A DWARF array type may specify a stride. Currently, the DWARF reader applies this stride to every dimension of an array. However, this seems incorrect to me -- only the innermost array ought to use the stride, while outer arrays should compute a stride based on the size of the inner arrays. This patch arranges to apply the stride only to the innermost array type. This fixes a bug noticed when running some Ada tests with -fgnat-encodings=minimal. gdb/ChangeLog 2020-11-04 Tom Tromey <tromey@adacore.com> * dwarf2/read.c (read_array_type): Only apply stride to innermost array. gdb/testsuite/ChangeLog 2020-11-04 Tom Tromey <tromey@adacore.com> * gdb.ada/enum_idx_packed.exp: Add test. * gdb.ada/enum_idx_packed/foo.adb (Multi_Access): New variable. * gdb.ada/enum_idx_packed/pck.ads (Short) (Multi_Dimension, Multi_Dimension_Access): New types.
