optabs.c (prepare_float_lib_cmp): Use libgcc_cmp_return_mode instead of word_mode.
2007-08-31 Andrew Pinski <andrew_pinski@playstation.sony.com>
* optabs.c (prepare_float_lib_cmp): Use
libgcc_cmp_return_mode instead of word_mode.
* config/dfp-bit.h: Likewise.
* config/fp-bit.h: Likewise.
* config/spu/spu.c (spu_libgcc_cmp_return_mode):
New function.
(spu_libgcc_shift_count_mode): New function.
(TARGET_LIBGCC_CMP_RETURN_MODE): Define.
(TARGET_LIBGCC_SHIFT_COUNT_MODE): Define.
