Inlining pros and cons (discussion). Inlining pros and cons. Pros eliminate overhead of call/return sequence eliminate overhead of passing args & returning results can optimize callee in context of caller and vice versa Cons can increase compiled code space requirements

Inlining. Replace call with body of callee Turn parameter- and result-passing into assignments do copy prop to eliminate copies Manage variable scoping correctly rename variables where appropriate. Call graph nodes are procedures edges are calls, labelled by invocation counts/frequency

From last time: Inlining pros and cons

From last time: Inlining pros and cons. Pros eliminate overhead of call/return sequence eliminate overhead of passing args & returning results can optimize callee in context of caller and vice versa Cons can increase compiled code space requirements can slow down compilation recursion?

Cost Models

Cost Models. Which Is Faster?. Every experienced programmer has a cost model of the language: a mental model of the relative costs of various operations Not usually a part of a language specification, but very important in practice. val y = 1::x; val y = append(1,x);. Outline.
