  "message": "Add contains_zero_p to the vrange hierarchy.\n\nIntroduce a contains_zero_p() predicate on vrange and company,\nreturning whether the range contains zero.  It is a clearer\nreplacement for nonzero_p(), which only holds for the exact ~[0,0]\nrange.\n\nTested on ppc64le Linux.\n\ngcc/ChangeLog:\n\n\t* value-range.h (vrange::contains_zero_p): New pure virtual.\n\t(unsupported_range::contains_zero_p): Declare.\n\t(irange::contains_zero_p): Declare and define.\n\t(prange::contains_zero_p): Declare and define.\n\t(frange::contains_zero_p): Declare.\n\t(Value_Range::contains_zero_p): New.\n\t* value-range.cc (unsupported_range::contains_zero_p): Define.\n\t(frange::contains_zero_p): Define.\n",
