Probably because it was optimized.  If you want a better answer, you 
have to give us more info about what happened, such as a C testcase, and 
RTL dumps.  But it is probably better if you look at this yourself. 
Generate debugging dumps, -da -fdump-tree-all, and then start looking. 
Presumably an XOR was generated at first, and then got optimized to an 
scond at some point.
