Fix gdb.ada/vla.exp
PR ada/24539 concerns a test failure in gdb.ada/vla.exp. The problem here is that different versions of Gnat emit the structure's fields in different orders -- with the order currently failing actually being the correct one. Joel pointed out that this can be fixed by simply adding the No_Component_Reordering pragma to the type in question, which is what this patch does. I've reported a Gnat compiler bug internally in hopes of getting the underlying problem fixed. gdb/testsuite/ChangeLog 2019-06-14 Tom Tromey <tromey@adacore.com> PR ada/24539: * gdb.ada/vla.exp: Update tests. * gdb.ada/vla/vla.adb (Record_Type): Use No_Component_Reordering pragma.
