Inlining has generally been seen as a critical optimization for performance at the cost of size. But, it can also be used for size optimizations in the mobile space. In this talk, we discuss a new inlining technique that explores the full set of inlining candidates to uncover cases where inlining will generate size improvements due to downstream simplifications. It uncovers beneficial inlining that the traditional cost modeling overlooks resulting in non-trivial app size and performance improvements.
