[LLVMdev] Initializing GC roots
...ng the GC > plugin and implementing custom lowering for the gcroot intrinsic. Hello Yiannis, Yes, what you describe 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.

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
