This expression represents the sum of @var{x} and the low-order bits
of @var{y}. It is used with @code{high} (@pxref{Constants}) to
represent the typical two-instruction sequence used in RISC machines
-to reference a global memory location.
+to reference a global memory location.
The number of low order bits is machine-dependent but is
normally the number of bits in a @code{Pmode} item minus the number of
