Unable to access rhs[1] of gcc.GimpleAssign statement
by LUCKY AGARWAL 18 Apr '14

18 Apr '14

Hi I am trying to build a custom pass but i am facing a discrepancy in the GimplePass and IpaPass, My code in both cases is: if isinstance(stmt, gcc.GimpleAssign): if isinstance(stmt.lhs,gcc.VarDecl): kill1.update([str(stmt.lhs)]) if isinstance(stmt.rhs[0],gcc.VarDecl): gen1.update([str(stmt.rhs[0])]) if len(stmt.rhs) != 1 : if isinstance(stmt.rhs[1],gcc.VarDecl): gen1.update([str(stmt.rhs[1])]) This works fine in case of intraprocedural pass, but in case of interprocedural pass the len(stmt.rhs) throws errors like, if len(stmt.rhs) != 1 : AttributeError: 'gcc.GimpleReturn' object has no attribute 'rhs' or if len(stmt.rhs) != 1 : TypeError: object of type 'gcc.SsaName' has no len() Please help me out. I can share the full code too if required. Thanks
