* optabs.h (OTI_flodiv, flodiv_optab): Kill. * genopinit.c: Put floating point divide insns in sdiv_optab. * expr.c (expand_expr): Use sdiv_optab, not flodiv_optab. * config/gofast.h, config/c4x/c4x.h, config/ia64/hpux_longdouble.h, config/mips/mips.h, config/pa/long_double.h, config/rs6000/sysv4.h, config/sparc/sparc.h: Put floating point divide libcalls in sdiv_optab. * optabs.c (init_optab): Break into new_optab, init_optab, init_optabv. (init_optabs): Use init_optabv for overflow-trapping optabs. Don't init flodiv_optab. Give mov_optab, movstrict_optab, and cmp_optab RTX codes so have_insn_for can find them. * optabs.c (expand_simple_binop, expand_simple_unop, have_insn_for, gen_sub3_insn): New interfaces. * expr.h: Prototype new functions. (enum optab_methods): Move here from optabs.h. * builtins.c, combine.c, doloop.c, function.c, ifcvt.c, loop.c, profile.c, simplify-rtx.c, stmt.c, unroll.c: Use new functions instead of working directly with optabs. * doloop.c, ifcvt.c, loop.c, profile.c, simplify-rtx.c, unroll.c: Don't include optabs.h. * caller-save.c, combine.c, function.c, stmt.c: Just include insn-codes.h, not optabs.h. * Makefile.in: Update dependencies. * combine.c (make_compound_operation, simplify_comparison): Fix typos testing for this or that instruction.

There is no negation libcall, and several others have names different

from gcc. This file consolidates the support in one place.

The basic plan is to leave gcc proper alone and via some hook fix things
