Consider the following Ada Code:
type Str is new String (1 .. 4);
My_str : Str := "ABCD";
This simply declares a 4-character string type. Trying to perform
equality tests using it currently yield an error:
(gdb) p my_str = my_str
Attempt to compare array with non-array
(gdb) p my_str = "ABCD"
Attempt to compare array with non-array
The error occurs because my_str is defined as an object whose
type is a typdef to a TYPE_CODE_ARRAY, which ada_value_equal
is not expecting at all (yet). This patch fixes this oversight.
gdb/ChangeLog:
* ada-lang.c (ada_value_equal): Add handling of typedef types
when comparing array objects.
gdb/testsuite/ChangeLog:
* gdb.ada/str_binop_equal: New testcase.
Tested on x86_64-linux.
