Detailed Description

PassManager manages ModulePassManagers.

Constructor & Destructor Documentation

◆ PassManager()

llvm::legacy::PassManager::PassManager ( )

Create new pass manager.

Definition at line 1667 of file LegacyPassManager.cpp.

References llvm::PMDataManager::setTopLevelManager().

◆ ~PassManager()

llvm::legacy::PassManager::~PassManager ( )

Definition at line 1673 of file LegacyPassManager.cpp.

Member Function Documentation

◆ add()

void llvm::legacy::PassManager::add ( Pass P)

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.

Reimplemented in llvm::DebugifyCustomPassManager.

Definition at line 1677 of file LegacyPassManager.cpp.

References llvm::legacy::PassManagerImpl::add(), and P.

Referenced by llvm::DebugifyCustomPassManager::add(), and codegen().

◆ run()

bool llvm::legacy::PassManager::run ( Module M)

run - Execute all of the passes scheduled for execution.

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

Definition at line 1683 of file LegacyPassManager.cpp.
