Constructor & Destructor Documentation

◆ PredecessorAnalysis()

llzk::PredecessorAnalysis::PredecessorAnalysis ( DataFlowSolver & s,
raw_ostream & ro )
inline

Definition at line 136 of file PredecessorAnalysisPass.cpp.

Member Function Documentation

◆ setToEntryState()

void llzk::PredecessorAnalysis::setToEntryState ( PredecessorLattice * lattice)
inlineoverrideprotected

Definition at line 197 of file PredecessorAnalysisPass.cpp.

◆ visitCallControlFlowTransfer()

void llzk::PredecessorAnalysis::visitCallControlFlowTransfer ( CallOpInterface call,
mlir::dataflow::CallControlFlowAction action,
const PredecessorLattice & before,
PredecessorLattice * after )
inlineoverride

action == CallControlFlowAction::Enter indicates that:

  • before is the state before the call operation;
  • after is the state at the beginning of the callee entry block;

action == CallControlFlowAction::Exit indicates that:

  • before is the state at the end of a callee exit block;
  • after is the state after the call operation.

action == CallControlFlowAction::External indicates that:

  • before is the state before the call operation.
  • after is the state after the call operation, since there is no callee body to enter into.
