PR bootstrap/13848
* cse.c (cse_cc_succs): Change the mode of the source expression
as soon as decide we need a new mode. Don't permit changing modes
if we found a match in a successor block.
(cse_condition_code_reg): Save original mode of source expression
so that we know whether we have to change the mode in other
insns.
* gcc.dg/20040124-1.c: New test.
