[Bug target/11877] gcc should use xor trick with -Os



------- Additional Comments From kazu at cs dot umass dot edu  2004-03-25 19:16 -------
Even if you split the long move in ix86_expand_move,
the constant 0 is propagated into the two moves.
I guess the right way may be uncse sometime after register allocation.
