with unknown trip counts. This is left off by default, and a command-line option enables it. It also begins to separate loop unrolling into a utility routine; eventually it might be made usable from other passes. It currently works by inserting conditional branches between each unrolled iteration, unless it proves that the trip count is a multiple of a constant integer > 1, which it currently only does in the rare case that the trip count expression is a Mul operator with a ConstantInt operand. Eventually this information might be provided by other sources, for example by a pass that peels/splits the loop for this purpose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36990 91177308-0d34-0410-b5e6-96231b3b80d8 |
