The DECL_DECLARED_INLINE_P test is what > matters. So, IIUC, it is perfectly reasonable to make these optimisations if (a) we completely inline the callee or (b) we clone the callee. If the only case in which we need to back out of (or disable) the optimisation is when we determine that we are not going to take either of those actions, but the callee is DECL_DECLARED_INLINE_P - then how often would we be losing a "useful (albeit potentially invalid) optimisation" ?
