[PATCH] D28031: Allow target to specify early module passes

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

What I can also do is to stop using extensions at all. I.e. write this into opt.cpp and BackendUtil.cpp:

     if (OptLevelO3)
       AddOptimizationPasses(Passes, *FPasses, TM.get(), 3, 0);
  
  +  // Add target-specific passes that need to run as early as possible.
  +  if (TM) {
  +    legacy::PassManager EarlyPasses;
  +    TM->addEarlyAsPossiblePasses(EarlyPasses);
  +    EarlyPasses.run(*M);
  +  }
  +
     if (FPasses) {
       FPasses->doInitialization();
