You can't do that; switch cases are required to be constant integers, and a blockaddress are not constant integers (at least not at compile-time). You can use an explicit comp...

Hi All, Value* V; Value* V2; BasicBlock * BB; unsigned j; ///number of cases .... //insert V , V2, j and BB SwitchInst* sw= builder.CreateSwitch(V, BB, j); ConstantInt * CI= dyn_cast<ConstantInt>(V2); sw-> addCase( CI , BB); At last step there is Program received signal SIGSEGV, Segmentation fault. What is wrong in the code? Thanks in advance -- * Rasha Salah Omar Msc Student at E-JUST Demonestrator at Faculty of Computers and Informatics Benha University* * e-mail: rasha.omar at...
