* real.c (real_maxval): New function to return the largest finite
value representable in a given mode (i.e. FLT_MAX and DBL_MAX).
* real.h (real_maxval): Prototype here.
* fold-const.c (fold_inf_compare): Transform comparisons against
+-Infinity into comparisons against DBL_MAX (or equivalent).
* gcc.c-torture/execute/ieee/inf-2.c: New test case.
