(Ada) Remove printing of array's first index when unneeded
Consider the following code:
type Table is array (Character) of Natural;
My_Table : Table := (others => 4874);
Printing this table in gdb leads to:
(gdb) p my_table
$1 = ('["00"]' => 4874 <repeats 256 times>)
In this case, the index of the first element in this array is also
the first element of the index type (character type). Similar to what
we do we enumeration types, we do not need to print the index of the
first element when printing the array.
This patch fixes this issue and changes the output as follow:
(gdb) p my_table
$1 = (4874 <repeats 256 times>)
gdb/ChangeLog:
* ada-valprint.c (print_optional_low_bound): Handle
character-indexed array printing like boolean-indexed array
printing.
gdb/testuite/ChangeLog:
* testsuite/gdb.ada/array_char_idx/pck.ads (Table): New type.
(My_Table): New global variable.
* testsuite/gdb.ada/array_char_idx.exp: Add test.
Tested on x86_64-linux.
