Vulkan: SPIR-V Gen: Support == and != on complex types In GLSL, == and != produce a bool. In SPIR-V, there are only component-wise comparison operations. For ==, OpAll should be used to reduce it to a single bool, and for !=, OpAny. For matrices, the comparison is done column by column with a similar reduction for each column, and one for the final result. For structs and arrays, the comparison is similarly done field by field or element by element respectively.
