TODO Dex2oat - ART’s Multi-Purpose On-Device Compiler

• multi purpose: compile apps, system services, boot.oat
• reason: efficiency: battery, computation
• flexible: different backends with IRs, per-architecture code generators
• just a binary with libraries
• state of the art optimizations
• multiple modes: from jitting to full compilation (enforced with ARTist)
• optimizing backend: default since 6, clean single IR
• one method at a time, no hollistic view

• we exploit the optimization framework by adding own “passes”

• details about IR!!! Reference from making module to here
