Comparison operators test a relation on two operands and are considered
to represent a machine-dependent nonzero value described by, but not
necessarily equal to, @code{STORE_FLAG_VALUE} (@pxref{Misc})
if the relation holds, or zero if it does not. The mode of the
comparison operation is independent of the mode of the data being
compared. If the comparison operation is being tested (e.g., the first
operand of an @code{if_then_else}), the mode must be @code{VOIDmode}.
If the comparison operation is producing data to be stored in some
variable, the mode must be in class @code{MODE_INT}. All comparison
operations producing data must use the same mode, which is
machine-specific.
if the relation holds, or zero if it does not, for comparison operators
whose results have a `MODE_INT' mode, and
@code{FLOAT_STORE_FLAG_VALUE} (@pxref{Misc}) if the relation holds, or
zero if it does not, for comparison operators that return floating-point
values. The mode of the comparison operation is independent of the mode

There are two ways that comparison operations may be used. The
