Don't know.

Was fixed by:
2001-03-28  Marek Michalkiewicz  <address@hidden>

        * config/avr/libgcc.S (__mulhi3): Correct tests to exit the loop
        when multiplier or multiplicand is zero.

> C: Has no (known) O3 bugs

It's really a conditional jump bug.
Was fixed by:
Sun Jan 21 09:44:17 2001  Denis Chertykov  <address@hidden>

        * config/avr/avr.c (ret_cond_branch): New argument (reverse) added.
        If REVERSE nonzero then condition code in X must be reversed.
        (encode_section_info): Optimise if/else.
        (avr_function_value): Fix formatting.

        * config/avr/avr.md (branch): Call to ret_cond_branch changed.
        (difficult_branch): Likewise.
        (rvbranch): Likewise.
        (difficult_rvbranch): Likewise.

        * config/avr/avr-protos.h (ret_cond_branch): Prototype changed.

        * config/avr/libgcc.S: Fix comment.

> D: Has no (major) known other bugs

I don't know.
