◆ dominanceSort()

static void dominanceSort ( SmallVector< Operation * > &  ops,
Region region,
BlockIndexCache &  blockIndexCache 

Sorts ops according to dominance.

Relies on the topological order of basic blocks to get a deterministic ordering. Uses blockIndexCache to avoid the potentially expensive recomputation of a block index map.

◆ getOrCreateBlockIndices()

static const DenseMap<Block *, size_t>& getOrCreateBlockIndices ( BlockIndexCache &  blockIndexCache,
Region region 

Gets or creates a block index mapping for region.
