Use more logicals to eliminate useless test/compare instructions
gcc/
* config/h8300/logical.md (<code><mode>3<ccnz>): Use <cczn>
so this pattern can be used for test/compare removal. Pass
current insn to compute_logical_op_length and output_logical_op.
* config/h8300/h8300.c (compute_logical_op_cc): Remove.
(h8300_and_costs): Add argument to compute_logical_op_length.
(output_logical_op): Add new argument. Use it to determine if the
condition codes are used and adjust the output accordingly.
(compute_logical_op_length): Add new argument and update length
computations when condition codes are used.
* config/h8300/h8300-protos.h (compute_logical_op_length): Update
prototype.
(output_logical_op): Likewise.
