I'm curious what the semantics would be for cross-function optimization. For example, consider a function "foo" defined with maxopt and a function "bar" defined with optsize. If foo() calls bar() and the inliner wants to inline bar() into foo(), is that legal? If so, that may cause odd effects as you may perform expensive optimizations later on the inlined version of bar(), even though the original function is marked optsize.<br>

<br></div>Also, a nit-pick: can we make the naming consistent? It feels a bit weird to have maxOPT and OPTsize. Perhaps use sizeopt and minsizeopt, or optmax and optquick?</blockquote></div><br>Meh. I don't care really. It would require changing existing attributes, but we can do that. I think the most readable structure is the first:</div>
