* soft-fp/op-common.h (FP_TRUNC): Replace raising of FP_EX_INEXACT cvs/fedora-glibc-20070504T0917
with setting the sticky bit. * math/test-misc.c (main): Add more truncation tests. * soft-fp/floatunsidf.c (__floatunsidf): Use DFtype instead of double in the function declaration. * soft-fp/floatundidf.c (__floatundidf): Use DFtype instead of double in the function declaration. * soft-fp/floatunsisf.c (__floatunsisf): Use SFtype instead of float in the function declaration. * soft-fp/floatunsisf.c (__floatunsisf): Use SFtype instead of float in the function declaration. * soft-fp/extended.h (FP_UNPACK_RAW_E): Do not increase X##_e for denormal operands. Do not generate FP_EX_DENORM exception. (FP_UNPACK_RAW_EP): Ditto. (FP_UNPACK_SEMIRAW_E): Use FP_UNPACK_RAW_E instead of undefined _FP_UNPACK_RAW_E.

(FP_PACK_SEMIRAW_EP): Use FP_PACK_RAW_EP instead of undefined _FP_PACK_RAW_EP. * op-2.h (_FP_FRAC_COPY_2_2): Define as alias to _FP_FRAC_COPY_2. * op-4.h (_FP_FRAC_COPY_2_2): Define as alias to _FP_FRAC_COPY_4. * soft-fp/op-common.h (FP_EXTEND): Do not abort when _FP_EXPBIAS_##dfs == _FP_EXPBIAS_##sfs. Handle denormals for this case. * soft-fp/op-common.h (FP_TRUNC): Ditto. * soft-fp/op-common.h (FP_TRUNC): Replace raising of FP_EX_INEXACT with setting the sticky bit. * math/test-misc.c (main): Add more truncation tests. 2007-04-14 Uros Bizjak <ubizjak@gmail.com> * soft-fp/floatunsidf.c (__floatunsidf): Use DFtype instead of double in the function declaration. * soft-fp/floatundidf.c (__floatundidf): Use DFtype instead of double in the function declaration. * soft-fp/floatunsisf.c (__floatunsisf): Use SFtype instead of float in the function declaration. * soft-fp/floatunsisf.c (__floatunsisf): Use SFtype instead of float in the function declaration. * soft-fp/extended.h (FP_UNPACK_RAW_E): Do not increase X##_e for denormal operands.
