Hi, all I wrote a pass that will instrument some instructions in the given program. However, the pass failed to pass "TODO_verify_stmts". The error message said "incorrect sharing of tree nodes". What's the meaning of this error message? If I just ignore "TODO_verify_stmts", it seems the instrumented program can still run. Can anybody give me some idea about the error? Thanks Haifeng --------------------------------------------------------------- The particular failed test program is like the following: Original gimple code: D.2582 = l->next Instrumented code +D.2585 = l->next +D.2586 = (int) D.2585 D.2582 = l->next +_my_call(D.2586) The error message is: error: incorrect sharing of tree nodes D.2582 = lD.2580->nextD.2569 lD.2580->nextD.2569
