[PATCH v5 5/7] math: Remove the SVID error handling from sinhf

[Wilco Dijkstra]

Hi Adhemerval,

           if (ux << 8)
             return x + x;                            /* nan */
           return copysignf (INFINITY, x); /* +-inf */

??? That's just return x;

         }
-      float r = math_narrow_eval (sgn * 0x1.fffffep127f);
-      return r;
+      return __math_oflowf (x < 0);

OK with that change.
