GCC maintainers: The following patch adds define_insn support for xxswapd mnemonic. The xxswapd mnemonic is the more prefered name for the xxpermdi mnemonic. The following patch replaces the define_insn xxpermdi with define_insn xxswapd. The patch has been tested on: powerpc64le-unknown-linux-gnu (Power 8 LE) powerpc64le-unknown-linux-gnu (Power 9 LE) with no regressions. Please let me know if the patch is acceptable for trunk.
