Chris Lattner fe8af82cd4 Teach codegen to handle: ... (X != null) | (Y != null) --> (X|Y) != 0 (X == null) & (Y == null) --> (X|Y) == 0 so that instcombine can stop doing this for pointers. This is part of PR3351, which is a case where instcombine doing this for pointers (inserting ptrtoint) is pessimizing code. llvm-svn: 92406		2010-01-02 00:00:03 +00:00
