ChangeLog:gcc-4_3_2-rc1
* 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.
* config/spu/float_disf.c: New file.
* config/spu/float_unsdisf.c: New file.
* config/spu/t-elf (LIB2FUNCS_STATIC_EXTRA): Add them.
(LIB2FUNCS_EXCLUDE): Define.
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.
* gcc.dg/torture/fp-int-convert-float.c: Reenable test on SPU.
* gcc.dg/torture/fp-int-convert-timode.c: Reenable "float" test on SPU.
