title: Reducing the execution time of the code using CLANG/LLVM compiler
body: <p>Well... When i was searching for a good compiler I came across clang/LLVM. This compiler gives me same result as other compilers like icc, pgi. But the problem is there are very few tutorials on this compiler... Kindly let me know where can I find the tutorials on the clang compiler.</p>
  
  <p>Note by:
  I have compiled my c code using the following flags  <code>clang -O3 -mfpmath=sse file.c</code></p>
