[LLVMdev] FoldingSetNodeID operations inefficiency
...called from the
SelectionDAGLowering::visitStore).
During the code selection phase, the SelectionDAG::ReplaceAllUsesWith is
called many times and in many cases it tried to update this node, by
replacing some of its 3200 operands by a different operand. After each
such operand replacement, this snippen of code is typically executed
(see SelectionDAG.cpp):
// Now that we have modified U, add it back to the CSE maps.
// If it already exists there, recursively merge the results together.
if (SDNode *Existing = AddNonLeafNodeToCSEMaps(U)) {
ReplaceAllUsesWith(U, Existing, UpdateListener);...
