Changes from previous version:

  - Remove sparc touch files in build-many-glibcs.py.

--

The pthread barrier has no support for sparc v8 since glibc 2.23
(b02840bacdefd) and although there were some discussion to add
support for LEON chips with CASA instruction [1] discussion has
stalled since.

If LEON support is still a desirable feature, I would expect to work
towards:

 - Enable USE_ATOMIC_COMPILER_BUILTINS for sparc32.
 - Fix the possible instruction emulation code issue on kernel side
   (as hinted by David Miller), so even a configuration targetting
   LEON would work on sparc v9, although suboptimal.
 - Move the generic *.S implementation to multiarch and add adapt
   the ifunc selectors.
 - Change the required multiarch to use generic implementation for
   non v9 case.
 - For the assembly specific implementation without ifunc support,
   re-evaluate if sparcv9 is really a gain over generic implementation
   with current compiler support.

The patch is straighforward, the sparc v9 is moved as the generic
implementation, the sparc v8 implementations are removed, and a
configure check is added to see if compiler sets __sparcv9__.

Checked on a sparcv9-linux-gnu.

One of my customer is still using sparc v8 LEON cpu on Gaisler's board [1].
Today, I asked him to forward this email to Gaisler in order to have some
feedback and maybe some support in upstream Glibc for LEON cpus.

For now, only old toolchains using Glibc 2.20 provided by Gaisler are available.

I know the sparc v8 support is stalled since glibc 2.23, can we wait before
merging this patch?

Thank you for bringing this issue up again. We would like to solve this
issue, as it is stopping us and our LEON3/4 users of using newer
versions of GLIBC without local patches, which is very troublesome.

Our patch in [1] aimed to be an initial solution to this issue for LEON,
however it turned out that it has problems for cases when sparc v9 could
not be detected.

Do you mean that the a sparc v9 would trap on a LEON CASA instruction
and the kernel would deal with it? If so, the problem with that approach
is that a CASA instruction aimed for LEON will be an incorrect CASA on
sparc v9 (and vice versa). It would not trap in a well defined way where
we can let the kernel take over. This is why David Miller suggested the
solution mentioned in [2], where glibc would via _dl_hwcap use LEON CASA
when we know we are on a CASA-capable LEON, use v9 CASA when we know we
are on sparc v9 and an explicit trap in other cases, letting the kernel
emulate.

We can start work towards this by submitting a Linux kernel patch adding
a hwcap bit to distinguish a CASA-capable LEON and submitting a glibc
RFC-patch like the one in [1] (using sparc v9 CASA when we know are on
sparc v9) with the change that we use LEON CASA only when knowing via
_dl_hwcap that we are on a CASA-capable LEON and trapping with ta 0x23
otherwise.

This would make glibc build for sparc32 and work on sparc v9 and
CASA-capable LEONs (when we know that we are on one of those cases). It
would if all goes right also work without changes on sparc v8 (and sparc
v9/LEON when we do not know about it) has soon as the kernel has been
updated.

David Miller started the work on handling emulation via trap 0x23 in the
Linux kernel for sparc v9 (can be seen in [3]). We are willing to test
the emulation for sparc v8 if Dave wants to handle the implementation,
or to pitch in on the implementation side if need be.

The direction I would like to make sparc and other ports to move is to
have a streamline build where glibc relies as less as possible on
arch-specific code.  It allows consolidate as much as code as possible,
incurs in less maintainability, and leverages compiler improvements.

Also, sparc32 has the __sparc32_atomic_locks where besides adding some 
contention, I think is not fully async-signal-safe and making recursive
is not really an improvement.  By Removing it allow us to use U
SE_ATOMIC_COMPILER_BUILTINS and thus simplify the internal atomic 
definitions.

I think it is better than rely on a kernel assisted helper, as David 
Miller suggested, which for sparc v8 I think it is not possible to 
implement in userspace as ARM v5 and earlier and it inherent a performance
hit with a software trap.

So one possible solution to still support LEON3/4, while still
simplifying sparc code base would be to:

  1. Refactor the sparc atomic to use USE_ATOMIC_COMPILER_BUILTINS
     and a configure test to refuse compiler configuration that emit
     libatomic calls.  This should create the expected atomic
     instructions calls on both sparcv9 and leon3/4.

  2. Remove the non required sparc32 lowlevellock.{c,h}.

  3. Move the sysdeps/sparc/sparc32/sparcv8/*.S to sysdeps/sparc/sparc32.

  4. Move both the sysdeps/sparc/sparc32/sparcv9/{mem,str,stp}*.S and
     sysdeps/sparc/sparc32/sparcv9/multiarch to sysdeps/sparc/sparc32/multiarch/
     and refactor ifunc selectors to use the sparcv8 as default and the
     sparcv9 as the HWCAP_SPARC_V9 options.

     4.1. As a side-note some implementations (such as strcat, strcspn, strspn,
	  and strpbrk) mostly likely does not worth the trouble and the generic 
	  implementation could be an improvement.

     4.2. For pthread_spin_* I would check if generic implementation could not
          be used instead (since it uses atomic operation and these would be
          created by the compiler options used to build glibc).

  5. Same as 4. for sparcv9 fpu folder.

  6. bactrace.h, cpu_relax.c, and hp-timing will need be consolidate with 
     compiler conditionals, as other architectures (hp-timing s390 for instance).


I think 1. and 2. would be the required steps to enable LEON3/LEON4 support,
but 3-6 would be good to cleanup the sparc clutter.

With these the glibc build for leon3 will be still incompatible with generic
sparcv8/sparcv9, but without a proper way to check at runtime (such as a hwcap
bit) which atomic instruction is actually supported by underlying hardware the 
other options are not really an improvement (trap on sigill for instance).

-	 * Normally, with the shift-and-add approach, if both numbers are

-	 *		  x		    32
-	 *	( 2  -  ------ ) mod 2  *  2
-	 *		   32
-	 *		  2
-	 *
-	 * (the `mod 2' subtracts 1 from 1.bbbb).  To avoid lots of 2^32s,
-	 * we can treat this as if the radix point were just to the left
-	 * of the sign bit (multiply by 2^32), and get
-	 *
-	 *	-x  =  (2 - x) mod 2
-	 *
-	 * Then, ignoring the `mod 2's for convenience:
-	 *
-	 *   x *  y	= xy
-	 *  -x *  y	= 2y - xy
-	 *   x * -y	= 2x - xy
-	 *  -x * -y	= 4 - 2x - 2y + xy
-	 *
-	 * For signed multiplies, we subtract (x << 32) from the partial
-	 * product to fix this problem for negative multipliers (see mul.s).
-	 * Because of the way the shift into the partial product is calculated
-	 * (N xor V), this term is automatically removed for the multiplicand,
-	 * so we don't have to adjust.
-	 *
-	 * But for unsigned multiplies, the high order bit wasn't a sign bit,
-	 * and the correction is wrong.  So for unsigned multiplies where the
-	 * high order bit is one, we end up with xy - (y << 32).  To fix it
