The documentation in rtl.texi for the HIGH and LO_SUM operators incorrectly say
that they should use Pmode. There is no such restriction. They can be used
with any mode. Pmode is only necessary if the operand is an address, such as a
SYMBOL_REF or a LABEL_REF. The text will need some rewording to make this clear.

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-02-04 00:52:00 UTC ---
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
bits set by @code{high}.
@var{m} should be @code{Pmode}.
The last part is what is incorrect.
