Testing with -fgnat-encodings=minimal showed that the Ada code failed to use the bit stride of an array when taking a slice. This patch fixes the oversight. gdb/ChangeLog 2020-11-04 Tom Tromey <tromey@adacore.com> * ada-lang.c (ada_value_slice_from_ptr): Use bit size. gdb/testsuite/ChangeLog 2020-11-04 Tom Tromey <tromey@adacore.com> * gdb.ada/array_of_variant.exp: New file. * gdb.ada/array_of_variant/p.adb: New file. * gdb.ada/array_of_variant/pck.ads: New file. * gdb.ada/array_of_variant/pck.adb: New file.
