* 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.
