Without a significant benefits there is not much motivation for developers to adopt it which leads to chicken-egg problem because LTO will not improve without being used and tested. An artiface of this process appears when function calls other functions outside of the comdat section and is the only user of it. Such functions will not be merged.
This infrastructure makes it possible to stream out selected functions and load them into separate compiler that produce code for an accelerator. Constant propagation pass, as name suggest, propagate constant values passed in parameters across the program.
Tentunya ujung-ujungnya adalah untuk penghematan uang. LTO remains more expensive than per-file model especially with compile-edit cycle.

Martin Jambor (SUSE) reorganized the pass to be more modular and allow propagation of various information across the program.
