We have to check for a fairly pathological case. The operands of function nested function are to be interpreted in the context of the enclosing function. So if any are variably-sized, they will get remapped when the enclosing function is inlined. But that remapping would also have to be done in the types of the PARM_DECLs of the nested function, meaning the argument types of that function will disagree with the arguments in the calls to that function. So we'd either have to make a copy of the nested function corresponding to each time the enclosing function was inlined or add a VIEW_CONVERT_EXPR to each such operand for each call to the nested function. The former is not practical. The latter would still require detecting this case to know when to add the conversions. So, for now at least, we don't inline such an enclosing function. We have to do that check recursively, so here return indicating whether FNDECL has such a nested function. ORIG_FN is the function we were trying to inline to use for checking whether any argument is variably modified by anything in it. It would be better to do this in tree-inline.c so that we could give the appropriate warning for why a function can't be inlined, but that's too late since the nesting structure has already been flattened and adding a flag just to record this fact seems a waste of a flag.
