TI->SF and TI->DF conversions in libgcc2.c:
FSTYPE
FUNC (DWtype u)
{
...
}
have no rounding mode support. We should replace __floattisf, __floattidf,
__floatuntisf and __floatuntidf in libgcc2.c with these from soft-fp.
PR libgcc/88931
* config/i386/64/t-softfp-compat (libgcc2-ti-functions): New.
(LIB2FUNCS_EXCLUDE): Likewise.
(libgcc2-ti-softp): Likewise.
(LIB2ADD): Likewise.
