...o study the impact of lli optimizations. here my IR is already optimized through opt. now i have to perform lli optimizations provided i am giving varying inputs at run time. so i suppose here my optimization level also depends on runtime input. like, i am using following command. time lli -O3 sum-vec03.ll 5 2 also after acquiring the execution time at different scenarios i plan to use some machine learning algorithm in order to predict the appropriate flag setting for given program and run time input. Please help. Does this look appropriate approach? is my methodology correct? Thank You -----...

Hello, I have written the following code. when i try to vectorize it through opt. i am not getting vectorized instructions. #include <stdio.h> #include<stdlib.h> int main(int argc, char** argv) { int sum=0; int a=atoi(argv[1]); int b=atoi(argv[2]); for (int i=0;i<1000;i++) { sum+=a+b; } printf("sum: %d\n", sum); return 0; } i use following commands: clang -S -emit-llvm
