Ian Romanick f2ef6036e8 linker: Only over-ride built-ins when a prototype has been seen ... The GLSL spec says: "If a built-in function is redeclared in a shader (i.e., a prototype is visible) before a call to it, then the linker will only attempt to resolve that call within the set of shaders that are linked with it." This patch enforces this behavior. When a function call is processed a flag is set in the ir_call to indicate whether the previously seen prototype is the built-in or not. At link time a call will only bind to an instance of a function that matches the "want built-in" setting in the ir_call. This has the odd side effect that first call to abs() in the shader below will call the built-in and the second will not: float foo(float x) { return abs(x); } float abs(float x) { return -x; } float bar(float x) { return abs(x); } This seems insane, but it matches what the spec says.
