--- Comment #3 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- (In reply to Jonathan Wakely from comment #2) > Why have these symbols appeared now? Is TLS enabled by default on this > target now? Did something change regarding TLS? Not that I know of. > Are you using the default configuration? The configuration we always use for testing, minus some languages. $ configure --with-arch=zEC12 --enable-languages=c,c++ --enable-bootstrap --enable-multilib --disable-checking --enable-checking=none --enable-shared --with-system-zlib --enable-threads=posix --enable-__cxa_atexit --enable-gnu-indirect-function (The --enable-shared is left over from an earlier experiment, but that should not matter, or does it?)
