Detailed Description

PassManagerImpl manages MPPassManagers.

Definition at line 385 of file LegacyPassManager.cpp.

Member Function Documentation

◆ add()

void llvm::legacy::PassManagerImpl::add ( Pass P)
inline

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'.

Definition at line 397 of file LegacyPassManager.cpp.

◆ createPrinterPass()

Pass* llvm::legacy::PassManagerImpl::createPrinterPass ( raw_ostream O,
const std::string &  Banner 
) const
inlineoverridevirtual

createPrinterPass - Get a module printer pass.

Implements llvm::Pass.

Definition at line 402 of file LegacyPassManager.cpp.

References llvm::createPrintModulePass(), llvm::Pass::doFinalization(), and llvm::Pass::doInitialization().

◆ getAnalysisUsage()

void llvm::legacy::PassManagerImpl::getAnalysisUsage ( AnalysisUsage Info) const
inlineoverridevirtual

Pass Manager itself does not invalidate any analysis info.

Reimplemented from llvm::Pass.

Definition at line 415 of file LegacyPassManager.cpp.

References llvm::AnalysisUsage::setPreservesAll().

◆ getAsPass()

Pass* llvm::legacy::PassManagerImpl::getAsPass ( )
inlineoverridevirtual

Implements llvm::PMDataManager.

Definition at line 420 of file LegacyPassManager.cpp.

◆ getAsPMDataManager()

PMDataManager* llvm::legacy::PassManagerImpl::getAsPMDataManager ( )
inlineoverridevirtual

Implements llvm::PMTopLevelManager.

Definition at line 419 of file LegacyPassManager.cpp.

MPPassManager* llvm::legacy::PassManagerImpl::getContainedManager ( unsigned  N)
inline

◆ getTopLevelPassManagerType()

PassManagerType llvm::legacy::PassManagerImpl::getTopLevelPassManagerType ( )
inlineoverridevirtual

Implements llvm::PMTopLevelManager.

Definition at line 421 of file LegacyPassManager.cpp.

References llvm::PMT_ModulePassManager.

◆ run()

bool PassManagerImpl::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.
