Hi,
Maybe you can try the #pragmas. Check this: http://clang.llvm.org/docs/LanguageExtensions.html#loop-unrolling and this example: https://godbolt.org/z/rhdUDp
Best, Stefanos

Hi,
I'm interesting in find a pass for loop unrolling in LLVM compiler. I tried opt --loop-unroll --unroll-count=4, but it don't work well. What pass I can used and how? I would also like to know if there is any way to mark the loops that I want them to be unroll Thanks you.
