Looks good!

Please break this line, if you can:

1099   call = make_leaf_call(c, m, ShenandoahBarrierSetC2::shenandoah_clone_barrier_Type(),
CAST_FROM_FN_PTR(address, ShenandoahRuntime::shenandoah_clone_barrier), "shenandoah_clone_barrier",
raw_adr_type, dest->in(AddPNode::Base));


We should probably stop calling it "g1_wb_pre" pretty soon:

 465         __ make_leaf_call(tf, CAST_FROM_FN_PTR(address,
ShenandoahRuntime::write_ref_field_pre_entry), "g1_wb_pre", pre_val, tls);
