To support the duality concrete/abstract instance of static data
member variables in DWARF, the reader needed a little bit of an
overhaul. That overhaul is necessary to self-compare libLLVM.so, from
llvm-libs, in fc37. Note that that self-compare is done using this
command:
$ fedabipkgdiff -a--self-compare --from fc37 llvm-libs
So now, with this patch, the IR of a static data member is constructed
only when the concrete instance DIE of the static data member is
encountered. The abstract instance DIE is then read first, the IR is
built from it, and then the concrete instance DIE is read for
additional attributes that might be needed, like the ELF symbol
attribute.
The patch fixes a number of issues related to static data members
representation in the IR, namely, it puts them all in their own array
in the class_or_union, just like what is done for non-static data
members. The ABIXML writer is updated to emit static data member from
their new storage.
* include/abg-ir.h (class_or_union::get_static_data_members):
Declare new method.
* src/abg-dwarf-reader.cc (add_or_update_class_type): Do not
create any IR for the /declaration/ of static data member here.
Wait for its definition from a concrete instance DIE to create the
IR for it.
(build_ir_node_from_die): In the DW_TAG_variable case, if we are
looking at the concrete instance of a static variable (one that
has a DW_AT_abstract_origin pointing to a static data member) then
build the IR from it and add it to its class scope.
* src/abg-ir-priv.h (class_or_union::priv::static_data_members_):
Define new data member.
(class_or_union::priv::priv): Stick the static data members that
are in class_or_union::priv::data_members_ into
class_or_union::priv::static_data_members_.
* src/abg-ir.cc (maybe_adjust_canonical_type): Make sure static
data members of the canonical type has the same symbols set as the
data members of the canonicalized type.
(class_or_union::add_data_member): Update the new
class_or_union::priv::static_data_members_ when a data member is
added.
(class_or_union::get_non_static_data_members): Fix comments.
(class_or_union::get_static_data_members): Define new member
functions.
(set_member_is_static): Update the new
class_or_union::priv::static_data_members_ when static-ness is
changed.
* src/abg-writer.cc (write_decl_in_scope): Support writing pure
declarations (not types).
(write_translation_unit): Don't forget to write remaining global
variables.
(write_class_decl): Make sure to write static data members first,
before writing the non-static data members.
