Member Function Documentation

◆ add()

void llvm::InstructionWorklist::add ( Instruction I)
inline

Add instruction to the worklist.

Instructions will be visited in the order they are added. You likely want to use this method.

Definition at line 44 of file InstructionWorklist.h.

References llvm::dbgs(), I, llvm::SetVector< T, SmallVector< T, N >, SmallDenseSet< T, N > >::insert(), and LLVM_DEBUG.

Referenced by addValue(), and combineInstructionsOverFunction().

◆ addValue()

void llvm::InstructionWorklist::addValue ( Value V)
inline

Add value to the worklist if it is an instruction.

Instructions will be visited in the order they are added.

Definition at line 51 of file InstructionWorklist.h.

References add(), and I.

◆ isEmpty()

bool llvm::InstructionWorklist::isEmpty ( ) const
inline

◆ operator=()

InstructionWorklist& llvm::InstructionWorklist::operator= ( InstructionWorklist &&  )
default

◆ popDeferred()

Instruction* llvm::InstructionWorklist::popDeferred ( )
inline

◆ push()

void llvm::InstructionWorklist::push ( Instruction I)
inline

◆ pushUsersToWorkList()

void llvm::InstructionWorklist::pushUsersToWorkList ( Instruction I)
inline

When an instruction is simplified, add all users of the instruction to the work lists because they might get more simplified now.

Definition at line 106 of file InstructionWorklist.h.

◆ pushValue()

void llvm::InstructionWorklist::pushValue ( Value V)
inline

◆ remove()

void llvm::InstructionWorklist::remove ( Instruction I)
inline

◆ removeOne()
