The tst-strtod-round-skeleton.c conditionals relating to handling of
_Float64x require associated <float.h> macros, which requires
__STDC_WANT_IEC_60559_TYPES_EXT__ to be defined before <float.h> is
included if _Float64x is supported. This patch adds the necessary
definition.
Tested for x86_64, including in conjunction with _Float64x support
patches.
* stdlib/tst-strtod-round-skeleton.c
(__STDC_WANT_IEC_60559_TYPES_EXT__): Define before including
headers.

Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch adds support to type-generic strtod tests.
GEN_STRTOD_TEST_FOREACH and STRTOD_TEST_FOREACH are made to handle the
full set of such types. tst-strtod-round-skeleton.c is updated for
those types it can handle without needing changes to the generator
(i.e. those types that have already-handled formats).
Tested for x86_64.

The strtod function should raise the "inexact" exception when its
result is inexact, but fails to do so except in the case of underflow
or overflow. This patch fixes it to do so for all inexact results.
tst-strtod-round is extended to test for this exception; the generator
is fixed to properly mark inexact results as such in the case where
the inexactness is from the mpfr_subnormalize step.
Tested for x86_64, x86 and powerpc.
[BZ #19380]
* stdlib/strtod_l.c (round_and_return): Force "inexact" exception
for inexact results.
* stdlib/gen-tst-strtod-round.c (string_to_fp): Return indication
of inexact result where mpfr_subnormalize is the only inexact
step.
* stdlib/tst-strtod-round-data.h: Regenerated.
* stdlib/tst-strtod-round-skeleton.c [!FE_INEXACT] (FE_INEXACT):
Define to 0.
(GEN_ONE_TEST): Test inexact exceptions raised are as expected.

This patch changes strtod* tests to use strfrom* functions.
|
|
|
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.
