[LLVMdev] Strange exception in SelectionDAGBuilder
...e in SelectionDAGBuilder.cpp: *case* *Intrinsic*::gcroot: *if* (GFI) { *const* Value *Alloca = I.getArgOperand(0); *const* Constant *TypeMap = cast<Constant>(I.getArgOperand(1)); * FrameIndexSDNode *FI = cast<FrameIndexSDNode>(getValue(Alloca).getNode());* GFI->addStackRoot(FI->getIndex(), TypeMap); } *return* 0; Specifically, the cast from SDNode to FrameIndexSDNode fails because the node type is DYNAMIC_STACKALLOC, while this code is expecting the node type to be "FrameIndex" or "TargetFrameIndex". (I don't know what either of the...

[LLVMdev] Cast failure in SelectionDAGBuilder
...ilder.cpp. This is the code: *case* *Intrinsic*::gcroot: *if* (GFI) { *const* Value *Alloca = I.getArgOperand(0); *const* Constant *TypeMap = cast<Constant>(I.getArgOperand(1)); * FrameIndexSDNode *FI = cast<FrameIndexSDNode>(getValue(Alloca).getNode());* GFI->addStackRoot(FI->getIndex(), TypeMap); } *return* 0 The cast<FrameIndexSDNode> is what's failing. Apparently the node isn't a FrameIndexSDNode. Now, we discussed a similar problem on this list earlier, and it was stated that the cause was due to calls to llvm.gcroot() not being in the...
