--- Comment #3 from Roland Scheidegger <[email protected]> ---
Here's a simplified example, not even the empty branch is necessary, it is
sufficient if the return is inside a loop which is inside a conditional (I'm
actually wondering why this isn't hit in ordinary shaders...):
#version 130
uniform vec2 val_cond;
float func1()
{
if(val_cond.x > val_cond.y) {
for(int i = 0; i < 1; i++) {
return 2.0;
}
}
return 1.0;
}
void main(void)
{
gl_FragColor = vec4(func1());
}
The --dump-lir output for func1 is just:
( function func1
(signature float
(parameters
)
(
(return (constant float (1.000000)) )
))
)
