It looks like Steven is working on things clang, including LTO. On the Xcode/clang side there is a linker flag, -object_path_lto $(DEST_DIR_DEBUG)/$(BASE_NAME).lto, that needs to get added to store temp output of the LTO generation to support debug, but there is not a compiler flag required. The Xcode clang flags are very GCC like, but the linker is totally different. Thanks, Andrew Fish > Indeed.
