Module llvm_sys::lto [] [src]

Abstract link time optimization.

ThinLTO

ThinLTO is designed to do LTO while requiring fewer resources than regular LTO. It can run much faster and in less memory (comparable to linking without LTO) than regular LTO, with essentially no loss in optimization.

Structs

LTOObjectBuffer

Type to wrap a single object returned by ThinLTO.

Functions

lto_api_version

Returns the runtime API version.

lto_codegen_add_module
lto_codegen_add_must_preserve_symbol
lto_codegen_compile
lto_codegen_compile_optimized

Generates code for the optimized merged module into one native object file.

lto_codegen_compile_to_file
lto_codegen_create

Returns the module's linker options.

lto_module_get_num_symbols
lto_module_get_symbol_attribute
lto_module_get_symbol_name
lto_module_get_target_triple
lto_module_has_objc_category

Return true if Buffer contains a bitcode file with ObjC code (category or class) in it.

lto_module_is_object_file
lto_module_is_object_file_for_target
lto_module_is_object_file_in_memory

Checks if a buffer is a loadable object file.

lto_module_is_object_file_in_memory_for_target
lto_module_is_thinlto

Test if a module has ThinLTO linking support.
