Re: GIMPLE and intent of variables

During determining the intent of variable I run into problems with PHI nodes. The problematical GIMPLE code looks: # BLOCK 196 # PRED: 194 (false) (...) ndycD.8665_1099 = 1; # BLOCK 197 # PRED: 196 (true) 207 (false) # ndycD.8665_4 = PHI (...) # BLOC

Re: GIMPLE and intent of variables

Thank you for all the answers. Now I have another problem. When I reach a function call during statement iteration, I want to go to this function's code. if (is_gimple_call(stmt)) { tree fndecl = gimple_call_fndecl(stmt); // This returns function_decl ;-)
