[gcc] 2017-11-10 Michael Meissner <meissner@linux.vnet.ibm.com> * config/rs6000/rs6000.md (bswaphi2_reg): On ISA 3.0 systems, enable generating XXBRH if the value is in a vector register. (bswapsi2_reg): On ISA 3.0 systems, enable generating XXBRW if the value is in a vector register. (bswapdi2_reg): On ISA 3.0 systems, always use XXBRD to do register to register bswap64's instead of doing the GPR sequence used on previous machines. (bswapdi2_xxbrd): New insn. (bswapdi2_reg): Disallow on ISA 3.0. (register to register bswap64 splitter): Do not split the insn on ISA 3.0 systems that use XXBRD. [gcc/testsuite] 2017-11-10 Michael Meissner <meissner@linux.vnet.ibm.com> * gcc.target/powerpc/p9-xxbr-3.c: New test. From-SVN: r254643
