+ * config/avr/avr.c (avr_mcu_types): Update for new devices.
+ * config/avr/avr.h (TARGET_SWITCHES, AVR_MEGA): Add -mshort-calls.
+ (LINK_SPEC, CRT_BINUTILS_SPECS): Update for new devices.
+ * config/avr/avr.md ("type" and "length" attributes): New type
+ "xcall", length 1 or 2 if AVR_MEGA. Use in all patterns that
+ output a single "call" or "rcall" insn depending on device size.
+ * config/avr/t-avr (MULTILIB_MATCHES): Update for new devices.
