[LLVMdev] Nested Loop Unrolling
Hi, In LLVM (using the opt tool), is it possible to force a nested loop be unrolled entirely? Something like a pass option? I have a nested loop with depth of 4, and all trip counts are known at compile time, but so far I've only been able to do this by 4 invocations of the -loop-simplify, -loop-rotate, -loop-unroll passes. Thanks, Ali
