[LLVMdev] inserting a fucntion call at the end of basic bloc
hi all, i would like insert a fucntion call at the end of each basic bloc the fucntion i have defined and declared at the begining of the module ie i have written a pass derived from a module pass virtual bool runOnModule(Module & M){ // i declared the fucntion and defined it for (Module::iterator a = M.begin(), b = M.end(); a != b; for (Function::iterator i = a->begin(), e = a->end(); i != e; ++i) { //call the function } } } i tried to see an example with the demo, i saw that it instead of calling the function, it repeats all the instruction that are existing in the function Any help? -------------- next part -------------- An HTML attachment was scrubbed...

[LLVMdev] inserting a fucntion call at the end of basic bloc
Hi Nabila,> i would like insert a fucntion call at the end of each basic blocyou can't, because only terminators are allowed at the end of a basic block. However you can try to insert the call before the terminator. ...> i tried to see an example with the demo, i saw that it instead of calling the > function, it repeats all the instruction that are existing in the function > Any help?Turn off optimization in the demo (optimization level "None"). Ciao, Duncan.
