¶double calcExtTspScore(
    const std::vector<uint64_t>& Order,
    const std::vector<uint64_t>& NodeSizes,
    const std::vector<uint64_t>& NodeCounts,
    const DenseMap<std::pair<uint64_t, uint64_t>,

Description

Estimate the "quality" of a given node order in CFG. The higher the score, the better the order is. The score is designed to reflect the locality of the given order, which is anti-correlated with the number of I-cache misses in a typical execution of the function.
