opcodes/ChangeLog
* cr16-dis.c (match_opcode,make_instruction: Remove static declaration. (dwordU,wordU): Moved typedefs to opcode/cr16.h (cr16_words,cr16_allWords,cr16_currInsn): Added prefix 'cr16_' bfd/Changelog * config.bfd (cr16*-*-uclinux*): New target support. include/opcode/ChangeLog * cr16.h (dwordU,wordU): Moved typedefs from cr16-dis.c (make_instruction,match_opcode): Added function prototypes. (cr16_words,cr16_allWords,cr16_currInsn): Declare as extern.
