(insert_pl, extract_pl): New functions. (L2OPT, LS, WC): Use insert_ls and extract_ls. (LS3): New , 3-bit L for sync. (LS3, L3OPT): New, 3-bit L for sync and dcbf. (SC2, PL): New, 2-bit SC and PL for sync and wait. (XWCPL_MASK, XL3RT_MASK, XSYNCLS_MASK): New instruction masks. (XOPL3, XWCPL, XSYNCLS): New opcode macros. (powerpc_opcodes) : New extended mnemonics. : Enable PL operand on POWER10. : Enable L3OPT operand on POWER10. : Enable SC2 operand on POWER10. gas/ * testsuite/gas/ppc/power9.s : Add tests. *
