Fix handling of typedefs to types having a data_location attribute.
Consider an array described in the debugging information as being
a typedef of an array type for which there is a DW_AT_data_location
attribute. Trying to print the value of that array currently yields
incorrect element values. For instance:
(gdb) print foo.three_tdef
$1 = (6293760, 0, 6293772)
The problem occurs because we check for the data_location attribute
only on the typedef type, whereas we should be checking for the
typedef's target type. As a result, GDB erroneously thinks that
there is no data_location, and therefore starts reading the array's
content from the address of the descriptor instead of the data_location
address.
gdb/ChangeLog:
* value.c (value_from_contents_and_address): Strip resolved_type's
typedef layers before checking its TYPE_DATA_LOCATION.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/data-loc.exp: Add additional tests exercising
the handling of variables declared as a typedef to an array
which a DW_AT_data_location attribute.
