This templated class represents "all analyses that operate over <a particular IR unit>" (e....
API to communicate dependencies between analyses during invalidation.
A container for analyses that lazily runs them and caches their results.
PassT::Result & getResult(IRUnitT &IR, ExtraArgTs... ExtraArgs)
Get the result of an analysis pass for a given IR unit.
Represent the analysis usage information of a pass.
AnalysisUsage & addRequired()
void setPreservesAll()
Set by analyses that do not transform their input at all.
Represents analyses that only rely on functions' control flow.
Analysis pass which computes a DominanceFrontier.
DominanceFrontier run(Function &F, FunctionAnalysisManager &AM)
