Simplify test + for 0.0L. Correct |x|<|y| and |x|=|y| test. Use + ldbl_extract_mantissa value for ix,iy exponents. Properly + normalize after ldbl_extract_mantissa, and don't add hidden bit + already handled. Don't treat low word of ieee854 mantissa like + low word of IBM long double and mask off bit when testing for + zero. + * sysdeps/ieee754/ldbl-128ibm/e_hypotl.c (__ieee754_hypotl): Rewrite + all uses of ieee875 long double macros and unions. Simplify tests + for 0.0L and inf. Correct double adjustment of k. Delete dead code + adjusting ha,hb. Simplify code setting kld. Delete two600 and + two1022, instead use their values. Recognise that tests for large + "a" and small "b" are mutually exclusive. Rename vars. Comment. + * sysdeps/ieee754/ldbl-128ibm/e_remainderl.c (__ieee754_remainderl): + Rewrite all uses of ieee875 long double macros and unions. Simplify + test for 0.0L and nan. Correct negation. + * sysdeps/ieee754/ldbl-128ibm/s_erfl.c (__erfl): Rewrite all uses of + ieee875 long double macros and unions. Correct output for large + magnitude x. Correct absolute value calculation. + (__erfcl): Likewise. + * math/libm-test.inc: Add tests for errors discovered in IBM long + double versions of fmodl, remainderl, erfl and erfcl. + +2013-10-04 Alan Modra <amodra@gmail.com> + * sysdeps/ieee754/ldbl-128ibm/e_atan2l.c (__ieee754_atan2l): Rewrite all uses of ieee854 long double macros and unions. Simplify tests for long doubles that are fully specified by the high double. |
