Detailed Description

FunctionPassManager manages FunctionPasses and BasicBlockPassManagers.

Constructor & Destructor Documentation

◆ FunctionPassManager()

FunctionPassManager::FunctionPassManager ( Module M)
explicit

FunctionPassManager ctor - This initializes the pass manager.

Create new Function pass manager.

It needs, but does not take ownership of, the specified Module.

◆ ~FunctionPassManager()

override

Member Function Documentation

◆ add()

void FunctionPassManager::add ( Pass P)
overridevirtual

Add a pass to the queue of passes to run.

This passes ownership of the Pass to the PassManager. When the PassManager is destroyed, the pass will be destroyed as well, so there is no need to delete the pass. This may even destroy the pass right away if it is found to be redundant. This implies that all passes MUST be allocated with 'new'.

Implements llvm::legacy::PassManagerBase.

◆ doFinalization()

bool FunctionPassManager::doFinalization ( )

doFinalization - Run all of the finalizers for the function passes.

Definition at line 1399 of file LegacyPassManager.cpp.

References llvm::legacy::FunctionPassManagerImpl::doFinalization().

◆ doInitialization()

bool FunctionPassManager::doInitialization ( )

doInitialization - Run all of the initializers for the function passes.

Definition at line 1393 of file LegacyPassManager.cpp.

References llvm::legacy::FunctionPassManagerImpl::doInitialization().

◆ run()

bool FunctionPassManager::run ( Function F)

run - Execute all of the passes scheduled for execution.

Keep track of whether any of the passes modifies the function, and if so, return true.
