Member Enumeration Documentation

KindTy

enum llvm::instrumentor::InstrumentationLocation::KindTy

The supported location kinds, which are composed of a opportunity type and position.

The PRE position indicates the instrumentation function call is inserted before the instrumented event occurs. The POST position indicates the instrumentation call is inserted after the event occurs. Some opportunity types may only support one position.
