[PATCH] D147968: [TTI][BPF]: Undo specific transform-preventing passes and add one TTI hook

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

Considering the overall longer term maintenance cost to middle-end maintainers and the cost the BPF backend developers, this approach seems like the least intrusive method to me.  Middle end maintainers (nikic@) need to chime in if there are more concerns on the approach to unblock the progress.  The assumption is that more longer term solution will be explored further (e.g. legalization, or maintaining range info etc).
