OK for trunk?
Thanks.

Update soft-fp from glibc with:
commit 69da3c9e87e0a692e79db0615a53782e4198dbf0
Author: H.J. Lu <hjl.to...@gmail.com>
Date: Mon Jan 7 09:04:29 2019 -0800
quad.h have
#if _FP_W_TYPE_SIZE < 64
union _FP_UNION_Q
{
Use 4 _FP_W_TYPEs
}
#else
union _FP_UNION_Q
{
Use 2 _FP_W_TYPEs
}
#endif
Replace
#if (2 * _FP_W_TYPE_SIZE) < _FP_FRACBITS_Q
with
#if _FP_W_TYPE_SIZE < 64
to check whether 4 or 2 _FP_W_TYPEs are used for IEEE quad precision.
Tested with build-many-glibcs.py.
* soft-fp/extenddftf2.c: Use "_FP_W_TYPE_SIZE < 64" to check if
4_FP_W_TYPEs are used for IEEE quad precision.
* soft-fp/extendhftf2.c: Likewise.
* soft-fp/extendsftf2.c: Likewise.
* soft-fp/extendxftf2.c: Likewise.
* soft-fp/trunctfdf2.c: Likewise.
* soft-fp/trunctfhf2.c: Likewise.
* soft-fp/trunctfsf2.c: Likewise.
* soft-fp/trunctfxf2.c: Likewise.
* config/rs6000/ibm-ldouble.c: Likewise.
