I have found out how it can work, even with no change on the GCC side:
Instead of current:
plugin_build_record_type:
record_type = make_node (RECORD_TYPE)
plugin_build_add_field:
add fields to record_type... But there is no
qualified_record_type here!
plugin_finish_record_or_union:
TYPE_SIZE (record_type) etc. ... to finish the type
plugin_build_qualified_type:
qualified_record_type = build_qualified_type (record_type, ...)
one can do instead:
plugin_build_record_type:
record_type = make_node (RECORD_TYPE)
plugin_build_qualified_type:
qualified_record_type = build_qualified_type (record_type, ...)
plugin_build_add_field:
add fields to qualified_record_type
plugin_finish_record_or_union:
TYPE_SIZE (qualified_record_type) etc. ... to finish the type
And one forgets about the unfinished record_type.
For a different cv-quals of the same record type one builds a new cv-qualified
record from scratch.
