Hi all,
I changed the target hook somehow so that more code run in the backend since depending on the target (avr-libc Vs newlib) two different schemes are used: printf -> iprintf renaming or defining _printf_float as a global symbol.
I thus renamed the target hook to match such a usage.
The proposed patch is attached to this email (otherwise it would be mangled).
Joern, would such a scheme be ok for you? You could add another function in targhooks.c for doing the renaming as it could be useful for other targets.
Best regards,
Thomas
