what software relies on the gcc behavior?
software needing -fsemantic-interposition is rare. clang has always been allowing interprocedural optimizations in ELF -fpic mode.
i spotted this in glibc code (which also uses -fgnu89-inline)
but glibc is probably not the only affected software:
in gcc -fsemantic-interposition is the default.
