[PATCH] [PR gdb/19820] gdb: allow enumeration constants as second operand of BINOP_REPEAT

This patch adds support for TYPE_CODE_ENUM values to be supplied
as right-hand side operands of the BINOP_REPEAT (@) operator. The
following should now work:
enum {
sz = 17
};
int
main ()
{
int arr[sz + 1] = { 0 };
return 0; /* line 9 here */
}
(gdb) b 9
(gdb) r
(gdb) p arr@sz
$1 = {0 <repeats 17 times>}
(gdb)
A couple of tests is also included in this patch to demonstrate that it is
working as intended.
gdb/Changelog:
2016-03-20 Artemiy Volkov <artemiyv@acm.org>
* eval.c (evaluate_subexp_standard): Allow TYPE_CODE_ENUM to be
the type of BINOP_REPEAT's second operand.
gdb/testsuite/Changelog:
2016-03-20 Artemiy Volkov <artemiyv@acm.org>
* gdb.base/printcmds.exp: Add artificial arrays tests.
