[PATCH] D61105: [MS] Emit S_HEAPALLOCSITE debug info in SelectionDAG

[Amy Huang via Phabricator via llvm-commits]

akhuang added a comment.

I made some changes to keep the MDNodeSDNode attached to the call, which I mostly did by adding some special cases when operands are MDNodeSDNodes. Since call operands are currently all registers, it seems like it would be less invasive to use a map than to change the convention to include this specific MDNodeSDNode as an operand.

We also want the metadata to be dropped during tail call optimization, which would require some extra work to do here, but works with the map since the call gets replaced there.
