Hi, all I found in some cases the int variable get promoted to i64, although I think it should i32. I use the online demo (http://llvm.org/demo). And below is the test case. ------------- test case ------------- int test(int x[], int y[], int n) { int i = 0; int sum = 0; for ( ; i < n; i++) { sum += x[i] * y[i]; } return sum; } ------------------------------------- No
