I wrote a small vertex shader to reproduce this:
in vec4 vertex;
out vec4 color;
uniform vec4 a, b;
void main() {
gl_Position = vertex;
color.xyz = clamp(a.xyz, 0.0, 1.0);
color.w = a.w;
}
Without your patch, we simply drop the saturate in copy propagation. I need to
come up with a way of testing this other than inspecting the disassembly.
I've sent your patch to the mailing list for review. Thanks!
