StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:55
This class implements an extremely fast bulk output stream that can only output to a stream.
Definition: raw_ostream.h:53
A pass that runs on a sandbox::Function.

\Returns the name of the pass.

void printPipeline(raw_ostream &OS) const final
Similar to print() but adds a newline. Used for testing.
bool runOnFunction(Function &F, const Analyses &A) final
\Returns true if it modifies F.
