    cppgc: young-gen: Support young generation with pointer compression · 6f9df3e7
    Anton Bikineev authored
    Currently, young generation assumes that all the on-heap pointers are
    compressed, which is currently not the case due to the backing-store
    pointers in Blink. Fixing collections to have Member<> is not easy,
    because the inlined collections may have the semantics that
     backing_pointer_ == inlined_buffer_;
    where the inlined_buffer_ can be off-heap (e.g. on stack).
    
    The CL introduces another type of barrier specifically for uncompressed
    pointers. The followup is to use that barrier from Blink.
