@item @samp{add@var{mode}cc}
Similar to @samp{mov@var{mode}cc} but for conditional addition. Conditionally
move operand 2 or (operands 2 + operand 3) into operand 0 according to the
-comparison in operand 1. If the comparison is true, operand 2 is moved into
+comparison in operand 1. If the comparison is false, operand 2 is moved into
operand 0, otherwise (operand 2 + operand 3) is moved.
@cindex @code{cstore@var{mode}4} instruction pattern
the mode to use should they be constants. If it is VOIDmode, they cannot
both be constants.
- OP2 should be stored in TARGET if the comparison is true, otherwise OP2+OP3
+ OP2 should be stored in TARGET if the comparison is false, otherwise OP2+OP3
should be stored there. MODE is the mode to use should they be constants.
If it is VOIDmode, they cannot both be constants.
