Hello folks,
<div><br></div><div>I wrote a transforming looppass for my project, opt --help can see it. I want clang to use my pass too, so that I don't have to compile to IR, opt, and then llc to binary manually. Now I am trying to add my pass to O2 by mimicking LICM pass. </div>
<div><br></div><div>I add a line "MPM.add(createMyPass());" in PassManagerBuilder::populateModulePassManager, and got assertion fail "void llvm::PMTopLevelManager::schedulePass(llvm::Pass*): Assertion `PI && "Expected required passes to be initialized"' failed." I can't figure out how to solve this? thanks for any inputs.</div>
