real: Do not include gmp.h, mpfr.h, and mpc.h.
gcc/ChangeLog: * real: Do not include gmp.h, mpfr.h, and mpc.h. (REAL_VALUE_NEGATE, REAL_VALUE_ABS, real_arithmetic2): Remove. (real_value_negate, real_value_abs): New prototypes. (do_mpc_arg2, real_from_mpfr, mpfr_from_real): Move from here... * realmpfr.h (do_mpc_arg2, real_from_mpfr, mpfr_from_real): ...to here, new include file for interface between MPFR and REAL_VALUE_TYPE. * real.c: Include realmpfr.h. (real_arithmetic2): Remove legacy function. (real_value_negate): New. (real_value_abs): New. (mfpr_from_real, real_from_mpfr): Move from here... * realmpfr.c (mpfr_from_real, real_from_mpfr): ...to here, new file. * builtins.c: Include realmpfr.h. * fold-const.c: Include realmpfr.h. (fold_comparison): Use real_value_negate instead of REAL_VALUE_NEGATE. (fold_negate_const): Likewise. (fold_abs_const): Use real_value_abs instead of REAL_VALUE_ABS. * toplev.c: Include realmpfr.h. * simplify-rtx.c (simplify_const_unary_operation): Use real_value_abs and real_value_negate. * fixed-value.c (check_real_for_fixed_mode): Likewise. * config/arm/arm.c (neg_const_double_rtx_ok_for_fpa): Likewise. (vfp3_const_double_index): Likewise. (arm_print_operand): Likewise. * Makefile.in: Update dependencies. fortran/ChangeLog: * trans-const.c: Include realmpfr.h. * Make-lang.in: Update dependencies.
