 Then the integers are replaced by sub-initializers, braced groupings containing
 several integers.  Each sub-initializer must be suitable as an initializer
 for the type @code{HARD_REG_SET} which is defined in @file{hard-reg-set.h}.
+In this situation, the first integer in each sub-initializer corresponds to
+registers 0 through 31, the second integer to registers 32 through 63, and
+so on.
