Currently when lowering mod() we add an extra instruction so if mod(a,b) == b then 0 is returned instead of b, as mathematically mod(a,b) is in the interval [0, b). But Vulkan spec has relaxed this restriction, and allows the result to be in the interval [0, b]. For the OpenGL case, while the spec does not allow this behaviour, due the allowed precision errors we can end up having the same result, so from a practical point of view, this behaviour is allowed (see https://github.com/KhronosGroup/VK-GL-CTS/issues/51). This commit takes this in account to remove the extra instruction required to return 0 instead. Reviewed-by: Daniel Schürmann <daniel@schuermann.dev> Signed-off-by: Juan A.
