29# Pck.A is an array that embeds elements with variable size so compilers will
30# emit DWARF attributes such as DW_AT_byte_stride to tell GDB how to fetch
31# individual elements.  Array stride is also a way to describe packed arrays:
32# make sure we do not consider Pck.A as a packed array.

35# Make sure this also works with a type from a fully evaluated value.  During
36# evaluation, dynamic types can be "resolved" so GDB internals could "forget"
37# that elements have variable size.  Fortunately, type resolution of array
38# elements happens only when processing individual elements (i.e. the resolved
39# array type is still associated to the dynamic element type), so the following
40# is supposed to work.
