Add support for displaying structures and bitfields for registers when
executing "maint print c-tdesc". This command is also used when
converting the xml target description file into c file.
Example of the behaviour is given below reporting a snipet of the xml file
and a snippet of the c code generated.
XML file contains:
...
<union id="vecint">
<field name="v4" type="v4int8"/>
<field name="v2" type="v2int16"/>
</union>
<struct id="struct1">
<field name="v4" type="v4int8"/>
<field name="v2" type="v2int16"/>
</struct>
<struct id="struct2" size="8">
<field name="f1" start="0" end="34"/>
<field name="f2" start="63" end="63"/>
</struct>
...
Setting this xml file as target description file and
issuing the maintenance print c-tdesc the following output
is obtained:
feature = tdesc_create_feature (result, "extra");
field_type = tdesc_named_type (feature, "int8");
tdesc_create_vector (feature, "v4int8", field_type, 4);
field_type = tdesc_named_type (feature, "int16");
tdesc_create_vector (feature, "v2int16", field_type, 2);
type = tdesc_create_union (feature, "vecint");
field_type = tdesc_named_type (feature, "v4int8");
tdesc_add_field (type, "v4", field_type);
field_type = tdesc_named_type (feature, "v2int16");
tdesc_add_field (type, "v2", field_type);
C output is not supported type "struct1".
This is finally the issue.
