Tom Tromey 6c71eb7d70 Normalize Ada ptype to use a single "?" ... Sometimes -- notably with unchecked unions -- the Ada "ptype" code will print a "?" or "??" to indicate something unknown. The choice of what was printed was somewhat arbitrary, and in one case, Ada would print an empty string rather than "?". This patch normalizes the Ada code to use "?" rather than an empty string or "??". My reasoning here is that a single question mark is enough to convey unknown-ness. gdb/ChangeLog 2019-12-10 Tom Tromey <tromey@adacore.com> * ada-typeprint.c (print_choices): Use a single "?". (print_variant_part): Print "?" if the discriminant name is not known. gdb/testsuite/ChangeLog 2019-12-10 Tom Tromey <tromey@adacore.com> * gdb.ada/unchecked_union.exp: New file. * gdb.ada/unchecked_union/pck.adb: New file. * gdb.ada/unchecked_union/pck.ads: New file. * gdb.ada/unchecked_union/unchecked_union.adb: New file. * gdb-utils.exp (string_to_regexp): Also quote "?".
