...cribe should be possible. In your GCStrategy subclass constructor, make the following change: class MyGCStrategy : public GCStrategy { MyGCStrategy() { - InitRoots = true; + CustomRoots = true; } + + bool performCustomLowering(Function &F) { + // You can use LowerIntrinsics::InsertRootInitializers as a template. + } }; LowerIntrinsics::InsertRootInitializers is only 26 lines of code. You can find it here: http://llvm.org/viewvc/llvm-project/llvm/trunk/lib/CodeGen/GCStrategy.cpp?annotate=123170#l174 More invasively, you could consider adding a hook to GCStrategy which replaces the in...

Hello all, I set: InitRoots = true; in my gc plugin as i want the roots to be initialized to the "null" value. Is there a way to define which value should be the initial one? For example, i would like to initialize my roots to -5 (tagged, null value for the GC in my runtime system) instead of 0. Ofcourse, i could do it in the frontend (storing -5 to all GC roots), but i was wondering

Hi I'm getting an assert in LowerIntrinsics::InsertRootInitializers because I'm gcroot'ing an alloca to a non-pointer. I was hoping to modify InsertRootInitializers to memset the structure in the case that it's not a pointer, but I'm not sure how to. Can anyone suggest what should go at "todo; something here"? ... for (AllocaInst **I...
