Remove unnecessary test for denormal exponent. + * sysdeps/ieee754/ldbl-128ibm/ldbl2mpn.c (__mpn_extract_long_double): + Correct handling of denormals. Avoid undefined shift behaviour. + Correct normalisation of low mantissa when low double is denormal. + * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h + (ldbl_extract_mantissa): Likewise. Comment. Use uint64_t* for hi64. + (ldbl_insert_mantissa): Make both hi64 and lo64 parms uint64_t. + Correct normalisation of low mantissa. Test for overflow of high + mantissa and normalise. + (ldbl_nearbyint): Use more readable constant for two52. + * sysdeps/ieee754/ldbl-128ibm/mpn2ldbl.c + (__mpn_construct_long_double): Fix test for overflow of high + mantissa and correct normalisation.
