Detailed Description

template<class IntPtrT>
class llvm::RawInstrProfReader< IntPtrT >

Reader for the raw instrprof binary format from runtime.

This format is a raw memory dump of the instrumentation-baed profiling data from the runtime. It has no index.

Templated on the unsigned type whose size matches pointers on the platform that wrote the profile.
