...o llvm.gcroot() intrinsics by temporarily storing the the root into an alloca and then reloading it as needed. (Actually you would probably want something richer than the current llvm.gcroot that allows an explicit begin and end so that information about liveness can be preserved. How about llvm.gc.beginroot() intrinsic to indicate that a given alloca should be considered a root starting at that point in the CFG, and llvm.gc.endroot() to indicate that the specified root no longer needs to be considered a root. This is much better than the current method of assigning NULL to a root, as it accommodates n...

I think I'm one of the few people actually using LLVM's support for garbage collection, and so far I've found it very difficult to generate code that uses llvm.gcroot() correctly. In the current scheme, it is the frontend's responsibility to insure that any intermediate SSA values containing references to garbage collectible objects are copied to stack variables so that the GC
