Member Functions

Name	Description
`LTOCodeGenerator` [constructor]	Construct an LTO code generator that uses the given LLVM context.
`~LTOCodeGenerator` [destructor]	Destroy this LTO code generator.
`DiagnosticHandler`	Forward an LLVM diagnostic to the external LTO diagnostic handler.
`addModule`	Merge given module. Return true on success.
`addMustPreserveSymbol`	Record a symbol that must be preserved during LTO.
`compile`	Optimize and compile the merged module into a single in-memory buffer.
`compileOptimized`	`compileOptimized` overloads
`compile_to_file`	Compile the merged module into a single output file; the path to output file is returned to the caller via argument "name". Return true on success.
`getContext`	Return the LLVM context used by this code generator.
`optimize`	Optimizes the merged module. Returns true on success.
`parseCodeGenDebugOptions`	Parse the options set in setCodeGenDebugOptions.
`resetMergedModule`	Destroy the merged module, releasing ownership of it.
`setAsmUndefinedRefs`	Record assembly undefined references from the given module.
`setAttrs`	Set the target feature attributes for code generation.
`setCodeGenDebugOptions`	Pass options to the driver and optimization passes.
`setCodePICModel`	Set the relocation model for code generation.
`setCpu`	Set the target CPU name for code generation.
`setDebugInfo`	Set the debug-info model to emit.
`setDebugPassManager`	Enable or disable debug output from the pass manager.
`setDiagnosticHandler`	Set the external diagnostic handler callback and its context.
`setDisableVerify`	Enable or disable IR verification during LTO.
`setFileType`	Set the file type to be emitted (assembly or object code). The default is CodeGenFileType::ObjectFile.
`setFreestanding`	Enable the Freestanding mode: indicate that the optimizer should not assume builtins are present on the target.
`setModule`	Set the destination module.
`setOptLevel`	Set the optimization level used for LTO and code generation.
`setSaveIRBeforeOptPath`	Set the path where IR is saved before optimization, if any.
`setShouldEmbedUselists`	Set whether to embed use-lists when writing bitcode.
`setShouldInternalize`	Set whether LTO should internalize unreferenced globals.
`setShouldRestoreGlobalsLinkage`	Restore linkage of globals
`setTargetOptions`	Set the target options used for code generation.
`writeMergedModules`	Write the merged module to the file specified by the given path. Return true on success.

Static Member Functions

Name	Description
`getVersionString`	Return a string identifying the LTO library version.
