The rs6000 backend now includes new define_insn_and_split patterns for handling TDOmode reloads between Dense Math Registers (DMRs) and memory. These patterns are activated when TARGET_DMF is enabled, allowing the compiler to efficiently manage data transfers for TDOmode values involving DMRs and memory.
