Method to try and mark a result as invalid.
When the outer analysis manager detects a change in some underlying unit of the IR, it will call this method on all of the results cached.
PA
is a set of preserved analyses which can be used to avoid invalidation because the pass which changed the underlying IR took care to update or preserve the analysis result in some way.
Inv
is typically a AnalysisManager::Invalidator
object that can be used by a particular analysis result to discover if other analyses results are also invalidated in the event that this result depends on them. See the documentation in the AnalysisManager
for more details.
Implemented in llvm::detail::AnalysisResultModel< IRUnitT, PassT, ResultT, InvalidatorT, false >, and llvm::detail::AnalysisResultModel< IRUnitT, PassT, ResultT, InvalidatorT, true >.
