llvm.set.loop.iterations
After playing a bit with the newly introduced hardware loop framework I realize that the llvm.set.loop.iterations intrinsic takes as argument the number of iterations the loop will execute. In fact it goes all the way to, on IR, insert an addition of constant 1 to the number of taken backedges returned by SCEV.
If the machine instruction realizing the loop is interested in the number of
