--- Comment #3 from Roger Sayle <roger at nextmovesoftware dot com> ---
One solution might be to introduce a BIT_AOP_EXPR which behaves like
BIT_IOR_EXPR and BIT_XOR_EXPR and PLUS_EXPR, relying on the semantics that the
bits in its two operands are disjoint (i.e. (op0 & op1) == 0). The backend can
then decide which operation to actually use during RTL expansion.
[But I also agree with Uros; on x86 the PLUS is more useful than the IOR.]
