PreservedAnalyses run(Function &F, FunctionAnalysisManager &AM)
A set of analyses that are preserved following a run of a transformation pass.
static PreservedAnalyses all()
Construct a special preserved set that preserves all passes.
Enumerate the SCCs of a directed graph in reverse topological order of the SCC DAG.
This is an optimization pass for GlobalISel generic memory operations.
