Re: [Mesa-dev] [PATCH 1/3] gallium: add explicit return type to texture opcodes

I don't really like this - I'd like to keep d3d10 semantics unless there's a good reason to change it. And I don't see such a reason - even with variable indexing you cannot use mixed int/uint/float textures since texturing results with using the wrong type of sampler are undefined anyway. Hence

[Mesa-dev] [PATCH 1/3] gallium: add explicit return type to texture opcodes

From: Marek Olšák Sampler view declarations have return types, but that doesn't work with variable indexing (e.g. SAMP[-1+i]). Adding the return type to the instruction is simpler. All sampler view declaration flags might have to be removed since variable indexing makes
