  "message": "rs6000: Update existing mma insns to use wD constraint and update %A printer\n\nThis patch replaces the \u0027d\u0027 constraint that was used for accumulators\npreviously since they overlapped with the FPRs, to use \u0027wD\u0027 constraint\nand the new accumulator_operand in the existing mma define_insns. The\nbehaviour without dense-math option will be same as before, only if\ndense-math option is used will the DMR registers be used.\n\nIt also updates the %A operand printer to print the DMR register numbers\ninstead of FPR if dense-math option is enabled\n\n2026-07-16  Avinash Jayakar  \u003cavinashd@linux.ibm.com\u003e\n\t    Vijay Shankar  \u003cvijay@linux.ibm.com\u003e\n\ngcc/ChangeLog:\n\t* config/rs6000/mma.md (mma_xxsetaccz): Use wD constraint and\n\taccumulator operand.\n\t(mma_\u003cvv\u003e): Likewise.\n\t(mma_\u003cavv\u003e): Likewise.\n\t(mma_\u003cpv\u003e): Likewise.\n\t(mma_\u003capv\u003e): Likewise.\n\t(mma_\u003cvvi4i4i8\u003e): Likewise.\n\t(mma_\u003cavvi4i4i8\u003e): Likewise.\n\t(mma_\u003cvvi4i4i2\u003e): Likewise.\n\t(mma_\u003cavvi4i4i2\u003e): Likewise.\n\t(mma_\u003cvvi4i4\u003e): Likewise.\n\t(mma_\u003cavvi4i4\u003e): Likewise.\n\t(mma_\u003cpvi4i2\u003e): Likewise.\n\t(mma_\u003capvi4i2\u003e): Likewise.\n\t(mma_\u003cvvi4i4i4\u003e): Likewise.\n\t(mma_\u003cavvi4i4i4\u003e): Likewise.\n\t* config/rs6000/rs6000.cc (print_operand): Print DMR register\n\tnumbers if dense math option enabled.\n",
