> Thanks for all your reply. I have one simple question to ask. I am new to llvm. I know that the loop to be optimized has to be enclosed between #pragma scop and #pragma endoscop.

#pragma scop/endscop are used by polyhedral source-to-source
optimizers such as ppcg[1] and OpenScop[2]. LLVM's polyhedral
optimizer Polly does not use them.

Polly has several report options available, such as
`-Rpass-analysis=polly-scops`, `-mllvm -polly-report`, `-mllvm
-polly-show`.
