--- Comment #4 from Richard Earnshaw <rearnsha at gcc dot gnu.org> 2012-03-01 16:08:35 UTC --- The real question is why is a cstore operation being called with constants for the two operands in the comparison. If it knows the constants, then it knows the result of the comparison and can collapse the entire result.
