Zakk Chen 6bb0aa513e [LTO] Suppress emission of empty combined module by default ... Summary: That unless the user requested an output object (--lto-obj-path), the an unused empty combined module is not emitted. This changed is helpful for some target (ex. RISCV-V) which encoded the ABI info in IR module flags (target-abi). Empty unused module has no ABI info so the linker would get the linking error during merging incompatible ABIs.
