  "message": "rs6000: Add TDOmode move patterns\n\nAdd move support for the new TDOmode opaque type used to represent\n1024-bit Dense Math Registers that may be supported by future Power\nprocessors.\n\nImplement the movtdo pattern to support moves between memory, VSX\nregisters, and Dense Math Registers. Memory moves and VSX\nregister-to-register moves are handled by the generic multi-register\nsplitter. Dense Math Register-to-Register moves use dmmr, while moves\nbetween VSX and Dense Math Registers are expanded using dm_insert1024\nand dm_extract512.\n\n2026-07-14  Jeevitha Palanisamy  \u003cjeevitha@linux.ibm.com\u003e\n\ngcc/\n\t* config/rs6000/mma.md (UNSPEC_DMF_EXTRACT512): New unspec.\n\t(dm_extract512): New insn.\n\t(movtdo): New expander.\n\t(*movtdo): New insn_and_split to support TDOmode moves between\n\tmemory, VSX registers, and Dense Math Registers.\n\t* config/rs6000/rs6000.cc (rs6000_emit_move): Diagnose constant\n\tassignments to TDOmode objects.\n\t(rs6000_split_multireg_move): Handle TDOmode when splitting\n\tmulti-register moves.\n",
