Function Documentation

LLVMPassManagerRef LLVMCreateFunctionPassManager

(

LLVMModuleProviderRef

MP

)

Constructs a new function-by-function pass pipeline over the module provider. It does not take ownership of the module provider. This type of pipeline is suitable for code generation and JIT compilation tasks. See llvm::FunctionPassManager::FunctionPassManager.

Definition at line 1687 of file PassManager.cpp.

LLVMPassManagerRef LLVMCreatePassManager

(

void

)

Constructs a new whole-module pass pipeline. This type of pipeline is suitable for link-time optimization and whole-module transformations. See llvm::PassManager::PassManager.

Definition at line 1683 of file PassManager.cpp.

void LLVMDisposePassManager

(

LLVMPassManagerRef

PM

)

Frees the memory of a pass pipeline. For function pipelines, does not free the module provider. See llvm::PassManagerBase::~PassManagerBase.

Definition at line 1707 of file PassManager.cpp.

int LLVMFinalizeFunctionPassManager

(

LLVMPassManagerRef

FPM

)

Finalizes all of the function passes scheduled in in the function pass manager. Returns 1 if any of the passes modified the module, 0 otherwise. See llvm::FunctionPassManager::doFinalization.

Definition at line 1703 of file PassManager.cpp.

int LLVMInitializeFunctionPassManager

(

LLVMPassManagerRef

FPM

)

Initializes all of the function passes scheduled in the function pass manager. Returns 1 if any of the passes modified the module, 0 otherwise. See llvm::FunctionPassManager::doInitialization.

Definition at line 1695 of file PassManager.cpp.

int LLVMRunFunctionPassManager	(	LLVMPassManagerRef	FPM,
		LLVMValueRef	F
	)

Executes all of the function passes scheduled in the function pass manager on the provided function. Returns 1 if any of the passes modified the function, false otherwise. See llvm::FunctionPassManager::run(Function&).

Definition at line 1699 of file PassManager.cpp.

int LLVMRunPassManager	(	LLVMPassManagerRef	PM,
		LLVMModuleRef	M
	)

Initializes, executes on the provided module, and finalizes all of the passes scheduled in the pass manager. Returns 1 if any of the passes modified the module, 0 otherwise. See llvm::PassManager::run(Module&).

Definition at line 1691 of file PassManager.cpp.

void StartPassTimer

(

Pass *
