* Add tst-wcstod-roundPaul E. Murphy2016-08-191-199/+7
| | | | | | This extends tst-strtod-round with a few trivial changes to also test the wide character variants of strto* using similar macros to other shared tests.
* Refactor tst-strtod-round.c for type-generic-nessPaul E. Murphy2016-05-251-158/+146
| | | | | Reduce much of the redundancy in this file, and attempt to coral the type specific stuff to ease adding an new type.
* Refactor tst-strtod-round.cPaul E. Murphy2016-05-241-12336/+2
| | | | | | | | | | This file is partially generated. To make updates a little simpler, I have moved the generated code into a partially contained header to simplify regeneration. gen-tst-strtod-round.c now takes two, mandatory arguments. These arguments specify the input test data and the output destination, respectively.

* Fix strtof decimal rounding close to half least subnormal (bug 18247).Joseph Myers2015-04-101-0/+4638
| | | | | | | | | | | | | | | | | | | | | Bug 18247 is an off-by-one error in strtof's determination of a decimal exponent such that any value with that decimal exponent is at most half the least subnormal and so the appropriate underflowing value for the rounding mode can be determined with no multiple-precision computations. (Whether the value is in fact safe despite the off-by-one depends on the floating-point format in question. It's wrong for float and for m68k ldbl-96 but not for other supported formats.) This patch corrects the computation of the exponent in question to be safe in general, adding a comment explaining the new computation. Tested for x86_64. [BZ #18247] * stdlib/strtod_l.c (____STRTOF_INTERNAL): Decrease minimum decimal exponent by 1. * stdlib/tst-strtod-round-data: Add more tests. * stdlib/tst-strtod-round.c (tests): Regenerated.

* Fix some warnings in the absence of FP round/exception supportChris Metcalf2014-12-301-1/+1
| | | | | | | Due to tile missing a bunch of FP exception and rounding support, the tests generate warnings. These changes fix the warnings by just not compiling some unused functions, and adding some attribute ((unused)) tags.
* stdlib/tst-strtod-round.c: Fix build on ARMWill Newton2014-09-301-0/+3
| | | | | | | | | | | | | | | | | Building this test on ARM fails because the prototypes for the long double variants of the math functions are unavailable. Add an additional include guard to math.h that enables long double math function declarations if _LIBC_TEST is defined and define _LIBC_TEST in stdlib/tst-strtod-round.c. ChangeLog: 2014-09-30 Will Newton <will.newton@linaro.org> * math/math.h: Define long double math functions if _LIBC_TEST is defined. * stdlib/tst-strtod-round.c: Define _LIBC_TEST.
