The AVR backend now supports conversions between fixed-point numbers and 24-bit integers, addressing missing references during linking. The avr_out_fract function now handles 24-bit integral modes, facilitated by adding PSImode to the mode iterators in avr-fixed.md. This resolves undefined reference errors during linking when using fixed-point conversions with 24-bit integers.
