Previously, it didn't matter whether structure splitting tried to split shader ins/outs, because structs were prohibited from being used for shader ins/outs. However, GLSL 3.00 ES supports varying structs. In order for varying structs to work, we need to make sure that structure splitting doesn't get applied to them, because if it does, then the linker won't be able to match up varyings properly. --- src/glsl/opt_structure_splitting.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
