Hi Hal, James told me that in PassManagerBuilder.cpp, BarrierNoopPass is already used for this kind of purpose(though there's also a fixme saying it's hacking). I think it's a good idea to use this pass here. Thanks, Kevin 2015-03-11 17:05 GMT+08:00 Hal Finkel <hfinkel at anl.gov>: > ----- Original Message ----- > > From: "Kevin Qin...

Dear all, I wrote a machine function pass to run with llc. But I get this error while building: "/home/erdem/llvm/lib/CodeGen/CodeGen.cpp:80: error: undefined reference to 'llvm::initializeNoopInserterPass(llvm::PassRegistry&)'" NoopInserter is the name of my pass. I already added this line to InitializePasses.h: "void

Hi LLVM developers, I want to add LICM pass after loop unrolling pass in current optimization pipeline. Because both of them are loop passes, so if I registered them one by one, they will interleaved go through all loops in bottom up way within same loop pass manager. Loop unroling pass may create new inner loops from partial unrolling, and those newly created loops can be visited only if the
