 The @code{__builtin_cmpb} function
 performs a byte-wise compare on the contents of its two arguments,
 returning the result of the byte-wise comparison as the returned
 value.  For each byte comparison, the corresponding byte of the return
-value holds 0xff if the input bytes are equal, and 0 if the input bytes
+value holds 0xff if the input bytes are equal and 0 if the input bytes
 are not equal.  If either of the arguments to this built-in function
 is wider than 32 bits, the function call expands into the form that
 expects @code{unsigned long long int} arguments
