avr.c (print_operand): Check that addr is a SYMBOL_REF before using SYMBOL_REF_FLAG (addr).
* config/avr/avr.c (print_operand): Check that addr is a SYMBOL_REF
before using SYMBOL_REF_FLAG (addr).
* config/avr/avr-protos.h (avr_io_address_p): Declare.
* config/avr/avr.c (io_address_p): Rename to avr_io_address_p.
Make non-static. Update all callers.
* config/avr/avr.md (*cbi, *sbi, *sbix_branch, *sbix_branch_bit7):
New insns to clear/set/test a single bit in I/O address space.
