findCommonDominator()

template<typename DominatorT >

static Block* mlir::bufferization::BufferPlacementTransformationBase::findCommonDominator ( Value  value, const ValueSetT &  values, const DominatorT &  doms  )

inlinestatic

Finds a common dominator for the given value while taking the positions of the values in the value set into account.

It supports dominator and post-dominator analyses via template arguments.

isLoop()

bool BufferPlacementTransformationBase::isLoop ( Operation *  op )

static

Returns true if the given operation represents a loop by testing whether it implements the LoopLikeOpInterface or the RegionBranchOpInterface.

In the case of a RegionBranchOpInterface, it checks all region-based control-flow edges for cycles.

In the case of a RegionBranchOpInterface, it checks all region-based control- flow edges for cycles.
