When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning: ../accel/tcg/user-exec.c: In function ‘handle_cpu_signal’: ../accel/tcg/user-exec.c:169:13: warning: this statement may fall through [-Wimplicit-fallthrough=] 169 | cpu_exit_tb_from_sighandler(cpu, old_set); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../accel/tcg/user-exec.c:172:9: note: here 172 | default:
This exception branch fall through the 'default' branch and run the 'g_assert_not_reached' statement. So we could use "fall through" instead of "NORETURN" here.
