	* h8300.h (h8_opcode): Remove 'length' field.
	(h8_opcodes): Mark as 'const' (both the declaration and
	definition).  Modify initializer and initializer macros to no
	longer initialize the length field.

2002-11-11  Klee Dienes  <kdienes@apple.com>

	* h8300-dis.c: Include libiberty.h (for xmalloc).
	(struct h8_instruction): New type, used to wrap h8_opcodes with a
	length field (computed at run-time).
	(h8_instructions): New variable.
	(bfd_h8_disassemble_init): Allocate the storage for
	h8_instructions.  Fill h8_instructions with pointers to the
	appropriate opcode and the correct value for the length field.
	(bfd_h8_disassemble): Iterate through h8_instructions instead of
	h8_opcodes.
