gallium: add TGSI property NEXT_SHADER
Radeonsi needs to know which shader stage will execute after a shader in order to make the best decision about which shader variant to compile first. This is only set for VS and TES, because we don't need it elsewhere. VS has 3 variants: - next shader is FS - next shader is GS - next shader is TCS TES has 2 variants: - next shader is FS - next shader is GS Currently, radeonsi always assumes the next shader is FS, which is suboptimal, since st/mesa always knows which shader is next if the GLSL program is not a "separate shader". By default, ureg always sets "next shader is FS". Reviewed-by: Nicolai Hähnle <[email protected]>
