ubsan: z8k: index 10 out of bounds for type 'unsigned int const[10]'
The fix is the additional ARRAY_SIZE test, the rest just tidies
variable types rather than adding a cast to avoid warnings.
opcodes/
* z8k-dis.c: Include libiberty.h
(instr_data_s): Make max_fetched unsigned.
(z8k_lookup_instr): Make nibl_index and tabl_index unsigned.
Don't exceed byte_info bounds.
(output_instr): Make num_bytes unsigned.
(unpack_instr): Likewise for nibl_count and loop.
* z8kgen.c (gas <opcode_entry_type>): Make noperands, length and
idx unsigned.
* z8k-opc.h: Regenerate.
gas/
* config/tc-z8k.c (md_begin): Make idx unsigned.
(get_specific): Likewise for this_index.
