Update.
2002-07-03 Jakub Jelinek <jakub@redhat.com> * stdio-common/printf_fp.c (__printf_fp.c): If _FPIO_CONST_SHIFT is non-zero, adjust exponent. * sysdeps/ieee754/ldbl-128/s_erfl.c (__erfl, erfl, __erfcl, erfcl): Remove NO_LONG_DOUBLE aliases. * sysdeps/ieee754/ldbl-128/s_expm1l.c (__expm1l, expm1l): Likewise. * sysdeps/ieee754/ldbl-128/s_log1pl.c (__log1pl, log1pl): Likewise. (__log1pl): Raise divide by zero and invalid exceptions when needed. * sysdeps/ieee754/ldbl-128/e_powl.c (__ieee754_powl): Special case 1**y and -1**+-Inf. * sysdeps/ieee754/ldbl-128/ldbl2mpn.c (__mpn_extract_long_double): Fix BITS_PER_MP_LIMB 32 extraction. * sysdeps/ieee754/ldbl-128/e_log2l.c (__ieee754_log2l): Don't raise exceptions for qNaNs. * sysdeps/ieee754/ldbl-128/e_log10l.c (__ieee754_log10l): Likewise. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgamma_r): Raise exceptions when needed. Don't recurse unnecessarily. Special case 1.0L and 2.0L arguments to avoid -0.0L as result. * sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_y0l): Don't raise exceptions for qNaNs. * sysdeps/ieee754/ldbl-128/s_remquol.c (__remquol): Make qs 64-bit to fix *quo return value sign. * sysdeps/ieee754/ldbl-128/e_gammal_r.c (__ieee754_gamma_r): Special case -Inf argument. * soft-fp/op-4.h (_FP_FRAC_CLZ_4): Fix a pasto. 2002-07-01 Jakub Jelinek <jakub@redhat.com> * libio/tst-eof.c (do_test): Remove unused ch and tm variables. * iconvdata/iso-2022-jp-3.c (EMIT_SHIFT_TO_INIT): Kill warnings if -DNDEBUG.
