void * llvm::RuntimeDyld::getSymbolAddress

(

StringRef

Name

)

const

Get the address of our local copy of the symbol. This may or may not be the address used for relocation (clients can copy the data around and resolve relocatons based on where they put it).

uint64_t llvm::RuntimeDyld::getSymbolLoadAddress

(

StringRef

Name

)

const

Get the address of the target copy of the symbol. This is the address used for relocation.

std::unique_ptr< ObjectImage > llvm::RuntimeDyld::loadObject

(

std::unique_ptr< ObjectBuffer >

InputBuffer

)

Prepare the object contained in the input buffer for execution. Ownership of the input buffer is transferred to the ObjectImage instance returned from this function if successful. In the case of load failure, the input buffer will be deleted.

(

std::unique_ptr< object::ObjectFile >

InputObject

)

Prepare the referenced object file for execution. Ownership of the input object is transferred to the ObjectImage instance returned from this function if successful. In the case of load failure, the input object will be deleted.

void llvm::RuntimeDyld::mapSectionAddress	(	const void *	LocalAddress,
		uint64_t	TargetAddress
	)

Map a section to its target address space value. Map the address of a JIT section as returned from the memory manager to the address in the target process as the running code will see it. This is the address which will be used for relocation resolution.

void llvm::RuntimeDyld::registerEHFrames

(

)

Register any EH frame sections that have been loaded but not previously registered with the memory manager. Note, RuntimeDyld is responsible for identifying the EH frame and calling the memory manager with the EH frame section data. However, the memory manager itself will handle the actual target-specific EH frame registration.

void llvm::RuntimeDyld::resolveRelocations

(

)

Resolve the relocations for all symbols we currently know about.

void llvm::RuntimeDyld::setProcessAllSections

(

bool

ProcessAllSections

)

[inline]

By default, only sections that are "required for execution" are passed to the RTDyldMemoryManager, and other sections are discarded. Passing 'true' to this method will cause RuntimeDyld to pass all sections to its memory manager regardless of whether they are "required to execute" in the usual sense. This is useful for inspecting metadata sections that may not contain relocations, E.g. Debug info, stackmaps.

Must be called before the first object file is loaded.
