Content
LTO exists in GCC since version 4.5, but it is true that only recent versions (>=4.8) perform it in good conditions. It is not enabled by default in this patch, it is only available when building with PGO support. Running just "make" will not activate the LTO flags. Do you see it as an configure option (using, for example, an explicit --with-lto flag) rather than using it automatically?
