Macro Definition Documentation

#define ALL_ONES   (~((unsigned HOST_WIDE_INT) 0))

Referenced by double_int::from_buffer(), and double_int::operator^().

#define double_int_minus_one   (double_int::from_shwi (-1))

Some useful constants. FIXME(crowl): Maybe remove after converting callers? The problem is that a named constant would not be as optimizable, while the functional syntax is more verbose.
