1997-08-11 11:58  Richard Henderson  <rth@cygnus.com>

	Sparc64 merge:
	* configure.in: Change up subdirectories, rename sparc8->sparcv8.

	* csu/Makefile: Nuke need-nopic-initfini bits.  The problem was
	that sparc64 ld did not recognize pic relocs at all.

	* elf/dl-deps.c: Include <string.h>.
	* elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size
	directly instead of the DT names to get them from.
	* elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled
	from ELF_DYNAMIC_DO_REL{,A}.  Define a second version that accounts
	for the possibility that DT_RELA and DT_JMPPLT overlap, as such is
	the case on the Sparc.

	* elf/elf.h: Stub out Elf64_Ver*, and make them the same as the
	Elf32_Ver* bits.  The linker does not even know to differentiate
	between the word sizes.  Someone should examine this and figure
	out what the proper sizes of things should be for 64-bit hosts
	before the sparc64 libraries are distributed.

	* shlib-versions: Rename sparc64 ld.so to not conflict with sparc32
	on the same machine.

	Move old sysdeps/sparc contents to sysdeps/sparc/sparc32,
	rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to
	sysdeps/sparc/sparc64.  Same for sysdeps/unix/sysv/linux/sparc.

	* sysdeps/sparc/Implies: Do ieee754 here.
	* sysdeps/sparc/configure.in: Move from sparc32/.
	* sysdeps/sparc/sparc32/Implies: Do wordsize here.
	* sysdeps/sparc/sparc64/Implies: Likewise.

	* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_load_address):
	Use uninitialized .got to find load address instead of AT_BASE, as
	the later does not exist when running ld.so directly.

	* sysdeps/sparc/sparc32/fpu/fpu_control.h: Move from ../.
	* sysdeps/sparc/sparc64/fpu/fpu_control.h: Likewise.

	* sysdeps/sparc/sparc32/udiv_qrnnd.S: Clean up PIC support.

	* sysdeps/sparc/sparc64/Makefile (sysdep_routines): Add s_finitel
	and s_signbitl for stdio.
	* sysdeps/sparc/sparc64/configure.in: Remove, we no longer need
	nopic_initfini.

	* sysdeps/sparc/sparc64/bsd-_setjmp.S: Remove.
	* sysdeps/sparc/sparc64/bsd-setjmp.S: Remove.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bsd-_setjmp.S: New empty file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bsd-setjmp.S: New empty file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/longjmp.S: Add __longjmp alias.
	* sysdeps/unix/sysv/linux/sparc/sparc64/setjmp.S: Add weak _setjmp
	and setjmp entry points.

	* sysdeps/sparc/sparc64/dl-machine.h: Finish real implementation.

	* sysdeps/sparc/sparc64/elf/crtbegin.S: Add copyright, fix PIC.
	* sysdeps/sparc/sparc64/elf/crtend.S: Likewise.

	* sysdeps/unix/sysv/linux/sparc/bits/sigaction.h (struct sigaction):
	Fix sa_flags size for sparc64; add sa_restorer for kernel.

	* sysdeps/unix/sysv/linux/sparc/sparc64/brk.S: Fix PIC.
	* sysdeps/unix/sysv/linux/sparc/sparc64/clone.S: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/init-first.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise.

	* sysdeps/unix/sysv/linux/sparc/sparc64/syscall.S: New file.

1997-08-10 18:29:08 1997  Mark Kettenis  <kettenis@phys.uva.nl>

	* login/login.c (login): Check for correct return value of
	utmpname.

1997-08-11 16:49  Ulrich Drepper  <drepper@cygnus.com>

	* time/tzset.c (__tzset_internal): Correctly handle TZ strings
	following incorrect old POSIX specs.
	Patch by Paul Eggert <eggert@twinsun.com>.

	* sysdeps/generic/bits/sigaction.h: Correct comment for SA_RESTART.
	* sysdeps/unix/bsd/osf/bits/sigaction.h: Likewise.
	* sysdeps/unix/sysv/linux/alpha/bits/sigaction.h: Likewise.
	* sysdeps/unix/sysv/linux/bits/sigaction.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/sigaction.h: Likewise.

	* sysdeps/unix/sysv/minix/bits/sigaction.h: Likewise.
	* sysdeps/unix/sysv/sysv4/bits/sigaction.h: Likewise.
	Reported by NIIBE Yutaka <gniibe@mri.co.jp>.

1997-08-09  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* manual/math.texi: Define the macros @mul and @infinity and use
	them to format the multiplication and infinity signs.
	(FP Comparison Functions): Use @code, not @math, for C code
	examples.

	* elf/dl-profile.c: Add descriptions and implement reading of
