It is the
-flto, once I remove it, it links fine. Also when I compile __aeabi_d2f.c alone into separate .o but without -flto it works when the rest uses -flto. However when I add -flto to that separate compile into __aeabi_d2f.o it does not help and does not work.So somehow gcc expects the
__aeabi_d2fto be placed in object file which is not compiled with lto.
