[PATCH for-7.1 v6 24/51] target/nios2: Cleanup set of CR_EXCEPTION for do_interrupt

The register is entirely read-only for software, and we do not implement ECC, so we need not deposit the cause into an existing value; just create a new value from scratch. Furthermore, exception.CAUSE is not written for break exceptions. Signed-off-by: Richard Henderson --- target/nios2/helper
