	* 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.

+/* How profiling works on 64 bit S/390:
+   On the start of each function _mcount is called with the address of a
+   data word in %r1 (initialized to 0, used for counting). The compiler
+   with the option -p generates code of the form:
+  
+           STM    6,15,24(15)
+           BRAS   13,.LTN0_0
+   .LT0_0: 
+   .LC13:  .long  .LP0
+           .data
+           .align 4
+   .LP0:   .long  0
+           .text
+   # function profiler
+           stg    14,4(15)
+           lg     1,.LC13-.LT0_0(13)
+           brasl  14,_mcount
+           lg     14,4(15)
+  
+   The _mcount implementation now has to call __mcount_internal with the
+   address of .LP0 as first parameter and the return address as second
+   parameter. &.LP0 was loaded to %r1 and the return address is in %r14.
+   _mcount may not modify any register.  */
