Not in a published patchset
These 7 bundles carry the same evidence an accepted bundle needs: patch variants for every affected release, an executable regression at -O0 and -O2, an explanation with the offending C++ and both Ada outputs, and a coverage panel entry. Patchset 1.2.0 lists them as staged, applies none of them, and makes no claim about their subject.
cxx-ada-concrete-multiple-inheritance
The C++ Ada mapper emits multiple concrete tagged bases as illegal Ada progenitors and omits their secondary subobject storage.
Concrete secondary bases are represented as fixed nested as-base storage rather than native Ada multiple inheritance, so the binding is ABI-faithful but not fully type-safe. Held out of the published patchset for separate upstream review.
cxx-ada-derived-virtual-slots
Class-specific Ada destructor names consume new dispatch slots in derived classes and displace virtual methods introduced after them from their C++ vtable indices.
Stabilizing destructor identities changes generated vtable slot naming for every derived class, which only has an observable contract once the ABI-layout bundles are accepted. Held out of the published patchset for separate upstream review.
cxx-ada-empty-class-storage
The C++ Ada mapper gives complete empty-class objects zero storage and maps overlapping no_unique_address members as ordinary Ada storage.
This patch rewrites needs_tail_padding_layout and reuses the as-base size machinery introduced by the staged tail-padding bundle, and does not apply without it. Held out of the published patchset with the rest of the layout family.
cxx-ada-generated-name-identity
Readable Ada names synthesized for C++ entities can collide with user-written identifiers and with each other.
The name allocator renames the as-base types, synthetic base components, and destructor entities introduced by the staged ABI-layout bundles, and its patch does not apply without them. Held out of the published patchset for separate upstream review.
cxx-ada-inherited-tail-padding
The C++ Ada mapper loses reusable base-class tail padding, including non-polymorphic and multiple-base layouts, so an Ada view can have a larger size and different field offsets than C++.
The nested primary-base component this bundle selects is emitted by the staged virtual-base layout path, so a compiler carrying this patch without the staged ABI-layout bundles does not produce the corrected record. Held out of the published patchset with the rest of the layout family.
cxx-ada-virtual-diamond-layout
The C++ Ada mapper uses complete virtual-base class types for shortened direct base subobjects in a virtual diamond.
Shortened as-base views for diamond legs depend on the virtual-base layout representation and share its C++ ABI coupling. Held out of the published patchset for separate upstream review.
cxx-ada-virtual-inheritance-layout
The C++ Ada mapper drops the size, alignment, and component positions of classes with virtual bases.
Virtual-base layout is C++ ABI-coupled and cannot be expressed as native Ada inheritance; dynamic virtual-base conversion stays an explicit ABI-wrapper boundary. Held out of the published patchset for separate upstream review.
