History
Joseph Myers a04bb3306a Fix ldbl-128 expm1l (-min_subnorm) result sign (bug 18619). 
In the ldbl-128 implementation of expm1l, when expm1l's result should
underflow to 0 (argument minus the least subnormal, in some rounding
modes), it can be a zero of the wrong sign.  This patch fixes this in
the same way previously used for the x86 / x86_64 versions.

Tested for mips64.

	[BZ #18619]
	* sysdeps/ieee754/ldbl-128/s_expm1l.c (__expm1l): Force underflow
	and return argument in case of subnormal argument.
