Lu via Gcc-patches" From: "H.J. Lu" Reply-To: "H.J. Lu" Cc: gcc-patches@gcc.gnu.org Errors-To: gcc-patches-bounces@gcc.gnu.org Sender: "Gcc-patches" Add the --enable-pgo-build[=lto] configure option. When binutils+gdb is not built together with GCC, --enable-pgo-build enables the PGO build: 1. First build with -fprofile-generate. 2. Use "make maybe-check-*" to generate profiling data. 3. Use "make clean" to remove the previous build. 4. Rebuild with -fprofile-use. With --enable-pgo-build=lto, -flto=jobserver is used together with -fprofile-generate and -fprofile-use. Add '+' to the command line for recursive make to support -flto=jobserver. NB: --enable-pgo-build=lto enables the PGO build with LTO while --enable-lto enables LTO support in toolchain.
