Corentin Noël	1a8dd84ec6	nir: Propagate the type sampler type change to the used variable. ... Avoid keeping a mismatching type between the sampler declaration and its use. In the case of virgl, we were hitting sanity checks when running the spec@arb_fragment_program_shadow@tex-shadow2dnotdepth piglit test.

Illia Polishchuk	0843d4cbc3	nir: switch to a normal sampler for ARB program with not depth textures ... It is undefined behavior when an ARB assembly or shadow2d GLSL func uses SHADOW2D target with a texture in not depth format. In this case AMD and NVIDIA automatically replaces SHADOW sampler with a normal sampler and some games like Penumbra Overture which abuses this UB works fine but breaks with mesa. Replace the shadow sampler with a normal one here by recompiling the ARB program variant Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/8425 Reviewed-by: Emma Anholt <emma@anholt.net> Reviewed-by: Marek Olšák <marek.olsak@amd.com> Signed-off-by: Illia Polishchuk <illia.a.polishchuk@globallogic.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/22147>	2023-05-04 15:43:51 +00:00
