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

37# Make sure this also works with a type from a fully evaluated value.  During
38# evaluation, dynamic types can be "resolved" so GDB internals could "forget"

40# elements happens only when processing individual elements (i.e. the resolved
41# array type is still associated to the dynamic element type), so the following
