[PATCH] D102796: [SCEV] Cache operands used in BEInfo

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

This is great.
I, however, wonder if we are missing some more global caching for the `ScalarEvolution::isSCEVExprNeverPoison(const Instruction *)` itself.
For example, can we simply cache the entire result of that function?
When would it need to be invalidated?
