The purpose of this flag is to allow the compiler to assume that each object file passed to the linker has been compiled using a unique source file name. This is useful for reducing link times when doing ThinLTO in combination with whole-program devirtualization or CFI, as it allows modules without exported symbols to be built with ThinLTO.
