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()

Definition at line 251 of file DynamicLibrary.cpp.

References llvm::sys::DynamicLibrary::AddSymbol().

◆ LLVMCreateMessage()

char * LLVMCreateMessage ( const char * Message )

Definition at line 82 of file Core.cpp.

Referenced by LLVMGetDiagInfoDescription().

◆ LLVMDisposeMessage()

void LLVMDisposeMessage ( char * Message )

Definition at line 86 of file Core.cpp.

◆ 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.

Definition at line 71 of file Core.cpp.

◆ 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()

Definition at line 243 of file DynamicLibrary.cpp.

References llvm::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()

Definition at line 2834 of file CommandLine.cpp.

References llvm::nulls(), and 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()

Definition at line 247 of file DynamicLibrary.cpp.

References llvm::sys::DynamicLibrary::SearchForAddressOfSymbol().

◆ LLVMShutdown()

void LLVMShutdown ( void )

Deallocate and destroy all ManagedStatic variables.

See also: llvm::llvm_shutdown; ManagedStatic

Definition at line 65 of file Core.cpp.

References llvm::llvm_shutdown().
