[PATCH] D61810: [BPF] add new intrinsics preserve_{array,union,struct}_access_index

[Yonghong Song via Phabricator via llvm-commits]

yonghong-song added a comment.

@lebedev.ri For comments "What about other targets, does this need some default expansion?",  currently these intrinsics only used by bpf and lowered to GEP in an IR pass implemented by bpf backend. I can certainly implement some default expansion if it is desirable. Is the SelectionDAG the proper place to implement the default lowering?
