LTO in Android refers to LINK Time Optimization, a compilation technique that optimizes code across different compilation units. It's used to improve performance and reduce the size of the final binary by eliminating redundant code and performing other optimizations during the linking stage.

LLVM's Control Flow Integrity (CFI) feature enhances program security by ensuring that indirect control transfers only occur at authorized points. This mechanism requires a specific compilation process to fully leverage its benefits.

One crucial aspect of implementing LLVM's CFI is the utilization of Link-Time Optimization (LTO). LTO is a compilation technique that delays the final linking phase until all object files have been generated, allowing for more comprehensive optimizations across the entire program.

During LTO, LLVM maintains the bitcode representation of object files until the linking stage. This approach is advantageous as it provides the compiler with a more holistic view of the program's structure and behavior.

With access to the bitcode representation, the compiler can make more informed decisions about which optimizations to apply. For instance, it can identify patterns that would otherwise be missed during traditional, separate compilation and linking processes.

The use of LTO in conjunction with LLVM's CFI enables the compiler to optimize the program while simultaneously enforcing stricter control Flow constraints. This combination strengthens both the program's security and performance.
