Add a check for the executables EI_CLASS in elf_machine_matches_host. * sysdeps/s390/elf/setjmp.S: Move to... * sysdeps/s390/s390-32/elf/setjmp.S: ...here. Replace branches to globally defined symbol __sigsetjmp by branches to a local label (this avoids the generation of a R_390_PC16DBL relocation in -fpic code). * sysdeps/s390/gmp-mparam.h: Use defines from <bits/wordsize.h> to calculate BITS_PER_MP_LIMB, BYTES_PER_MP_LIMB and BITS_PER_LONGINT. * sysdeps/s390/initfini.c: Move to... * sysdeps/s390/s390-32/initfini.c: ...here. Replace ALIGN with ".align 4,0x07". * sysdeps/s390/setjmp.S: Move to... * sysdeps/s390/s390-32/setjmp.S: ...here. Add code to store the floating point registers that should be saved according to the ABI. * sysdeps/s390/sys/ucontext.h: Remove since it is unused. * sysdeps/unix/sysv/linux/s390/sysdep.h: Move to... * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: ...here. Include sysdeps/s390/s390-32/sysdep.h instead of sysdeps/s390/sysdep.h. 2001-03-13 Martin Schwidefsky <schwidefsky@de.ibm.com> * configure.in: Change machine=s390 to machine=s390/s390-32. * elf/elf.h: Correct comment for R_390_PLT16DBL.
