[PATCH] D76273: [NFCI][SCEV] Avoid recursion in SCEVExpander::isHighCostExpansion*()

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

As a suggestion: since this helper doesn't create new code, it doesn't seem to be important whether it is FIFO or LIFO. If that is so, I'd suggest using SmallVector and LIFO algorithm instead. It should have better memory footprint. OK if it does as follow-up.
