Hi! We currently bootstrap both libsanitizer and libvtv, the former just in case somebody decides to --with-build-config=bootstrap-asan (or --with-build-config=bootstrap-ubsan), the latter if somebody decides to --enable-vtable-verify.
This patch changes it so that we only bootstrap libsanitizer if bootstrap-asan or bootstrap-ubsan is in BOOT_CONFIG, and only bootstrap libvtv if --enable-vtable-verify. Bootstrapped/regtested on x86_64-linux and i686-linux, on x86_64 it saved a few minutes of build time, neither libsanitizer nor libvtv has been bootstrapped, only built in stage3. Currently also bootstrapping on i686-linux with --enable-vtable-verify --with-build-config=bootstrap-asan but already got into stage2 and verified that both libsanitizer and libvtv are being bootstrapped in that case. Ok for trunk? 2014-03-20 Jakub Jelinek <ja...@redhat.com> * configure.ac: Move BUILD_CONFIG set up earlier. Add --enable-vtable-verify option parsing. Don't add target-libsanitizer to bootstrap_target_libs unless --with-build-config=bootstrap-asan or --with-build-config=bootstrap-ubsan. Don't add target-libvtv to bootstrap_target_libs unless --enable-vtable-verify. * configure: Regenerated. --- configure.ac.jj 2014-03-03 08:24:36.000000000 +0100 +++ configure.ac 2014-03-20 09:47:17.676017039 +0100 @@ -2472,6 +2472,62 @@ else GCC_SHLIB_SUBDIR= fi +# Adjust the toplevel makefile according to whether bootstrap was selected. +case $enable_bootstrap in + yes) + bootstrap_suffix=bootstrap + BUILD_CONFIG=bootstrap-debug + ;;
