2021-08-23stdlib: conditionalize locale usageCorinna Vinschen1-3/+9
_strtod_l as well as the gethex function both fetch the decimal point from the current LC_NUMERIC locale info. This pulls in _C_numeric_locale unconditionally even on targets not supporting locales at all. Another problem is that strtod.c and gdtoa-gethex.c are ELIX 1, while locale information in general isn't. This leads to potential build breakage on bare metal targets. Fix this by setting the decimal point to "." on all targets not defining __HAVE_LOCALE_INFO__. While at it, const'ify the entire local decimal point info in the affected functions.

2020-01-09Prevent more NULL ptr accesses due to Balloc out of memoryJeff Johnston1-2/+2
- fix gdtoa-gethex.c, ldtoa.c, and strtodg.c to use eBalloc
2018-09-06stdlib: Use __get_numeric_locale instead of __localeconv_l for decimal_pointKeith Packard1-2/+2
The string/float conversion functions need to get the locale decimal point. Instead of calling __localeconv_l (which copies locale data into lconv form from __get_numeric_locale), use __get_numeric_locale directly. Signed-off-by: Keith Packard <keithp@keithp.com>
2018-08-16Remove unused NaN's integer representation definitionsMasamichi Hosoda1-1/+0
By previous commit, strto{d|ld} ("nan") does not use the definition of NaN. There is no other function that uses the definitions. This commit remove the definitions.
