I don't see how. -fno-merge-constants doesn't say that constants aren't merged within the same TU, they are merged always, -fno-merge-constants is about not allowing constants to be merged between different object files. As without LTO we operate at the level of individual TUs, we don't have issues with that. -fno-merge-constants is the only possible thing on targets that don't have needed support on the assembler/linker side though.
