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/linux/sparc/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
