This version, again relative to a tree with my strtod integer overflow patch <http://sourceware.org/ml/libc-alpha/2012-08/msg00202.html> (pending review) applied, includes the generators and input file in the source tree, with comments on the generated tables pointing to the generators, but is otherwise unchanged. 2012-08-15 Joseph Myers <joseph@codesourcery.com> [BZ #3479] * stdlib/strtod_l.c (NDIG): Remove. (HEXNDIG): Likewise. (MPNSIZE): Increase to represent 10^n where 2^-n is 1/4 ulp of the smallest representable value. (____STRTOF_INTERNAL): Use all fractional decimal digits that may lie within an exact representation of 1/2 ulp of the result. * stdlib/fpioconst.c (__tens): Include 10^2^9 and 10^2^10 unconditionally. (TENS_P9_IDX): Define unconditionally. (TENS_P9_SIZE): Likewise. (TENS_P10_IDX): Likewise. (TENS_P10_SIZE): Likewise. [BITS_PER_MP_LIMB == 32]: Change condition for larger powers of 10 to !defined __NO_LONG_DOUBLE_MATH && __LDBL_MAX_EXP__ > 1024. [!__NO_LONG_DOUBLE_MATH && __LDBL_MAX_EXP__ > 1024] (__tens): Add entries for 10^2^13 and 10^2^14. [!__NO_LONG_DOUBLE_MATH && __LDBL_MAX_EXP__ > 1024] (TENS_P13_IDX): Define. (TENS_P13_SIZE): Likewise. (TENS_P14_IDX): Likewise. (TENS_P14_SIZE): Likewise. (_fpioconst_pow10): Change array size to FPIOCONST_POW10_ARRAY_SIZE. Make entries for 10^2^9 and 10^2^10 unconditional. (_fpioconst_pow10) [!__NO_LONG_DOUBLE_MATH && __LDBL_MAX_EXP__ > 1024]: Add entries for 10^2^13 and 10^2^14. [LAST_POW10 > _LAST_POW10]: Remove #error. * stdlib/fpioconst.h (FPIOCONST_POW10_ARRAY_SIZE): Define. (_fpioconst_pow10): Change array size to FPIOCONST_POW10_ARRAY_SIZE. * stdlib/gen-fpioconst.c: New file. * stdlib/gen-tst-strtod-round.c: Likewise. * stdlib/tst-strtod-round-data: Likewise. * stdlib/tst-strtod-round.c: Likewise. * stdlib/Makefile (tests): Add tst-strtod-round.
