2016-02-17 Thread Cristina Georgiana Opriceana
Hello, I inserted a new local var decl in gimple, a pointer which is malloc'ed and now I am trying to read/write in that memory. int *mumu; mumu = malloc ( 40 * sizeof (int)); mumu[1] = 10; The following statement: mumu[1] = 10; which should look like this MEM[(int *)mumu_10 + 4B] = 10; for me,
