* config/tc-m88k.c (get_o6): new function.
(get_bf, get_cmp, get_cnd, get_cr, get_fcr, get_imm16, get_reg, get_vec9, getval, get_pcr, calcop, match_name): make static and prototype. (s_file): remove extraneous forward decl. (md_begin): add const to retval decl. (calcop): cope with instructions without arguments. Handle 'o' type argument, the o6 field of the prot insn. (md_estimate_size_before_relax): return a dummy value.

(get_bf, get_cmp, get_cnd, get_cr, get_fcr, get_imm16, get_reg,

get_vec9, getval, get_pcr, calcop, match_name): make static and

* config/m88k-opcode.h (m88k_opcodes): comment change; o6 field is

in bits 10 through 7. flt.[dxs]s requires an r register in the
|

second argument. New instruction lda.x. New instruction muls
