Detailed Description

This modules provide an interface to libLLVMCore, which implements the LLVM intermediate representation as well as other related types and utilities.

Many exotic languages can interoperate with C code but have a harder time with C++ due to name mangling. So in addition to C, this interface enables tools written in such languages.

Function Documentation

LLVMAddSymbol()

void LLVMAddSymbol	(	const char *	symbolName,
		void *	symbolValue
	)

This functions permanently adds the symbol symbolName with the value symbolValue. These symbols are searched before any libraries.

See also

sys::DynamicLibrary::AddSymbol()

LLVMCreateMessage()

char * LLVMCreateMessage

(

const char *

Message

)

LLVMDisposeMessage()

void LLVMDisposeMessage

(

char *

Message

)

Here is the caller graph for this function:

LLVMGetVersion()

void LLVMGetVersion	(	unsigned *	Major,
		unsigned *	Minor,
		unsigned *	Patch
	)

Return the major, minor, and patch version of LLVM

The version components are returned via the function's three output parameters or skipped if a NULL pointer was supplied.

LLVMLoadLibraryPermanently()

LLVMBool LLVMLoadLibraryPermanently

(

const char *

Filename

)

This function permanently loads the dynamic library at the given path. It is safe to call this function multiple times for the same library.

See also

sys::DynamicLibrary::LoadLibraryPermanently()

LLVMParseCommandLineOptions()

void LLVMParseCommandLineOptions	(	int	argc,
		const char *const *	argv,
		const char *	Overview
	)

This function parses the given arguments using the LLVM command line parser. Note that the only stable thing about this function is its signature; you cannot rely on any particular set of command line arguments being interpreted the same way across LLVM versions.

See also

llvm::cl::ParseCommandLineOptions()

LLVMSearchForAddressOfSymbol()

void * LLVMSearchForAddressOfSymbol

(

const char *

symbolName

)

This function will search through all previously loaded dynamic libraries for the symbol symbolName. If it is found, the address of that symbol is returned. If not, null is returned.

See also

sys::DynamicLibrary::SearchForAddressOfSymbol()

LLVMShutdown()

void LLVMShutdown

(

void

)

Deallocate and destroy all ManagedStatic variables.
