I extended -Bsymbolic-functions to libffi, libjava, libmudflap, libssp and libgcc. There are no regressions: http://gcc.gnu.org/ml/gcc-testresults/2007-01/msg00511.html http://gcc.gnu.org/ml/gcc-testresults/2007-01/msg00510.html http://gcc.gnu.org/ml/gcc-testresults/2007-01/msg00509.html If we apply -Bsymbolic-functions to all shared libraries on a system, it will improve application startup time and overall runtime performance.
