* ppc-opc.c (powerpc_operands): New operand type MBE to handle a
single number giving a bitmask for the MB and ME fields of an M form instruction. Change NB to accept 32, and turn it into 0; also turn 0 into 32 when disassembling. Seperated SH from NB. (insert_mbe, extract_mbe): New functions. (insert_nb, extract_nb): New functions. (SC_MASK): Mask out SA and LK bits. (powerpc_opcodes): Change "cal" to use RT, D, RA rather than RT, RA, SI. Change "liu" and "cau" to use UI rather than SI. Mark "bctr" and "bctrl" as accepted by POWER. Change "rlwimi", "rlimi", "rlwimi.", "rlimi.", "rlwinm", "rlinm", "rlwinm.", "rlinm.", "rlmi", "rlmi.", "rlwnm", "rlnm", "rlwnm.", "rlnm." to use MBE rather than MB. Add "mfmq" and "mtmq" POWER instructions. (powerpc_macros): Define table of macro definitions. (powerpc_num_macros): Define.
