These generators create two kinds of tests. The first verifies that pre- and post-increment/decrement operations cannot be assignment targets. These look like: uniform float u; varying vec4 v; void main() { float t = u; ++t = float(v.x); gl_FragColor = vec4(t, v.yzw); } The second kind of test verifies that pre- and post-increment/decrement operations cannot be used for function 'out' parameters. These look like: uniform ivec4 u; attribute vec4 v; void f(out ivec4 p) { p = ivec4(v); } void main() { ivec4 t = u; f(t--); gl_Position = vec4(t); } Function 'inout' parameters are not explicitly tested. A test is generated for both vertex and fragment targets for each int and float vector or scalar datatype. Matrix types and GLSL 1.30 unsigned types are not tested.
