	* configure.in: Add support for 64 bit S/390.

	* elf/elf.h: Add new relocations for 64 bit S/390.

	* shlib-versions: Add rules for Linux on 64 bit S/390.

2001-03-13  Martin Schwidefsky  <schwidefsky@de.ibm.com>

	* sysdeps/s390/__longjmp.c: Move to...
	* sysdeps/s390/s390-32/__longjmp.c: ...here.  Add code
	to load the floating point registers that should be saved
	according to the ABI.

	* sysdeps/s390/bits/setjmp.h: Move to...
	* sysdeps/s390/s390-32/bits/setjmp.h: ...here.  Avoid
	the use of long long in the __jmp_buf type definition.

	* sysdeps/s390/bits/string.h: Move to...
	* sysdeps/s390/s390-32/bits/string.h: ...here.  Add several missing
	#ifndef _FORCE_INLINES.

	* sysdeps/s390/dl-machine.h: Move to...
	* sysdeps/s390/s390-32/dl-machine.h: ...here.  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.

* scripts/config.guess: Add support for Linux on 64 bit S/390.
* scripts/config.sub: Likewise.
2001-03-13 Martin Schwidefsky <schwidefsky@de.ibm.com>
* configure.in: Add support for 64 bit S/390.
* elf/elf.h: Add new relocations for 64 bit S/390.
* shlib-versions: Add rules for Linux on 64 bit S/390.

* sysdeps/s390/__longjmp.c: Move to...
* sysdeps/s390/s390-32/__longjmp.c: ...here. Add code
to load the floating point registers that should be saved
according to the ABI.
* sysdeps/s390/bits/setjmp.h: Move to...
* sysdeps/s390/s390-32/bits/setjmp.h: ...here. Avoid
the use of long long in the __jmp_buf type definition.

* 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.
