--- Comment #3 from Michael Meissner <meissner at gcc dot gnu.org> --- I just built a toolchain on gcc2-power8.osuosl.org with the configuration line: /home/meissner/fsf-src/trunk/configure --prefix=/home/meissner/fsf-install-ppcle64/trunk --enable-languages=c,c++,ada,fortran,java,objc,obj-c++ --with-long-double-128 --enable-secureplt --enable-__cxa_atexit --disable-libsanitizer --with-cpu=power8 And after doing a make check, install, and check, I did not see any of these tests generate errors with -flto -fuse-linker-plugin -flto-partition=none. What was the exact command line you used to configure the compiler, and what was your path?
