Re: [RFC/Ada 1/2] Add command to list Ada exceptions

>>>>> "Joel" == Joel Brobecker <> writes:

Since the name of the command is unavoidably generic, how about adding
"Ada" into the output somewhere, so that non-Ada users don't get
confused when the command doesn't do anything useful for them?


    (gdb) info exceptions
    All defined Ada exceptions:
    constraint_error: 0x613dc0

Joel> +  for (i = 0; i < sizeof (standard_exc) / sizeof (char *); i++)

How about ARRAY_SIZE here?

The current style requires a "!= NULL" here.

I think regexp can be const.

Joel> +      preg = alloca (sizeof (regex_t));

Joel> +	}
Joel> +      make_regfree_cleanup (preg);
Joel> +    }

These days there is compile_rx_or_error, which wraps all this up.

Joel> +  printf_filtered (regexp
Joel> +		   ? "All exceptions matching regular expression \"%s\":\n"
Joel> +		   : "All defined exceptions:\n", regexp);

This needs an explicit "== NULL".
