quadmath-rounding-mode.h: New.
2012-11-23 Tobias Burnus <burnus@net-b.de>
Joseph Myers <joseph@codesourcery.com>
* quadmath-rounding-mode.h: New.
* printf/fpioconst.c: Update from GLIBC. Fix strtod rounding.
* printf/fpioconst.h: Ditto.
* printf/printf_fp.c (__quadmath_printf_fp): Update from GLIBC.
Make printf respect the rounding mode for decimal output.
* printf/printf_fphex.c (__quadmath_printf_fphex): Update from
GLIBC. Make printf respect the rounding mode for hex output.
* strtod/strtod_l.c: Update from GLIBC. Make strtod respect the
rounding mode. Fix strtod handling of underflow.
