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

ChangeLog:

	* real.h (struct real_format): New member round_towards_zero.
	* real.c (round_for_format): Respect fmt->round_towards_zero.
	(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,
	ieee_extended_intel_96_round_53_format, ibm_extended_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.

	* builtins.s (do_mpfr_arg1): Consider round_towards_zero member of
	real_format to choose rounding mode when calling MPFR functions.
	(do_mpfr_arg2, do_mpfr_arg3, do_mpfr_sincos): Likewise.
	(do_mpfr_bessel_n, do_mpfr_remquo, do_mpfr_lgamma_r): Likewise.

	* real.h (real_to_decimal_for_mode): Add prototype.
	* real.c (real_to_decimal_for_mode): Renames old real_to_decimal.
	Respect target rounding mode when generating decimal representation.
	(real_to_decimal): New stub for backwards compatibility.
	* c-cppbuiltin.c (builtin_define_with_hex_fp_value): Use
	real_to_decimal_for_mode instead of real_to_decimal.

	* config/spu/spu.md ("floatdisf2", "floatunsdisf2"): New.


testsuite/ChangeLog:

	* gcc.c-torture/execute/20031003-1.c (main): Update test to
	accommodate SPU single-precision rounding mode.
	* gcc.c-torture/execute/conversion.c (test_float_to_integer,
	test_float_to_longlong_integer): Likewise.
	* gcc.c-torture/execute/ieee/rbug.c (main): Likewise.
	* gcc.dg/hex-round-1.c: Skip test on SPU.
	* gcc.dg/hex-round-2.c: Likewise.
