2000-06-26 Marek Michalkiewicz <marekm@linux.org.pl>
* avr.h (AVR_ISA_WRAP): Remove, now assumed if not AVR_ISA_MEGA.
(AVR_ISA_ESPM): Remove, because ESPM removed in databook update.
(AVR_ISA_85xx): Remove, all uses changed back to AVR_ISA_2xxx.
(AVR_ISA_M83): Define for ATmega83, ATmega85.
(espm): Remove, because ESPM removed in databook update.
(eicall, eijmp): Move to the end of opcode table.
2000-06-18 Stephane Carrez <stcarrez@worldnet.fr>
* m68hc11.h: New file for support of Motorola 68hc11.
