Supporting Regular and Thin LTO with a Single LTO Bitcode Format - Matthew Voss

—
LTO bitcode files are currently specialized to either Thin or Regular LTO. As a user or middleware library provider, this increases the complexity.

This talk outlines Sony's solution: a single LTO bitcode format that can be used with both Thin and Regular LTO backends.
