I'm trying to conver the conditions in IfStmt, so I need to recognize all possible cases. Obviously I may have to deal with GtExpr, GeExpr, LeExp, LtExpr, EqExpr and NeExpr. I wonder, however if I should consider CmpExpr, CmpgExpr and CmplExpr, too. Frankly, I don't even know why they exist in Soot.

What expression do they represent?

Regrads,
Jooyong
