real.h (struct real_format): New member has_sign_dependent_rounding.

	* real.h (struct real_format): New member has_sign_dependent_rounding.
	* real.c (ieee_single_format, mips_single_format, motorola_single_format,
	spu_single_format, ieee_double_format, mips_double_format,
	motorola_double_format, ieee_extended_motorola_format,
	ieee_extended_intel_96_format, ieee_extended_intel_128_format,

	mips_extended_format, ieee_quad_format, mips_quad_format,
	vax_f_format, vax_d_format, vax_g_format): Initialize it.
	* config/pdp11/pdp11.c (pdp11_f_format, pdp11_d_format): Likewise.

	* defaults.h (MODE_HAS_NANS, MODE_HAS_INFINITIES,
	MODE_HAS_SIGNED_ZEROS, MODE_HAS_SIGN_DEPENDENT_ROUNDING): Remove.
	* config/spu/spu.h (MODE_HAS_NANS, MODE_HAS_INFINITIES,
	MODE_HAS_SIGN_DEPENDENT_ROUNDING): Remove.
	(ROUND_TOWARDS_ZERO): Likewise.

	* real.h (REAL_MODE_FORMAT): Protect MODE against macro expansion.
	(FLOAT_MODE_FORMAT): New macro.
	(REAL_MODE_FORMAT_COMPOSITE_P): Remove, replace by ...
	(MODE_COMPOSITE_P): ... this new macro.
	(MODE_HAS_NANS, MODE_HAS_INFINITIES, MODE_HAS_SIGNED_ZEROS,

	* machmode.h (GET_MODE_INNER): Cast result to enum machine_mode.

	* flags.h: Include "real.h".

	* fold-const.c (const_binop): Use MODE_COMPOSITE_P instead of
	REAL_MODE_FORMAT_COMPOSITE_P.
	* simplify-rtx.c (simplify_const_binary_operation): Likewise.

	* doc/tm.texi (Storage Layout): Remove documentation of
	MODE_HAS_NANS, MODE_HAS_INFINITIES, MODE_HAS_SIGNED_ZEROS,
	MODE_HAS_SIGN_DEPENDENT_ROUNDING.  Update documentation of
	ROUND_TOWARDS_ZERO and LARGEST_EXPONENT_IS_NORMAL to clarify
	they only apply to libgcc2.a.
