I don't see any meaningful kind of printf implementation in libiberty. There are implementations of various printf functions in terms of other printf functions (including vprintf in terms of vfprintf in terms of _doprnt in terms of fprintf), but nothing that actually does the main work of converting a floating-point value to a string without calling out to some libc printf function. -- Joseph S.
