Hi, I could successfully bootstrap the dataflow branch on s390 and s390x.
Configure options: --enable-shared --with-system-zlib --enable-threads=posix --enable-__cxa_atexit --enable-checking --enable-languages=c,c++,fortran,java,objc No testsuite regressions occurred comparing dataflow branch rev. 120826 on s390 and s390x with mainline rev. 120219. Bye, -Andreas-
