport to ignore tests that cannot run
