Problem is that gcc 3.1 > does not allow the address of a label to be used outside the function > where the label is defined. The second problem is a race condition in linuxthreads. This is fixed with the memory barrier definition. The patch for the two problems: 2002-01-16 Martin Schwidefsky <schwidefsky@de.ibm.com> * linuxthreads/sysdeps/s390/s390-32/pt-machine.h: (MEMORY_BARRIER): Define. (CURRENT_STACK_FRAME): Remove duplicate definition. * linuxthreads/sysdeps/s390/s390-64/pt-machine.h: Likewise. * sysdeps/unix/sysv/linux/s390/swapcontext.c: Remove. * sysdeps/unix/sysv/linux/s390/s390-32/swapcontext.S: New file. * sysdeps/unix/sysv/linux/s390/s390-64/swapcontext.S: New file. (See attached file: glibc-2.2.5pre1-s390-3.diff) I hope that this is it now. Make tests runs without problem with gcc 2.95.3, we'll have the result with gcc 3.1 by tomorrow. blue skies, Martin Linux/390 Design & Development, IBM Deutschland Entwicklung GmbH Schönaicherstr. 220, D-71032 Böblingen, Telefon: 49 - (0)7031 - 16-2247 E-Mail: schwidefsky@de.ibm.com
