I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...

It seems that some gcc versions might generates a stack frame for the
sigreturn stub requires on sparc signal handling. For instance:
$ cat test.c
#define _GNU_SOURCE
#include <sys/syscall.h>
__attribute__ ((__optimize__ ("-fno-stack-protector")))
void
__sigreturn_stub (void)
{
__asm__ ("mov %0, %%g1\n\t"
"ta 0x10\n\t"
: /* no outputs */
: "i" (SYS_rt_sigreturn));
}
$ gcc -v
[...]
gcc version 9.2.1 20200224 (Debian 9.2.1-30)
$ gcc -O2 -m64 test.c -S -o -
[...]
__sigreturn_stub:
save %sp, -176, %sp
#APP
! 9 "t.c" 1
mov 101, %g1
ta 0x10
! 0 "" 2
#NO_APP
.size __sigreturn_stub, .-__sigreturn_stub
As indicated by kernel developers [1], the sigreturn stub can not change
the register window or the stack pointer since the kernel has setup the
restore frame at a precise location relative to the stack pointer when
the stub is invoked.
I tried to play with some compiler flags and even with _Noreturn and
__builtin_unreachable after the asm does not help (and Sparc does not
support naked functions).
To avoid similar issues, as the stack-protector support also have
stumbled, this patch moves the implementation of the sigreturn stubs to
assembly.
Checked on sparcv9-linux-gnu and sparc64-linux-gnu with gcc 9.2.1
and gcc 7.5.0.

Alpha rt_sigaction syscall uses a slight different kernel ABI than
generic one:
arch/alpha/kernel/signal.c
90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act,
91 struct sigaction __user *, oact,
92 size_t, sigsetsize, void __user *, restorer)
Similar as sparc, the syscall expects a restorer function. However
different than sparc, alpha defines the restorer as the 5th argument
(sparc defines as the 4th).
This patch removes the arch-specific alpha sigaction implementation,
adapt the Linux generic one to different restore placements (through
STUB macro), and make alpha use the Linux generic kernel_sigaction
definition.
Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity).

This patch consolidates all Linux sigaction implementations on the default
sysdeps/unix/sysv/linux/sigaction.c. The idea is remove redundant code
and simplify new ports addition by following the current generic
Linux User API (UAPI).
The UAPI for new ports defines a generic extensible sigaction struct as:
struct sigaction
{
__sighandler_t sa_handler;
unsigned long sa_flags;
#ifdef SA_RESTORER
void (*sa_restorer) (void);
#endif
sigset_t sa_mask;
};
Where SA_RESTORER is just placed for compatibility reasons (news ports
should not add it). A similar definition is used on generic
kernel_sigaction.h.
The user exported sigaction definition is not changed, so for most
architectures it requires an adjustment to kernel expected one for the
syscall.
The main changes are:
- All architectures now define and use a kernel_sigaction struct meant
for the syscall, even for the architectures where the user sigaction
has the same layout of the kernel expected one (s390-64 and ia64).
Although it requires more work for these architectures, it simplifies
the generic implementation. Also, sigaction is hardly a hotspot where
micro optimization would play an important role.
- The generic kernel_sigaction definition is now aligned with expected
UAPI one for newer ports, where SA_RESTORER and sa_restorer are not
expected to be defined. This means adding kernel_sigaction for
current architectures that does define it (m68k, nios2, powerpc, s390,
sh, sparc, and tile) and which rely on previous generic definition.
- Remove old MIPS usage of sa_restorer. This was removed since 2.6.27
(2957c9e61ee9c - "[MIPS] IRIX: Goodbye and thanks for all the fish").
- The remaining arch-specific sigaction.c are to handle ABI idiosyncrasies
(like SPARC kernel ABI for rt_sigaction that requires an additional
stub argument).
So for new ports the generic implementation should work if its uses
Linux UAPI. If SA_RESTORER is still required (due some architecture
limitation), it should define its own kernel_sigaction.h, define it and
include generic header (assuming it still uses the default generic kernel
layout).
Checked on x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabihf,
aarch64-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, powerpc-linux-gnu,
powerpc64-linux-gnu, ia64-linux-gnu and alpha-linux-gnu. I also checked the
build on all remaining affected ABIs.

These are called from the kernel with the stack at a carefully-
chosen location so that the stack frame can be restored: they must not
move the stack pointer lest garbage be restored into the registers.
We explicitly inhibit protection for SPARC and for signal/sigreturn.c:
other arches either define their sigreturn stubs in .S files, or (i386,
x86_64, mips) use macros expanding to top-level asm blocks and explicit
labels in the text section to mock up a "function" without telling the
compiler that one is there at all.

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>.

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
