Split Rendering/LCLD Codec: Unused Symbols

The following symbols (functions) seem to be currently unused in the Split Rendering/LCLD codec:

• ComputeGreedyGroups2() in lib_rend/ivas_RMSEnvGrouping.c
• ComputeGreedyGroups() in lib_rend/ivas_RMSEnvGrouping.c
• QuantizeSpectrumDPCM() in lib_rend/ivas_lcld_encoder.c
• interpolate_gain_matrix() in lib_rend/ivas_splitRendererPost.c
• ivas_split_rend_huffman_code_bits_present() in lib_rend/ivas_splitRendererPost.c
• CreateNoiseGen() in lib_rend\ivas_NoiseGen.c

I'm a bit confused why these symbols seem to show up now as being unused (when building the delivery package), so main question from my side is whether this is on purpose or not. If they are really not used, it would probably be good to remove them.
