libgcc2.c: Correct DI/TI -> SF/DF conversions
FSTYPE FUNC (DWtype u) in libgcc2.c, which converts DI/TI to SF/DF, has
/* No leading bits means u == minimum. */
if (count == 0)
return -(Wtype_MAXp1_F * (Wtype_MAXp1_F / 2));
in the third case (where actually count == 0 only means the high part is
minimum). It should be:
/* No leading bits means u == minimum. */
if (count == 0)
return Wtype_MAXp1_F * (FSTYPE) (hi | ((UWtype) u != 0));
instead.
